WIRINGWhen generator supply is over load, N phase will be different with the sharing load by 3 phases (load imbalance). Hence, the voltage from N phase to 3 phases (R.S.T.) will be altered. When the rated voltage of the traditional single input’s AVR is above 220V, it will increase the voltage drift rate by using N phase as the detective input. It will also cause the voltage imbalance.EA05A can improve the above situation, and increase the generator’s rated voltage usage space, such as 380V, 440V. We can all detect by the “Phase voltage”.1. When the rated phase voltage of the generator is 220VAC, the input terminals B, C and sensing terminals A, C can join together (as show as Figure3. It’s the original setting).or connect independent.(as show as Figure2).2. When the rated phase voltage of the generator is 380V, 440V, the input terminals B, C and sensing terminals A, C must separate connect the wiring (as show as Figure 4 or Figure 5). The voltage between B and C must not be over 300 VAC.3. F+, F– terminals connect to the generator field. ( J and K ) FEXT.VR is the potentiometer (1K Ω 1W). These two terminals must be by-pass when external potentiometer is needless.P.S. : A, B, C, F+, F– the usage of wire gauge areAWG16 or 1.25mm 285°C above 600V. The EXT.VR connection wires must be made of isolated wiring.3. ADJUSTMENTSThe voltage setting for 220V / 380V / 440V and the frequency setting for 50/60HZ is show in Figure7. Please check the voltage/frequency selector setting is correct before start the generator. CAUTION :The generator or AVR may be damaged if the voltage / frequency selector setting is incorrect. UFRO DIP:Close - please refer to solid curve in Figure8. Open - please refer to dotted curve in Figure8.______________________________________________________________________________________ EA05A31. Before you turn on the generator, please turn the voltage adjustment and stability adjustment full anti-clockwise. After the generator is on and run stably, turn the voltage adjustment clockwise to reach the required out voltage. (If there is an external potentiometer, turn the external potentiometer to the middle position before adjust internal voltage potentiometer.)2. Adjust “Stability Adjustment” clockwise slowly to change the feedback time between AVR and the generator. If the adjustment is too big, it might cause the voltage instable. If too small, the load voltage will change too much at heavy load. Our suggestion is to trace by the multi-meter DCV. To adjust “stability adjustment”, you just need to make the multi-meter waving smaller. It can also improve the full load’s voltage drift rate.4. FIELD FLASHINGWhen the regulator is operated with the generator for the first time, the polarity of residual magnetism may be reversed or too small to achieve the necessary build-up voltage for the regulator. If reversing the field connections does not induce build-up, and the residual voltage is less than the specified value of 5 VAC, shut down the Prime-mover and proceed with the following steps :1. With the Prime-mover at rest and the regulator’s field output wires disconnected, apply a DC source ( NOT grounded ) of not more than 3~12 VDC with Positive to F+ and Negative to F–, in series with a current-limiting resistor of 3~5 ohms 20 watt. (The set battery is a suitable source.)2. Allow approximately 3 seconds before removing the DC source.3. With the voltage regulator disconnected ( wires 3 and 4 ), start the prime mover and measure the “ residual ” voltage available at the auxiliary winding. If this voltage is greater than 5 VAC, reconnect voltage regulator, and voltage build-up should be successful. If less than 5 VAC is measured, repeat field flashing procedure.4. If repeating steps a. and b. does not result in generator voltage build-up, and residual is greater than 5 VAC, replace voltage regulator.WARNINGThis Automatic Voltage Regulator is not equipped with loss-Sensing Protection function / Over Excitation Protection. An additional Over-Voltage Protection device for load may be required to avoid possible damage to the equipment or severe personal injury or death.5.

Excitation power is derived from a three-phase perm anent m agnet generator (PMG), to isolate the AVR control circuits from the effects of non-linear loads and to reduce radio frequency interference on the generator term inals. Sustained generator short circuit current is another feature of the PMG system.The AVR senses the voltage in the main generator winding and controls the excitation to maintain the generator output voltage within the specified lim its, com pensating for load, speed, tem perature and power factor of the generator. Three phase RMS sensing is em ployed for superior voltage regulation.Adjustable Soft start circuitry is included to provide a smooth controlled build up of generator output voltage.A frequency m easuring circuit continually m onitors the shaft speed of the generator and provides under-speed protection of the excitation system by reducing the generator output voltage proportionally with speed below a pre-settable threshold. A further enhancem ent of this feature is an adjustable volts per Hertz slope and voltage recovery tim e, to im prove the response of turbo charged engines.Current lim iting m ay be included to allow control over the amount of sustained short circuit current.Maxim um excitation is lim ited to a safe period by internal shutdown of the AVR output device. This condition remains latched until the generator has stopped.The AVR includes an over-voltage protection feature with internal shutdown of the AVR output device, plus the ability to trip an optional excitation circuit breaker if required.Provision is made for the connection of a remote voltage trim m er, allowing the user fine control of the generator's output.An analogue input is provided allowing connection to a Newage Power Factor controller or other external device with compatible output.The AVR has the facility for droop CT connection, to allow parallel running with other similarly equipped generators.

