摘要

建立了包含风力机和异步感应发电机在内的风电机组的整体动态数学模型;以建立的数学模型为基础确立了接入无穷大系统的风电场仿真模型。给出了一种新型的基于直流侧电容电压控制和系统无功电流反馈控制的算法对静止无功补偿器（STATCOM）实行控制，以渐变、随机和阵风这3种风速情况为例对STATCOM的补偿特性进行了仿真分析，并将其补偿效果与晶闸管投切电容器（TSC）进行了比较。仿真结果表明，与TSC相比，STATCOM在补偿过程中能迅速稳定地跟踪无功的变化，并且补偿时无明显的冲击电压和电流。

Abstract

This paper establishes a dynamic model for wind turbine-generator unit， including the wind-turbine and asynchronous induction generator. Based on the proposed dynamic model， a model of wind farm connected with an infinite system is constructed. Based on the DC voltage control as well as the feedback control of reactive current， a new control algorithm is presented for STATCOM. Considering three cases， i.e.， the wind speed ramp， the wind gust and the wind disturbance， the numerical simulations on compensation characteristics of STATCOM are studied. The compensation effects between TCSC and STATCOM are compared. The simulation results illustrate that STATCOM can track the changing of reactive power quickly and stably in the procedure of reactive power compensation comparing to TCSC， and there are no serious inrush currents or over-voltages.
