Plant Model Generation for PLC Simulation
Hyeong-Tae Park
Abstract:This paper reports an automated procedure for constructing a plant model for PLC simulation. Since PLC programs contain only the control logic without information on the plant model, it is necessary to build the corresponding plant model to perform the simulation. Conventionally, a plant model for PLC simulation has been constructed manually, which requires much effort and indepth knowledge of the simulation. As a remedy for this problem, we propose an automated procedure for generating a plant model from the symbol table of a PLC program. To do so, we propose a naming rule for PLC symbols so that the symbol names include sufficient information on the plant model. By analysing such symbol names, we extract a plant model automatically. The proposed methodology has been implemented and test runs performed.

电力系统
1 电力的技术特点
电力具有独特的技术特点，这使得电力工业具有独特的行业特点。
1.无形性。用户不能用人体感官直接察觉千瓦时的用电量。
2.质量。供电质量可由供电连续性或供电可靠性、在标准电压等级下的电压均等性、交流电压频率的正确不变性来度量。
3.电力的贮存。与大多数行业不同，电力部门必须随时根据用电的需求生产出电力来，因为电能无法贮存。
4.对供电负责。电由电力部门输送到用户，因此必须对安全、可靠供电负责。
5.对公众的安全。电力部门须对公众及其技术人员提供稳妥的保护。
2 电力系统的规划
预期到电力部门的供电负荷将持续增长，电力系统的容量也持续增大。远期规划主要是保证这种扩建在技术上是适宜的，在造价上是合理的，与增长模式是相符的。远期规划者碰到的困难包括：不同地域和不同时间负荷增长的不确定性、新发明新技术发展的可能性。优异的系统规划要努力做到全系统设计的最优化，而不能为了系统某部分造价的最小化而不顾其它部分的影响。近年来，已经强调了规划和运行的经济性。现在则越来越强调可靠性和环境方面的因素。
在作出规划前，须要仔细考虑许多因素：
（1）设备的决策具有远期效应，这需要15—25年的预期和研究。
（2）有许多发电途径可选择：核电、基荷火电、中等规模燃气轮机发电或水电，以及大型、中型、小型电厂和各种形式的蓄能。
（3）有多种送电途径可选择，例如由交流或直流，架空线或地下电缆送电并有各种电压等级。

1．变压器是变换交流电压、电流和阻抗的器件，当初级线圈中通有交流电流时，铁芯（或磁芯）中便产生交流磁通，使次级线圈中感应出电压（或电流）。变压器由铁芯（或磁芯）和线圈组成，线圈有两个或两个以上的绕组，其中接电源的绕组叫初级线圈，其余的绕组叫次级线圈。
2. 理想变压器不计一次、二次绕组的电阻和铁耗，其间耦合系数K=1 的变压器称之为理想变压器描述理想变压器的电动势平衡方程式为e1(t) =-N1dφ/dt、e2(t)=-N2dφ/dt若一次、二次绕组的电压、电动势的瞬时值均按正弦规律变化，则有不计铁心损失，根据能量守恒原理可得由此得出一次、二次绕组电压和电流有效值的关系令K=N1/N2，称为匝比（亦称电压比）。
3. 变压器的结构简介（1）铁心是变压器中主要的磁路部分。通常由含硅量较高，厚度分别为0.35 mm\0.3mm\0.27 mm，表面涂有绝缘漆的热轧或冷轧硅钢片叠装而成铁心分为铁心柱和横片俩部分，铁心柱套有绕组；横片是闭合磁路之用铁心结构的基本形式有心式和壳式两种（2）绕组是变压器的电路部分，它是用双丝包绝缘扁线或漆包圆线绕成变压器的基本原理是电磁感应原理，现以单相双绕组变压器为例说明其基本工作原理:当一次侧绕组上加上电压Ú1时，流过电流Í1，在铁芯中就产生交变磁通Ø1，这些磁通称为主磁通，在它作用下，两侧绕组分别感应电势É1，É2，感应电势公式为：E=
4.44fNØm 式中：E--感应电势有效值，f--频率，N--匝数，Øm--主磁通最大值，由于二次绕组与一次绕组匝数不同，感应电势E1和E2大小也不同，当略去内阻抗压降后，电压Ú1和Ú2大小也就不同。当变压器二次侧空载时，一次侧仅流过主磁通的电流（Í0），这个电流称为激磁电流。当二次侧加负载流过负载电流Í2时，也在铁芯中产生磁通，力图改变主磁通，但一次电压不变时，主磁通是不变的，一次侧就要流过两部分电流，一部分为激磁电流Í0，一部分为用来平衡Í2，所以这部分电流随着Í2变化而变化。当电流乘以匝数时，就是磁势。上述的平衡作用实质上是磁势平衡作用，变压器就是通过磁势平衡作用实现了一、二次侧的能量传递。变压器技术参数对不同类型的变压器都有相应的技术要求、可用相应的技术参数表示。如电源变压器的主要技述参数有：额定功率、额定电压和电压比、额定频率、工作温度等级、温升、电压调整率、绝缘性能和防潮性能，对于一般低频变压器的主要技述参数是：变压比、频率特性、非线性失真、磁屏蔽和静电屏蔽、效率等。

