摘　　要：随着风电装备的大规模普及,作为风电系统接入电网的关键接口,并网逆变装置对电网系统的影响越来越显著。本文基于同步发电机数学模型,提出一种基于虚拟同步发电机原理VSG(Virtual Synchronous Generator)的等效功率平抑及频率补偿方法,通过110 kw风力发电机组的试验样机对该方法的有效性进行了试验验证,结果表明:虚拟同步发电机控制技术使得电网接口具有与同步发电机相同的优良控制性能,为电网系统提供稳定的惯性和阻尼,提高大规模风电并网系统的稳定性。With the massive popularity of wind power equipment,wind power system as access to key interfaces grid and grid-connected inverter grid system impact means more and more significant. Based on a mathematical model of synchronous generator,proposed an equivalent power of synchronous generator on virtual principles（Virtu-al Synchronous Generator,VSG）of stabilizing and frequency compensation method,the effectiveness of the method prototype test 110 kW wind turbines were experimental verification,the results showed that virtual synchronous generator control technology allows that synchronous generator grid interface has the same excellent control perfor-mance,inertia and damping,provide a stable grid system,and improve the stability of large-scale wind power grid system.
