Abstract

In this paper a comparative performance of different FACTS-POD devices such as Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), Thyristor Controlled Series Capacitor (TCSC) and Static Synchronous Series Compensator (SSSC) with Power Oscillation Damper (POD) as supplementary controller is analyzed with respect to power oscillation damping capability, system loss reduction and transient stability. For performance analysis the eigenvalue analysis and Time domain simulation results are compared for results validation. The controllers such as power oscillation damper and power system stabilizer (PSS) are tuned according to eigenvalue analysis by considering system stability. The main objective is to reduce the peak overshoot and settling time of inter area oscillations thereby improving power system stability. Here IEEE-14 bus is used as the test system and the simulation platform used is MATLAB/PSAT toolbox. Results shows that by proper tuning of POD with FACTS controllers the power oscillations are damped faster than conventionally used PSS.

PSS与FACTS-POD在电力系统性能提升中的比较研究

本文对比分析了以功率振荡阻尼器(POD)作为辅助控制器的静态无功补偿器(SVC)、静态同步补偿器(STATCOM)、晶闸管控制串联电容(TCSC)和静态同步串联补偿器(SSSC)等FACTS-POD器件在功率振荡抑制能力、系统损耗降低和暂态稳定性方面的性能。在性能分析方面，对特征值分析和时域仿真结果进行了比较，验证了结果的正确性。在考虑系统稳定性的基础上，根据特征值分析对功率振荡阻尼器和电力系统稳定器进行调谐。其主要目的是减少区域间振荡的峰值超调量和稳定时间，从而提高电力系统的稳定性。本文采用IEEE-14总线作为测试系统，采用MATLAB/PSAT工具箱作为仿真平台。结果表明，通过使用FACTS控制器对POD进行适当的调谐，功率振荡的衰减速度比传统的PSS更快。