Noncondensing.DESIGN DETAILThe main functions of the AVR are:Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it. The potential divider is adjustable by the AVR Volts potentiom eter and external hand trim m er (when fitted). The output from the droop CT is also added to this signal. A rectifier converts the a.c. input signal into a d.c. signal representing generator voltage.The DC Mixer adds the Analogue input signal the generator voltage signal.The 3 Phase Rectifier converts the output of the current limit CT’s into a dc signal representing generator current. The Am plifier (Am p) com pares the generator voltage or current signals to the Reference Voltage and amplifies the difference (error) to provide a controlling signal for the power devices. The Ram p Generator and Level Detector and Driver infinitely control the conduction period of the Power Control Devices and hence provides the excitation system with the required power to m aintain the generator voltage within specified limits.The Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.The Power Supply provides the required voltages for the AVR circuitry.The Low Hz Detector m easures the period of each electrical cycle and causes the reference voltage to be reduced approxim ately linearly with speed below a presettable threshold. The Dip and Dwell circuits provide adjustm ents for greater voltage roll off and recovery tim e. A Light Em itting Diode gives indication of underspeed running.The Synchronising circuit is used to keep the Ram p Generator and Low Hz Detector locked to the Permanent Magnet Generator waveform period.Power Control Devices vary the amount of exciter field current in response to the error signal produced by the Amplifier.The Circuit Breaker provides circuit isolation of the control system in the event of an over excitation or over voltage condition.The Over Excitation Detector continuously monitors the exciter field voltage and turns off the power device if this rises above the reference leve,l for greater than the stated tim e period. An external signal is also provided to trip the Circuit BreakerThe Over Voltage Detector continuously m onitors the generator stator voltage and turns off the power device if this rises above the reference level, for greater than the stated tim e period.

Terminals 1 and 2 on the AVR will be fitted with a shorting link if no hand trimmer is required.WARNING! Do not increase the voltage above the rated generator voltage. If in doubt, refer to the rating plate mounted on the generator case.WARNING! Do not ground any of the hand trim m er terminals, as these could be above earth potential. Failure to observe this could cause equipment damage. If a replacement AVR has been fitted or re-setting of the VOLTS adjustm ent is required, proceed as follows:1. Before running generator, turn the VOLTS control fully anti-clockwise.2. Turn rem ote volts trim m er (if fitted) to m idway position.3. Turn STABILITY control to midway position.4. Connect a suitable voltmeter (0-300V ac) across line to neutral of the generator.5. Start generator set, and run on no load at nominal frequency e.g. 50-53Hz or 60-63Hz.6. If the red Light Emitting Diode (LED) is illuminated, refer to the Under Frequency Roll Off (UFRO) adjustment.Continued…..VoltsTD_MX321.GB_11.06_05Barnack Road • Stamford • Lincolnshire • PE9 2NB Tel: 00 44 (0)1780 484000 • Fax: 00 44 (0)1780 484100© 20067. Carefully turn VOLTS control clockwise until rated voltage is reached.8. If instability is present at rated voltage, refer to stability adjustment, then re-adjust voltage if necessary. 