Abstract

One of the major aims of system operator is to maintain system parameters within feasible operational margin. During certain period of time in a day-load changes very rapidly, especially when it tends to increase, a generalized voltage decrement and stressed conditions for reactive power sources occurs. Maintaining Voltage profile under varying load conditions is need of today under unpredictable load scenario. The work embedded highlights expediency of STATCOM for improving voltage profile of power system under perturbations while providing necessary reactive power support. Performance evaluation is supported by simulation results on WSCC 3-generator 9-bus system under different loading conditions using MATLAB based software tool PSAT.

基于STATCOM的重构电力系统电压分布管理
系统操作员的主要目标之一是将系统参数保持在可行的运行裕度之内。在一天中的某一段时间内,负荷变化非常迅速,特别是当负荷有增加的趋势时,会出现广义电压衰减和无功电源的受力状况。在不可预测的负载情况下,维持不同负载条件下的电压分布是当今的需要。嵌入式工作突出了STATCOM在提供必要的无功支持的同时,改善扰动下电力系统电压分布的便捷性。利用基于MATLAB的PSAT软件对WSCC 3-发电机9-母线系统在不同负载条件下的仿真结果进行了性能评价。