In recent years, with power electronic technology, microelectronic technology and modern control theory infiltrating into AC electric driving system, inverters have been widely used in speed-regulating of AC motor. The variable frequency speed-regulating system which consists of an induction motor and a general inverter is used to take the place of DC speed-regulating system. Because of terrible environment and severe disturbance in industrial field, the choice of controller is an important problem. Neural network inverse control was realized by using industrial control computer and several data acquisition cards. The advantages of industrial control computer are high computation speed, great memory capacity and good compatibility with other software etc. But industrial control computer also has some disadvantages in industrial application such as instability and fallibility and worse communication ability. PLC control system is special designed for industrial environment application, and its stability and reliability are good. PLC control system can be easily integrated into field bus control system with the high ability of communicationconfiguration, so it is wildly used in recent years, and deeply welcomed. Since the system composed of normal inverter and induction motor is a complicated nonlinear system, traditional PID control strategy could not meet the requirement for further control. Therefore, how to enhance control performance of this system is very urgent.

A: The Utility Interface with Power Electronic System
Introduction
We discussed various powerline disturbances and how power electronic converters can perform as power conditioners and uninterruptible power supplies to prevent these poweline disturbances from disrupting the operation of critical loads such as computers used for controlling important processes, medical equipment, and the like. However, all power electronic converters (including those used to protect critical loads) can add to the inherent powerline disturbances by distorting the utility waveform due to harmonic currents injected into the utility grid and by producing electromagnetic interference, To illustrate the problems due to current harmonics ih in the input current i s of a power electronic load, consider the simple block diagram of Fig. 1-6A-1. Due to the finite (non-zero) internal impedance of the utility source which is simply represented by Ls in Fig. l-6A-1, the voltage waveform at the point of common coupling to the other loads will become distorted, which may cause them to malfunction. In addition to the voltage waveform distortion, some other problems due to the harmonic currents are as follows: additional heating and possibly overvoltages (due to resonance conditions) in the utility's distribution and transmission equipment, errors in metering and malfunction of utility relays, interference with communication and control signals, and so on. In addition to these problems, phase-controlled converters cause notches in the utility voltage waveform and many draw power at a very low displacement power factor which results in a very poor power factor of operation.