9. Voltage adjustment is now completed.STABILITY ADJUSTMENTThe AVR includes a stability or damping circuit to provide good steady state and transient perform ance of the generator.A jum per link selector is provided to optim ise the response of the stability circuit to various size generators. The link should be positioned as shown in the diagram according to the kW rating of the generator.The correct setting of the Stability adjustm ent can be found by running the generator at no load and slowly turning the stability control anti-clockwise until the generator voltage starts to becom e unstable. The optimum or critically damped position is slightly clockwise from this point (i.e. where the m achine volts are stable but close to the unstable region).UNDER FREQUENCY ROLL OFF (UFRO) ADJUSTMENTThe AVR incorporates an underspeed protection circuit which gives a volts/Hz characteristic when the generator speed falls below a presettable threshold known as the "knee" point. The red Light Em itting Diode (LED) gives indication that the UFRO circuit is operating.The UFRO adjustm ent is preset and sealed and only requires the selection of 50 or 60Hz and 4 pole or 6 pole, using the jumper link as shown in the diagram.For optim um setting, the LED should illum inate as the frequency falls just below nom inal, i.e. 47Hz on a 50Hz system or 57Hz on a 60Hz system. DROOP ADJUSTMENTGenerators intended for parallel operation are fitted with a quadrature droop C.T. which provides a power factor dependent signal for the AVR. The C.T. is connected to S1, S2 on the AVR, (see generator wiring diagram for details). The DROOP adjustm ent is norm ally preset in the works to give 5% voltage droop at full load zero power factor.Clockwise increases the am ount of C.T. signal injected into the AVR and increases the droop with lagging power factor (cos Ø). With the control fully anti-clockwise there is no droop.TRIM ADJUSTMENTAn analogue input (A1 A2) is provided to connect to the Newage Power Factor Controller or other devices. It is designed to accept dc signals up to +/- 5 volts.WARNING! Any devices connected to this input must be fully floating and galvanically isolated from ground, with an insulation capability of 500V ac. Failure to observe this could result in equipment damage.TRIM ADJUSTMENT continuedThe dc signal applied to this input adds to the AVR sensing circuit. A1 is connected to the AVR 0 volts. Positive on A2 increases excitation. Negative on A2 decreases excitation. The TRIM control allows the user to adjust the sensitivity of the input. With TRIM fully anti-clockwise the externally applied signal has no effect. Clockwise it has m axim um effect.Normal setting is fully clockwise when used with a Newage Power Factor Controller.OVER EXCITATION (EXC) ADJUSTMENTThis adjustment is set and sealed in the works and should not be tam pered with. An over excitation condition is indicated by the illum ination of the red LED which also indicates under-speed running and over-volts.The generator must be stopped to reset an over-excitation trip.DIP ADJUSTMENTThis feature is mostly used when the generator is coupled to turbo charged engines with lim ited block load acceptance. The feature works by increasing the V/Hz slope to give greater voltage roll off in proportion to speed. With the DIP control fully anti-clockwise, the generator voltage will follow the normal V/Hz line as the speed falls below nominal. Turning the DIP control clockwise provides greater voltage roll off aiding engine recovery. DWELLThis feature is mostly used when the generator is