摘要
研究了双PWM变换器结构的微型燃气轮机分布式发电系统的模型,基于下垂特性设计了永磁同步电机侧和网侧变换器的控制系统,可对永磁同步电机转速和变换器直流电压进行控制.利用Matlab建立了微型燃气轮机分布式发电系统的动态模型,对其在不同的负荷情况下进行了仿真.仿真结果表明,在负荷变化情况下,微型燃气轮机分布式发电系统具有较好的稳定性.引入的转子惯性响应能改善系统的动态品质,使整个系统承受较大的负荷冲击.
Micro-gas turbine distributed generation system model with dual PWM converter structure was studied.Permanent magnet synchronous machine side and grid side converters＇ control systems were designed on the basis of the droop characteristics.This control scheme could regulate permanent magnet synchronous machine speed and converter DC voltage.A dynamic model of micro-gas turbine distributed generation was built with Matlab,and simulations were completed under different load conditions.The result has shown that this model has good stability when the load suddenly changes.Rotor inertia response was introduced into this system,which improved the system′s dynamic quality,so the whole micro system can endure a big load mutation.
