摘要
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。
The load rejecting test with conventional method on Unit 2 (300 MW) of China Resources Power Hunan Liyujiang Co., Ltd. is described. 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.
