摘要

根据单轴微型燃气轮机和永磁同步发电机特点

建立了使用双脉宽调制(PWM)换流器的微型燃气轮机发电系统动态仿真模型。为控制交直交变换器中电容电压和提高微型燃气轮机控制系统响应速度

模型中采用了参考负荷功率的PWM恒压控制方式。与采用二极管整流装置的微型燃气轮机系统相比

该模型可对永磁同步电机转矩和整流器直流电压进行协调控制

使得系统充分利用负荷功率变化的信息。仿真结果表明，该模型能够在负荷发生较大变化时满足负荷电压和功率的需要

并能够减小变换器间直流电压波动以及对直流电容的容量需求

使整个微型燃气轮机发电系统承受负荷冲击的能力大大提高。

Abstract

Based on an analysis of the characteristics of microturbine and permanent magnet synchronic generation

a simulation model of the singleshaft microturbine generation system with double PWM converters is made. In order to maintain the DC voltage and increase the response speed of microturbine

a constant voltage control method with load power tracking is used. The model can fully utilize the information about load power changes to control electromagnetic torque and DC voltage. The simulation results show that the model of microturbine with PWM structure can maintain loads voltage and satisfy power demand in the course of load changes

reduce the variation of DC voltage and value of DC capacitor between rectifier and inverter

and greatly improve the ability of bearing the load power impact.
