| 摘 要： | 为了解决张家口发电厂7号机组中压缸冷态启动中的系统控制问题,分析了中压缸启动的特点、机组及控制系统的现状,提出了控制系统需要解决的问题.在此基础上给出了机组中压缸启动的控制方案,并对高压缸预暖控制、机组启动方式的选择、阀切换逻辑、中压调门开启曲线整定、通风阀的控制和旁路自动投入进行了详细介绍.该方案在张家口发电厂7号机组首次采用中压缸启动中获得成功.运行实践表明,该方案控制逻辑正确、合理,能满足机组系统的要求.

| Abstract: | In order to resolve the cool state IP start system control questions of the #7 turbine system,Zhangjiakou power plant,the characters of IP start and the state of turbine and its control system has been analyzed in this paper.The question needed to be resolved by the control system is prompted.Based on this,the control model for IP start is given.The pre-warm control of HP,the Start mode Selection,the valve exchange logic,the opening curve regulation of IP regulation valve,the fan valve control and the turn on of bypass auto control are discussed in detail.This model is successfully applied in the first IP starrt of #7 turbine system,Zhangjiakou power plant.The operation result shows that the control logic is right and reasonable.It's available for the system requirements. |
