| Abstract: | In this paper, the mathematical model of generator excitation system, governor, rectifier and other equipment is built based on the complex control parameters matching of shipboard DC integrated power system. The small-signal stability analysis based on state space equation is performed on the system. By changing the parameters of the governor PI parameter, the relationship between the governor PI parameter and the voltage stability is obtained. Then the simulation model of the system is built in Digsilent/Power Factory to verify the validity of the conclusion, which provide support for the control parameter design of the system. |
