The situation of home manufacture of brushless excitation system is introduced essentially in this paper.The production of brushless excitation system devices with high initial response for large turbogenerators in China has achieved advanced level in the world. The more thoroughgoing theoretical study on increment of dynamic and transient response speed for excitation system is made, and the technic-effective and economic-feasible method for th's increment are given. The given mathematical model of brushless excitation system is exact to be verified by its test and operation at power stations,it can be used as scientific basis for choosing parameters of brushless excitation system in design. Meanwhile. principle and method for choosing parameters of excitation systems' PSS are discussed also, and they can be used as basis for commissioning and successful operatin of the PSS. The complete methods for works check test of brushless excitation system are presented, which provides check means for high-qualitative manufacturing brushless excitation system in the works.Home manufacture of AVRs and devices for testing HIR excitation system at works are introduced briefly.
