| Abstract: | 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 rela- tive 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 fox-ward the check method of actual forced ex- citation capability of generators and the key points of the checkup to ensure the achievement of generator forced excitation function. |