coupled to turbo charged engines with lim ited block load acceptance. The feature works by introducing a delay between speed recovery and voltage recovery and allows a greater DIP setting without instability. With the DWELL control fully anti-clockwise, the generator voltage will follow the V/Hz line. Turning the DWELL control clockwise increase the delay tim e between speed recovery and voltage recovery.CURRENT LIMIT (I LIMIT) ADJUSTMENTThis feature is mostly used to limit short circuit current or to provide a current lim it on m otor starting. To use this feature, current lim it CT’s of the correct ratio need to be connected to the AVR S1 S2 terminals. There is an internal tim e lim it of 10 seconds. Consult the factory before using this feature.OVER VOLTAGE (OVER V) ADJUSTMENTThis adjustment is set and sealed in the works and should not be tam pered with. An over voltage condition is indicated by the illum ination of the red LED which also indicates under-speed running and over-excitation.The generator m ust be stopped to reset an over-voltage trip. RAMPThe AVR includes a soft start or voltage ramp-up circuit to control the rate of voltage build up, when the generator runs up to speed.

AVR自动电压调压器
A VR自动电压调压器AVR是英文automatic voltage regulator的缩写，是三相同步发电机的重要部件。
AVR是一种半波相近控制闸流管型的自动电压调节器,是交流发电机励磁系统的一部分。
除调节发电机的电压外,AVR还具有低速和无检测信号保护的功能，以保证对发电机安全可靠的控制，励磁电源直接由发电机输出端导出。
AVR电源电路使用的高效半导体保证了由剩磁获得的起励电压。
西电SDMO小功率机组mecc alte spa电球普遍采用SR7 AVR，LEROY SOMER电球采用R230、R448、R449等AVR。
其工作原理都差不多，AVR与主定子绕组和励磁绕组连接，对输出电压提供精度为±1％的闭环控制。
在从主定子获得电源外,AVR还从输出绕组取样电压以实现对输出的控制。
AVR根据获得的采样数据控制输出到励磁系统的电流,通过可控硅导通角的调节,把无功功率、功率因数和输出电压控制在一定的范围内。
国产和印度机的AVR接线方式一样，只需要连接E＋、E－和U、V相绕组取样电压和零线，根据取样电压与设定电压的误差放大，经脉宽调制，通过可控硅导通角的调节控制输出励磁电流从而调节发电机的输出电压。

自动电压调节(AVR)-详细介绍
自动电压调整zidong dianya tiaozheng automaticvoltage regulation,AVR同步发电机的励磁控制系统对机端电压实施自动调节的功能。
由于同步发电机具有电枢反应，其端电压随负载变化而波动。
最早期的透平发电机运行时，电压是人工调节的，由运行人员监视并调节励磁机磁场回路中的变阻器来维持发电机的端电压。
后来研制成机电型自动电压调节器，同步发电机端电压的调整才实现了自动化。
励磁控制系统自动电压调节器、励磁机和同步发电机形成的反馈控制系统，见图1。
自动电压调节器以发电机的运行参数(电压、电流、功率因数等)作为反馈控制信号，调节励磁电流以维持机端电压为给定值，实现并联运行机组间的无功功率自动分配和提高发电机组运行的稳定性等。
自动电压调节器(AVR)是励磁控制系统的核心部件，它所选用元件的性能和所采用的调节准则对调节系统的品质起主导作用。
自动电压调节器是通过调节励磁电流来实现电压调整的，同时它还兼有强行励磁、强行灭磁等控制功能，所以也称为自动励磁调节器。
图1 励磁控制系统图发展简况50年代以前只有机电型自动电压调节器，它的执行部件直接作用于变阻器，改变励磁机的磁场电阻，从而改变发电机励磁，达到调节机端电压的目的。
由于它需要克服摩擦力，具有呆滞区，所以发电机组不能在人工稳定区域运行。
它的任务只是调整电压和无功分配。
50年代磁放大器出现后，电磁型自动电压调节器开始问世，这种自动电压调节器的综合放大和功率放大部件都采用磁放大器，用改变励磁机磁场绕组合成安匝的办法来调节发电机的端电压，它没有机械运动部件，因而无呆滞区，发电机组可以在人工稳定区域运行。
这种调节器可靠性高、寿命长。
它的主要缺点是时间常数较大。
60年代由于半导体器件的发展，又出现了半导体型自动电压调节器。
半导体器件几乎没有时延，使用寿命长，70年代初半导体型的自动电压调节器就得到了广泛的应用。
当前大规模集成电路和计算机技术已日益成熟，应用计算机技术的数字型自动电压调节器(digital automatic voltage reg-ulator，DAVR) 已研制成功并投入工业运行。

发电机自动电压调节器AVR
发电机自动电压调节器AVR发电机电压调节器简介发电机电压调节器通过对发电机交流励磁机励磁电流的控制，实现对发电机输出电压的自动调节。
发电机电压调节器可满足普通60/50Hz及中频400Hz 单机或并列运行的发电机使用。
电压调节器（简称AVR），是专门为配套基波、谐波复式励磁或装配有永磁发电机励磁（PGM系统）的交流无刷发电机而设计。
发电机电压调节器工作原理由于发电机与发动机的传动比是固定的，所以发电机的转速将随发动机转速的变化而变化。
汽车在运行过程中，发动机转速变化范围很大，发电机的端电压也将随发动机的转速变化而在很大范围内变化。
发电机对用电设备供电和向蓄电池充电，都要求其电压稳定，所以为使电压始终保持在某一数值基本不变，就必须对发电机的输出电压进行调节。
发电机电压调节器基本分类：（1）触点式电压调节器触点式电压调节器应用较早，这种调节器触点振动频率慢，存在机械惯性和电磁惯性，电压调节精度低，触点易产生火花，对无线电干扰大，可靠性差，寿命短，现已被淘汰。
（2）晶体管调节器随着半导体技术的发展，采用了晶体管调节器。
其优点是：三极管的开关频率高，且不产生火花，调节精度高，还具有重量轻、体积小、寿命长、可靠性高、电波干扰小等优点，现广泛应用于东风、解放及多种中低档车型。
（3）集成电路调节器集成电路调节器除具有晶体管调节器的优点外，还具有超小型，安装于发电机的内部（又称内装式调节器），减少了外接线，并且冷却效果得到了改善，现广泛应用于桑塔纳。
奥迪等多种轿车车型上。
（4）电脑控制调节器由电负载检测仪测量系统总负载后，向发电机电脑发送信号，然后由发动机电脑控制发电机电压调节器，适时地接通和断开磁场电路，即能可靠地保证电器系统正常工作，使蓄电池充电充足，又能减轻发动机负荷，提高燃料经济性。
如上海别克、广州本田等轿车发电机上使用了这种调节器。
2．电子调节器按所匹配的交流发电机搭铁型式可分为：（1）内搭铁型调节器适合于与内搭铁型交流发电机所匹配的电子调节器称为内搭铁型调节器；（2）外搭铁型调节器适合于与外搭铁型交流发电机所匹配的电子调节器称为外搭铁型调节器。

考图 3） 使用温度 —40 C 〜60 C.
