同步发电机“四等”电势线的建立及应用

The Establishment and Application of Four Isoelectric Electric Potential of Synchronous Generator

依据隐极式同步发电机并网及工况点调节过程的电势向量平面图找出四类等电势曲线,并根据各类等电势曲线调节发电机,同时确定以各类电势线形成的安全运行区域,在安全运行区域内利用二元法确定出发电机的瞬时工况点。

Based on the potential vector planar graph of the grid connection and regulation process at operating points of cylindrical-rotor synchronous generator,four types of isopotential curves are found,and the generator is adjusted according to various isopotential curves.At the same time,the safe operation area formed by various potentials is determined,and the transient operating point of the starting motor is determined in the safe operation area with the use of the binary method.
