The Study And Implement On Technique Of Bus Fed Static Excitation System In Turbogenerator

This paper points out that it is the trend to use bus fed static excitation system to large and medium turbogenerator it has important significance for renovation of old power plant .A detailed study is made for calculation of the main circuit, the automatic voltage regulator and power system stabilizer .Meanwhile, a successful renovation of bus fed static excitation system is get in a 125MW turbogenerator.This device fit for a variety of large and medium turbogenerator.All it quality indexes get to or beyond the stands concerned It has flail functions ,low change of breakdown,flexible and convenient operation .So the shortcomings of traditional exciting system have been overcome.Zhang Minmin (Power System and Its Automation)Directed by Prof Yan Xiangwu...
