摘要(Abstract):
分析了发电机励磁系统强励功能和作用,发电机强励的动作过程及过励限制、顶值限制和相关保护的配合方式。对浙江电网发电机励磁系统强励核查过程中发现的主要问题进行了分析,提出发电机实际强励能力的核算方法和强励功能核查工作的重点,以确保发电机强励功能的实现。
This paper analyzes the forced excitation function and effect of the generator excitation system,forced excitation process and method of cooperation between over-excitation limitation,ceiling limit and relative protection.Through the analysis on the main problems found in the forced excitation function checkup of generator excitation system in Zhejiang grid,this paper brings forward the check method of actual forced excitation capability of generators and the key points of the checkup to ensure the achievement of generator forced excitation function.
