摘要
为解决并联运行发电机组采用常规甩无功负荷法测量发电机电压调差率误差大这一难题,提出利用改变同一工况下发电机电压调差率而引起无功负荷和机端电压波动的新方法进行调差率测量,实测结果误差小、精度高,能满足运行的需要,很好地克服了常规测量方法本身存在的缺陷。
In order to solve the problem of traditional reactive power load rejecting method which has large error when used to measure the voltage adjustment ratio of parallel operation generator, a new method is proposed which make use of the fluctuation of reactive power load and voltage caused by changing generators＇ voltage adjustment ratio under same operation condition to measure adjustment ratios. Test results show that the proposed method has smaller error, higher precision, and can not only satisfy the need of operation, but also overcome shortcomings of traditional measurement method.
