摘要

虚拟同步发电机（virtual synchronous generator

VSG）传统固定转动惯量策略存在动态响应与稳态性能的矛盾

且容易出现功率振荡问题

为此提出一种基于自适应分段转动惯量的虚拟同步发电机控制策略。通过分析振荡机理

动态划分惯量调节区间

在功率波动剧烈时

降低转动惯量提升控制速度;当功率波动具有放缓的趋势以后

增加转动惯量提升稳定能力。通过该优化设计

VSG在多种运行模式下均表现出良好的参数鲁棒性

有效抑制了有功功率的低频振荡

提高了暂态过程调控精度。最后

MATLAB/Simulink仿真验证了所提方法的可行性与正确性。

Abstract

To address the contradiction between dynamic response and steady-state performance in traditional fixed moment of inertia strategies of virtual synchronous generators (VSG) and the power oscillation problems

a virtual synchronous generator control strategy based on adaptive segmented moment of inertia is proposed. By analyzing the oscillation mechanism

the inertia adjustment interval are dynamically divided. When power fluctuations are severe

the moment of inertia is reduced to improve control speed. When power fluctuations have a slowing trend

the moment of inertia is increased to improve stability. Through this optimized design

VSG exhibits good parameter robustness in various operating modes

effectively suppressing low-frequency oscillations of active power and improving the accuracy of transient process control. Finally

MATLAB/Simulink simulation verifies the feasibility and correctness of the proposed method.
