一种虚拟同步发电机自适应阻尼补偿方法
An adaptive damping compensation method for virtual synchronous generators
摘要
Abstract
To solve the problem that the system inductance has the equivalent negative damping effect on the virtual syn-chronous generator control system,an adaptive damping compensation method is proposed in this paper.Firstly,based on the virtual synchronous generator control technology,the dynamic electromagnetic equation and dynamic small signal mod-el of the system are established through dq transformation and small signal analysis.Then,the synchronous moment coeffi-cient and equivalent damping coefficient are decomposed by electromagnetic torque deviation.Finally,according to the a-nalysis of the generation mechanism of equivalent negative damping,a damping compensation module with system frequen-cy and virtual impedance as adaptive control variables is added to the active power-frequency regulator to realize the adap-tive compensation for the damping of virtual synchronous generator.Through MATLAB/Simulink simulation,a comparison of the results obtained by the proposed method with the results obtained by the traditional virtual synchronous generator control method and the virtual impedance compensation method is made,which shows that the adaptive damping compen-sation method proposed in this paper has stronger stability and faster response speed,thus verifying the effectiveness of the proposed method.关键词
