摘要
针对黑龙江电网在低负荷时电压偏高的现象,结合黑龙江某厂350 MW汽轮发电机的进相运行试验,分析了对厂用电设备的影响和调整系统电压应考虑的问题以及在实际运行中的解决方法。同时给出了发电机进相深度与低励限制的配合关系,确保了机组进相安全。
In view of the phenomenon that the Heilongjiang grid voltage is on the high side at low load, according to the test on leading phase operation of 350 MW turbine generator in a Heilongjiang power plant, the paper analy- zes the influence on house -service equipments and the problems which should be considered when adjusting sys- tem voltage and the solving method in the actual operation, and at the same time, gives the matching relationship between generator leading phase depth and low excitation limit, which ensures the safety of leading phase.
