With the rapid development of power grid, large capacity units are continuously put into operation, which makes the small interference. This paper analyzes the influence of different regulation modes of AC exciter excitation system on the performance of generator excitation control system, demonstrates that PID excitation regulation can effectively improve the quality of excitation control, and simulation test is an effective measure to adjust the parameters of excitation system.
The basic principle of turbogenerator stator core magnetization test is introduced, aiming at the overheated condition of stator core during magnetization test of No.1 generator in Yingkou Power Plant of Huaneng International Electric Power Co.,Ltd., the causes of hot spots in the core during the test are analyzed, the test, inspection and treatment process are introduced,after treatment,the stator core of the generator can be operated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
