1.编制目的Compile Purpose

为了指导和规范系统及设备的调试工作,检验系统的性能,发现并消除可

能存在的缺陷,检查热工联锁、保护和信号装置,确保其动作可靠。使系统及设

备能够安全正常投入运行,制定本方案。

This commissioning procedure is compiled to guide and standardize the practice of testing and adjusting to facilitate proofing of system performance, finding and repairing of possible defects, thus ensuring that the equipment and system can be brought into operation safely and smoothly.

2.调试范围Scope of commissioning

2.1协调控制系统是大型火力发电机组的主要控制系统,它将锅炉和汽轮发电机

作为一个整体考虑来进行控制,协调锅炉控制系统与汽轮机控制系统的工作,以

消除锅炉和汽轮机在动态特性方面的差异,使机组既能够适应电网负荷变化的需

要,又能够保证机组的安全稳定经济运行。机炉协调控制系统直接作用的控制对

象是锅炉主控制系统和汽轮机主控制系统,然后再由这两个主控系统分别控制各

自的子控制系统如锅炉燃烧控制子系统、锅炉给水控制子系统和汽轮机电液调节

子控制系统等。

As a major control system of large thermal power generating unit, coordinated control system (CCS) treats the boiler and turbine-generator as a whole, harmonizes the effect of boiler and turbine control systems, and compensates the difference in boiler and turbine-generator dynamic characteristics, thereby meeting changing demand of the Grid and also ensuring safe and economic operation of the unit. The CCS exerts influence directly upon the main control system of boiler and that of turbine, then these two systems exert influence respectively on their own subsystems such as boiler combustion control, boiler feed water, turbine digital electro-hydraulic control (DEH). 2.2 印度BALCO扩建4 x300 MW燃煤电站工程协调系统有如下几种控制方式:BALCO EXPANSION PROJECT 4×300 MW THERMAL POWER PLANT CCS has following control modes:

手动方式

Manual mode

机跟随控制方式(TF)

Turbine follow control mode

炉跟随控制方式(BF)

Boiler follow control mode

机炉协调控制方式

Coordinated boiler-turbine control mode

3.调试前必须具备的条件Conditions of commissioning

3.1该系统授电工作已经进行完毕并检验合格,软件恢复工作已经结束并检验合

格。

CCS energizing and software recovery shall be finished, fulfilling the requirements. 3.2该系统硬件检查和I/O通道精确度检查工作已经结束并检验合格。

CCS hardware inspection shall be finished, and I/O channels accuracy shall be checked up to standard.

3.3主要热控设备、控制机柜、执行机构和变送器已安装就位。

I&C devices, control cabinets, actuators, and transmitters shall be installed.

4.调试步骤Process of commissioning

4.1静态调试

Static test

4.1.1电缆接线检查

Inspection of cable wiring

检查协调控制机柜与其他控制系统之间的电缆接线是否正确。包括:与DEH控制系统之间的接线,与热工信号报警系统之间的接线。

Check the cable between CCS cabinets and other control systems are wired correctly, including cables to DEH control system and to I&C alarming signal system.

4.1.2信号传输试验

Signal transmission test

检查输入、输出信号联络通道是否畅通无阻,各个联络信号在工程单位和量程上

是否一致和合理。

Check the I/O channels work normal, with interchange signals consistent in unit and range.

4.1.3静态参数的整定

Static parameters setting

各个PID调节器参数可根据机组设计额定参数及燃料的发热量进行理论计算后

进行初步整定或按经验值进行初步整定,作为机组首次投入协调控制系统的原始

动态参数。

The parameters of each PID regulator can be set preliminarily from calculation based on the unit rated parameters and fuel heating value, or from operational experience. These parameter values are used as the original dynamic parameters when the CCS initial is put into operation for the first time.

4.1.4检查各子控制系统按照机炉主控指令变化是否正确。

Check that each subsystem changes c orrectly, in accordance with the main control
