海南琼中抽水蓄能电站机组发电机性能试验
|
摘要
发电机性能试验是评估发电机性能的一个重要方面,为指导机组运行的主要依据。介绍了海南琼中抽水蓄能电站发电机组发电机性能试验情况,包括发电机效率试验、电动机参数试验、温升试验、转动惯量测量试验、短时过电流试验、调相能力试验、负序电流试验等项目,试验结果表明海南琼中抽水蓄能电站3号发电机效率为98. 10%～98. 90%,其他性能指标都达到设计要求,证明该发电机的设计科学合理。
The performance test of generator is an important aspect of evaluating the performance of generators and a main basis for guiding the operation of generating units. The motor-generator performance test of Hianan Qiongzhong Pumped-storage Power Station is summarized,which includes generator efficiency test,motor parameter test,temperature rise test,moment of inertia measurement test,short-time over-current test,phase-modulation capability test and negative-sequence current test. The test results show that the efficiency of Unit 3 is 98. 10%-98. 90% and other performance indicators have reached design requirements,which prove the design of motor-generator being scientific and reasonable.
