摘　　要：湖南华润电力鲤鱼江有限公司 2号机 30 0MW机组甩负荷试验之前 ,进行了准备工作 ,并对机组DEH设计逻辑作了一些改进。在分析了第 1次甩 10 0 %负荷试验失败的原因后 ,再进行了甩 10 0 %负荷试验。由于该型机组中压调节汽门IV不参与转速和负荷调节 ,导致甩负荷后OPC频繁动作。通过采取有效的措施 ,使甩 5 0 %负荷和甩 10 0 %负荷后 ,OPC仅动作 2次 。Before load rejection test for No.2 300 MW unit in Huarun Liyuejiang Power Ltd. Com., a preparation has been made, including improvement of DEH design logic for the unit. After analysis on the causes of the failure for the first 100% load rejection test, a 50% load rejection test was completed. Since the MP governor IV didn't participate in speed and load control, OPC is frequently under action after load reject. After some effective measures were taken OPC is in action twice after 50% and 100% load rejection tests and the speed was controlled at synchronous speed.
