并网型风电场动态无功补偿方案的仿真

Simulation of Dynamic Reactive Power Compensation Scheme of Grid-Based Wind Farm

目前对于并网型风电场内无功不足进行无功补偿普遍采用的方式是在异步风力发电机端并联电容器组。随着电力电子技术的迅猛发展,该补偿方式已经显现出明显弊端,将动态无功补偿装置应用到风电场中已经成为一种必然趋势。给出了风电机组模型、动态无功补偿装置模型;建立了并网风电场的仿真模型;将SVC和STATCOM这两种动态无功补偿装置分别应用到风电场中并进行了仿真对比。

At present, for lack of grid type wind farm to compensate reactive approach was widely used in the asynchronous wind generator terminal shunt capacitor banks. With the rapid development of power electronic technology, such compensation has begun to show obvious defects, the dynamic reactive power compensation devices （SVC and STATCOM） applied to the wind farm has been become an inevitable trend. The wind turbine model was given, dynamic reactive power compensation device model ; a simulation model of wind power grid was established; the two kinds of dynamic reactive power compensation devices （SVC and STATCOM） were applied to the wind farm and simulation in the comparison.
