十二相同步发电机降阶等效模型研究
Study on equivalent reduced model of twelve-phase synchronous generator
摘要
Abstract
The twelve-phase synchronous generator-rectifier system can offer high-quality DC power, but its mathematical model is quite complicated, which makes the analytic computations difficult. To solve this problem, the equivalent three-phase reduced model and the state-space average model are derived to simplify the original model and to promote the computation efficiency. The equivalent three-phase model can be applied under both large and small disturbances, and is validated by simulations on suddenly applying and shedding loads, adjusting of excitation voltage, and short circuit. The state-space average model is applied under small disturbance to make the computation more efficient, and lays the foundation for theoretical analysis of the generator-rectifier system. The equivalent three-phase model and the state-space average model are built in PSCAD. The large and small disturbances on the models are simulated and the results are compared, and the correctness of the simplified models is validated.关键词
