Abstract

As renewable energy has become a greater part of the power system; it is important to analyze how its integration to grid affects its stability. With the installation of DFIG, the transient instability of power systems is elevated using an Automatic Voltage Regulator (AVR) and Power System Stabilizer (PSS) installed on synchronous generators. A similar kind of approach is adopted in this paper to analyze and investigate the stability of a Western System Coordinating Council (WSCC) 9-bus and 68-bus system while integrated with a wind farm. The stability is evaluated in terms of a parameter called transient stability index or TSI. An impact of varying load/generation near faulted bus is investigated till the system go unstable. Further, TSI is observed with and without AVR and PSS connected to synchronous generators. It has been seen that by using an AVR and PSS improvement in TSI has been recorded. Above investigations are realized through implementation on Power System Analysis Toolbox or PSAT.

基于PSAT的风电场综合电力系统暂态稳定分析

随着可再生能源在电力系统中的比重越来越大;分析其与电网的结合对其稳定性的影响是十分重要的。在同步发电机上安装自动调压器(AVR)和电力系统稳定器(PSS)，提高了电力系统的暂态不稳定性。本文采用类似的方法对西部系统协调委员会(WSCC) 9总线和68总线系统与风电场集成时的稳定性进行了分析和研究。稳定性是根据一个称为瞬态稳定指数或TSI的参数来评估的。研究了故障母线附近变负荷/变发电量对系统的影响，直至系统不稳定。此外，在有和没有AVR和PSS连接到同步发电机的情况下观察TSI。已经看到，通过使用AVR和PSS改善TSI已被记录。上述研究是通过电力系统分析工具箱(PSAT)的实现来实现的。
