2) secondary acceleration over-speed
二次飞升
1.
To restrain the frequent action of over-speed protection control (OPC) and to prevent secondary acceleration over-speed, it is suggested that OPC acting logic in digital electronic-hydraulic system (DEH) should be optimized and the reheat steam pressure be lowered as soon as possible after load rejection, thus providing reference for load rejecting test on large units.
介绍了湖南华润电力鲤鱼江有限公司2号机组(300MW)采用常规法的甩负荷试验,并针对抑制超速保护控制装置(OPC)的频繁动作和防止转速二次飞升的问题,提出优化数字式电液调节系统(DEH)中OPC动作逻辑和甩负荷后尽快使再热蒸汽压力降低的见解,可供大型机组甩负荷试验参考和借鉴。
