摘　　要：以国电汉川发电有限公司2×1 000MW超超临界机组旁路系统为例,从热工控制角度分析其40%BMCR高压旁路和低压旁路的控制系统的功能及其在启动运行阶段各种控制模式.通过调整参数可以进一步优化旁路性能,通过对高旁减温阀PID设置更合理的比例系数和积分时间,使温度控制稳定并进一步提高机组控制水平。According to the problem analysis of Guodian Hanchuan Power Generation Co.,Ltd 2×1 000 MW ultra-supercritical unit bypass control system,the control functions of he 40% HP bypass and the 40% LP and various control modes during start-up and operation are illustrated from thermal process. The temperate control was stabilized and the unit control level was improved through parameters ad-j ustment,bypass control system optimization and setting reasonable proportion coefficient and inte-gration time of PID.
