摘要
水轮发电机适时进相运行,能改善和抑制电网电压水平。通过对新安江水力发电厂4号机进相试验研究,指出发电机静稳极限、厂用电电压、定子端部结构件温升是发电机进相运行的主要限制条件。进相试验确定低励限制的范围,提高水轮发电机的进相运行能力。
Timely phase-advance operation of turbine-generators can improve and suppress the grid voltage level. Through phase-advance test and research on No. 4 Unit of Xin＇anjiang hydropower plant, it shows that the static stability limit of generator, service power voltage and temperature rise of stator end elements are the main constraints for phase-advance operation of generators. The phase-advance test can determine the range of low excitation limit and improve the phase-advance operation capability of turbine-generators.