3．使用时注意事项
（1） 安装时注意事项： （配置参考图 1） 安装、连接、检查的作业由有专业知识人员实施 . 将调节器安装于发电机内防潮、 腐蚀
且防止他人不易碰触的地方。
在一般运转状况下，调节器表面温度会超过 60C, 运转时，
请勿碰触调节器散热板已张贴警告标志。
4．调整
⑴低频调整（U/F ）。
在50Hz 使用时，将"跨线"插入C, 50之间（出厂设置），在60Hz 使用将“跨 线”插入
C ，60之间。
U/F 电位器为设定低频保护之频率动作值， 其设定步骤：
使引擎启动且电压建立，调整引擎转至所需之低频值。
缓慢调整 U/F 旋钮使AVR 上红色
指示灯亮即可（出厂设定50Hz 时47Hz,60Hz 时57Hz ）。
其保护动作如图3
（当红色（LED ）指示灯亮起时，表示频率不足在此状况输出电压会因低频保护电
路动作而下降，防止过大的激磁电流损坏磁场定子线圈）。
（2）电压调整（VOLT 。
调整 “电压电位器” 至额定值（顺时针增加 ）。
当使用外部电压调整时 （请参考 图 4）
于“ 1”，“ 2”间跨接VR,1K 1/2W.无外接VR 时“1”，“ 2”必须短
接。
输入电源 侦测电源 最大输出 电压调整率 发电机磁场电阻 外接电位器 1K 电压建立 （ 初期 ）
⑶稳定调整（STAB。
调整“稳定调整”可使发电机之输出电压稳定，但过度的调整会使发电机在重负载下瞬间电压变动率变大。
建议使发电机组空载运行，检查转速是否正确，稳定
“稳定调整”电位器顺时针旋转到底，然后缓慢地逆时针旋转，直到发电机电压开始波动。
正确的设定是从这位置再稍稍顺时针转动（即在这点上发电机电压稳定，但非常接近不稳定区）。
⑷励磁脱扣（EXC
当两相间或一相与中性线发生短路时，为了保护发电机绕组，AVR内部有一个过励磁检测线路，该线路一旦探测到过高的励磁电流，就会切断励磁。
励磁脱扣设置不当将使发电机在负载或稍过载时产生电压骤然下降，同时发光二极管一直亮着。
正确的设置是端子X和XX之间的电压为70V± 5%
5. 激磁:
当发电机之剩磁不足使AVR建立电压时，必须由外部来激磁，如图2。
在引擎运转后，
用一个12V电池，负极接AVR的XX接线柱，正极通过一个二极管接AVR接线柱X,在发电机电压建立在额定电压之30 %时即停止激磁，。
非常重要：（必须使用二极管以保证AV不被损坏）
7．发电机并联操作
了解以下关于并联运行的注意事项，对安装和设置调差装置非常重要。
当发电机和其它发电机并联运行或和电网并网时，最基本的要求为发电机具有与并联的机组或电网相同的相序，同时以下的几个条件也必须符合。
1. 频率必须相同（允许极小的误差）。
2. 电压必须相同（允许极小的误差）。
3 .电压相位角必须相同（允许极小的误差）。
请特别注意：
1. 当并联开关合闸时，如未满足以上三个条件，将对发电机产生过度的机械冲击和电流
冲击，并会导致设备损坏。
2. 有功功率由发动机提供，其调速器特性决定了并联机组间的有功功率分配。
3. 无功功率由发电机提供，其励磁控制特性决定了无功功率的分配。
8.下垂调差装置（DROOP 分配无功功率最常用的方法是建立一个随着功率因数下降（即无功功率增加）而下降的
电压特性。
这个特性依靠一个电流互感器将电流的相位角（即功率因数）反馈至A VR
完成。
根据不同的负载，应采用下列设置，以下数值都以额定电流为基准。
1. 功率因数为0.8 时（额定电流时）下垂值需设定为3％，
2 .功率因数为0时（额定电流时）下垂值需设定为5%, 顺时针针旋转“下垂调节”电
位器即可增加下垂。
一般在额定电流时功率因数为零的情况下，下垂5%已足以满足无功率分配的需要。
（注1 .电流互感器必须安装在输出三相中的其中一相，且不可与AVR之侦测电源同相。
注2 .将所有发电机电压设置为相同值非常重要，至于下垂调节的精度是次要的。
注3 .当一台发电机单独运行时，若设置下垂调节为功率因数0.8 满负载时，它不能保持通常的0.5 %的电压调整率。
因此在单独运行时，端子S 1—S 2间需短接，以恢复单机运行时的调整率。
