摘要
在解除管制的电力系统中,电力需求的增加导致输电线路超出其传输限制,并导致违反其限制,从而导致线路过载。传输系统的可用传输能力(ATC)是对给定时间内系统未利用能力的度量。ATC的计算对于输电系统的安全运行非常重要,本文着重介绍了采用晶闸管控制串联电容器(TCSC)、晶闸管控制相角调节器(TCPAR)、静态无功补偿器(SVC)等FACTS器件来提高输电系统的功率传输能力。采用灵敏度法将这些FACTS器件优化放置在传输系统上。提出了一种利用Power World Simulator 17软件对改进型IEEE-14总线系统进行ATC增强的方法。
Enhancement of ATC in a deregulated power system by optimal location of multi-facts devices
Increased electric power demand in a deregulated power system causes transmission lines to be driven beyond their transfer limits and causes violation of their limits which results to over load of lines. Available Transfer Capability (ATC) of a transmission system is a measure of unutilized capability of a system at a given time. The computation of ATC is very important to operate the transmission system more secure and the paper focuses on increasing the power transfer capability using FACTS devices like TCSC (Thyristor Controlled Series Capacitor), TCPAR (Thyristor Controlled Phase Angle Regulator), SVC (Static Var Compensator). These FACTS devices are optimally placed on transmission system using Sensitivity approach method. The proposed method is to enhance the ATC on Modified IEEE-14 bus system Using Power World Simulator 17software.
