Study and Development of Marine Power Station Simulator

The paper discussed how to develop simulator of marine power system which is a kind of power system making up of several generators and AC&DC power supply, including general design and simulation mathematical model. According to characteristics and operational requirements of marine power system, a complete set of mathematical models of marine power system were established, which included turbine generator models, diesel generator models, AC&DC converter unit models, storage battery models and AC&DC network models, etc. Mathematical model of the generators as PQ node or balance node in power flow algorithm and grid frequency of marine power system, were also considered in the model. Some simulation experiments for mathematical model of marine power system were done, the steady-state results accorded with the log of the marine power system and the dynamic curves had reasonable trends.
