在新型电力系统中大型水电机组调相运行可行性分析

Feasibility Analysis of Phase Modulation Operation of Big Hydropower Units in New Power Systems

在新型电力系统中,随着新能源的不断接入,传统水电机组的运行方式由单一发电功能朝适配多能互补需求的方向变化。某水电站是大型水电机组增加调相运行方式的首次尝试。笔者详细分析了大型水电机组做调相运行对已有的发电机、水轮机及辅助系统设计的影响和对应的适配修改。该分析方法可以推广到大量类似情况的机电设备,推动传统水电机组在新型电力系统的发展中做出更大的贡献。

In the new power system,with the continuous introduction of new energy sources,the conventional hydropower station change operation from a single generation mode to to one that adapts to the complementary needs of multiple energy sources.The first attempt has been made in a hydropower station to add phase modulation operation for big hydropower units.This paper explores in detail the impact of phase-modulated operation of large hydropower units on the design and the corresponding adaptation modifications on the original equipment,such as generators,turbines and auxiliary systems.This analysis method is suitable for the similar electromechanical equipment and to promote traditional hydropower units to make greater contributions in the development of new power systems.
