摘要

针对基于模块化多电平换流器（modular multilevel converter

MMC）的多相风力发电系统中

传统MMC因缺乏转动惯量导致的频率调节能力不足及功率振荡问题

设计基于运行工况的参数动态调整策略

实现有功-频率控制参数的自适应匹配

有效抑制暂态过程中的功率振荡与频率波动

基于MATLAB/Simulink平台搭建仿真模型。仿真结果表明

在动态响应速度、频率稳定性等方面所提策略相较于传统控制方法均有更优的效果。

Abstract

Focusing on the multiphase wind power generation system based on modular multilevel converter (MMC)

this paper studies the insufficient frequency regulation ability and power oscillation caused by the lack of moment of inertia of traditional MMC

and proposes a dual-dimensional improved VSG control strategy. The frequency output characteristics are optimized through the real-time compensation mechanism of active power deviation. A parameter dynamic adjustment strategy based on the operating conditions is designed to realize the adaptive matching of active power-frequency control parameters

which effectively suppresses power oscillation and frequency fluctuation in the transient process. A simulation model is built based on MATLAB/Simulink platform. The simulation results show that the proposed strategy has better effect in terms of dynamic response speed and frequency stability compared with the traditional control method.
