System Program Design for Micro Generator Set: Gasoline Engine — PMSG — Thyristor Rectifier With Low Cost and High Reliability

The integrated power system is a kind of important meaning power structure in many situations because of its highly efficient and power density. While the system is concluded by prime mover, battery, generator motor, rectifier and inverter, the cost and the reliability are the key matter. Especially, for the micro generator set, the matter is more serious. Firstly, the prime mover of micro generator system is hard to chose and match the generator motor. Secondly, the winding of generator motor is hard to design for satisfying kinds of power requires. Thirdly, the reliable power convertor should be small and efficient. This paper discusses the system program design for micro generator set: Gasoline Engine – three phase permanent magnet synchronous generator (PMSG) – thyristor rectifier with low cost and high reliability. It mainly focusses on the program of prime mover, motor winding and rectifier. Consider the structure, this paper also analyzes the match between the three parts and simulate the effects. Last, this paper simulates the designed generator system program and test the effect and feasibility.
