| 摘 要： | 本文根据微电网对逆变器性能的要求,借鉴同步发电机的经典数学模型,设计了一种适用于微电网的逆变器控制模型(虚拟同步发电机)。该逆变器具有功率、电压、频率调节的功能,能够根据电网自身以及负荷的变化合理调整输出以满足系统的稳定性要求。在MATLAB/Simulink环境下搭建了该系统的仿真模型,仿真结果验证了该方法的正确性和合理性。

| Abstract: | A new inverter based on the model of synchronous generator(which is called virtual synchronous generator) is presented.The inverter has the fuction of controlling power and modulating frequency and voltage,which meets the need of microgrid.It can modulate the output reasonably to meet the stability requirements of the power system.This scheme has been proved with MATLAB/Simulink in the end. |
