摘要
1000MW机组经过热网系统的改造后,需要更大的抽汽量被供热使用,低压缸负荷调节幅度及响应速度降低,导致机组响应一次调频能力减弱。结合电厂实际运行情况,对供热调门进行适当优化,作为一次调频能力的补充手段,为机组安全经济运行提供了保障。
After heating network renovation,unit needs more extraction steam capacity for heating operation,low pressure cylinder load regulation range and velocity decrease,which makes unit primary frequency regulation capacity weak.Combined with electrical power plant practice,the author optimizes heating adjusting valve to work as supplement for primary frequency regulation capacity,which supports safe and economic operation for unit.