A1.1外文资料题目
26.22 接地故障电路开关
我们目前为止报道的接地方法通常是充分的, 但更加进一步的安全措施在某些情况下是必要的。假设例如, 有人将他的手指伸进灯口（如Fig.26.45示）。虽然金属封入物安全地接地, 但那人仍将受到痛苦的震动。或假设1个120V 的电炉掉入游泳池。发热设备和联络装置将导致电流流入在水池中的危害，即使电路的外壳被安全地接地，现在已经发展为当这样的事件发生时，设备的电源将被切断。如果接地电流超过5mA ，接地开关将在5 ms 内跳掉，这些装置怎么运行的？
如Fig.26.46所示，一台小变流器缠绕上导线 ，第二步是要连接到可能触发开合120 V 线的一台敏感电子探测器。 在正常情况下流过导体的电流W I 与中性点上的电流N I 准切的相等，因此流经核心的净潮流(N W I I -)是零。 结果，在核心没有产生电流，导致的电压F E 为零，并且开关CB 没有动作。 假设如果某人接触了一个终端(图Fig.26.45示)，故障电流F I 将直接地从载电线漏到地面，这是可能发生的。如果绝缘材料在马达和它的地面封入物之间断开，故障电流也会被产生。在以下任何情况下，流经CT 的孔的净潮流等于F I 或L I ，不再是零。电流被产生，并且产生了可以控制CB 开关的电压F E 。 由于5 mA 不平衡状态只必须被检测出，变压器的核心一定是非常有渗透性的在低通量密度。 Supermalloy 是最为常用的，因为它有相对渗透性典型地70000在通量密度仅4mT 。
26.23 t I 2是导体迅速发热的因素
它有时发生于导体短期内电流远大于正常值的情况下，R I 2损失非常大并且导体的温度可以在数秒内上升几百度。例如，当发生严重短路时，在保险丝或开关作用之前，会有很大的电流流过导体和电缆。 此外，热量没有时间被消散到周围，因此导体的温度非常迅速地增加。 在这些情况下什么是温度上升？ 假设导体有大量m ，电阻R 和热量热容量c 。 而且，假设电流是I ，并且那它流动在t 少于15秒期间。 在导体上引起的热
Rt I Q 2=
从Eq.3.17，在功率一定的情况下我们可以计算导体上升的温度差：
t mc Q ∆=
因此由
t mc Rt I ∆=2
得出 )(2t I mc
R t =∆ 因而断定一个导体的温度上升取决于t I 2因素。
众所周知：高温会破坏包裹在导体表面的绝缘。因此确定温度上升因素t I 2是非常重要的，因为它在短路情况下，决定导体的温度上升。例如，一个最初在温度C ︒90的No.2AWG 铜导体，如果它的温度在短路时必须控制在C ︒250，不可能承受t I 2因素超出s A 261022⨯。
一般来说，t I 2因素可以被用于计算知道(a)导体的横断面， (b)它的构成(铜或铝)和(c)它能承受的最高温度。 铜和铝的t I 2因素给出以下等式：
对于铜导体， )234234(log 105.110
10242θθ++⨯=m A t I 对于铝导体， )234234(log 102.50
10242θθ++⨯=m A t I 其中：
I=短路电流（A ）
t=短路的时间（s ）
A =导体没有计算空的空间的网横断面（mm 2
） =0θ导体的最初温度(c ︒)
=m θ导体的最后温度(c ︒)
例子26-1___________________________________________
一条由铝导体NO3.AWG 制成且横断面为26.6mm 的架空线。 在正常情况下这个导体可能连续运载电流160 A 。
a.在短路期间，计算最大可允许的t I 2因素，知道最初的温度是c ︒80，并且最大温度不应该超出c ︒250。
b.在此架空线上有2000A 的最大短路电流，问它在无需超出c ︒250温度极限的情况下运行多久？ 解答
a.由Eq.26.5我们发现 )234234(log 102.50
10242θθ++⨯=m A t I =80

b.2000A 电流可运行的时间t

t = 1.75s
例子26-2___________________________________________
它提议使用NO.30AWG 铜丝作为一根临时保险丝。 如果它最初的温度是50c ︒，计算以下： a.需要熔化导线的t I 2 (铜熔化在1083c ︒)
b.如果短路电流是30A ，需要熔化导线的时间
解答
a.由我们有的Eq.26.4 )50
2341083234(log 0507.0105.1110242++⨯⨯=t I =197 A s 2
b.从电流为30A 可得到
t I 2=197
301972=t
t=0.22s
因此，保险丝可能在220ms 后被熔断。
26.24 保险丝的角色
为了保护导体在短路期间免受过热温度的毁坏，一系列保险丝必须安置在导体上。 保险丝是经过选择的，目的是它的规定值t I 2比将保护导体上升的过热温度要少。 实际上，我们要保险丝在导体获得一个危险温度之前熔断，通常采取是250c ︒。 实践上，保险丝的规定值t I 2远在产生导体温度的t I 2最大限度之下。 尽管如此，导体的规定值t I 2在保险丝的选择时是一个重要的因素。
26.25 在建筑内的电子设备安装
电子分布式系统在建筑内是消费者和电能初始源之间最后的链接。 所有这一类建筑内部的分布式系
