水电站频率调节

Frequency Adjusting for Hydroelectric Power Station

本文叙述了引水管道和发电机设计对水电站电力输出频率特性的影响，提供了估算频率调节理想品质函数的方法。具有电子电路的现代调速器，甚至在极不利的情况下都能抑制波动，但是倘若设计的水力系统惯性过大，则调速器不能有效改善频率调节的质量。

This article talks about how the design of pipelines and generators affects the frequency characteristics of power outcome of a hydroelectric power station, and provides a method of estimating an ideal character function for frequency adjusting. With an electronic speed regulator equipped, fluctuation even in worst situations can be restrained. However, if the inertia designed of the hydraulic power system exceeds the boundary, the speed regulator might fail to improve the quality of the frequency adjustment.
