Abstract

An electronic circuit simulator-based approach is presented to improve the simulation speed for the power system transient analysis, where the modeling of SVC (Static Var Compensator) is investigated in a case study. The basic theory of circuit simulation including equation formulation and the numerical algorithm is introduced. Then, the circuit modeling of several power system components such as slack bus, constant power load, synchronous generator, and SVC are investigated respectively. Finally, numerical simulations are conducted on three IEEE test systems. Results demonstrate the applicability of the proposed simulation approach via electronic circuits.

基于电路模拟器的电力系统暂态分析:以SVC为例
为了提高电力系统暂态分析的仿真速度,提出了一种基于电子电路模拟器的方法,并对静态无功补偿器(SVC)的建模进行了实例研究。介绍了电路仿真的基本理论,包括公式和数值算法。然后,分别对冗余母线、恒负荷、同步发电机和SVC等电力系统部件的电路建模进行了研究。最后,在三个IEEE测试系统上进行了数值模拟。实验结果表明了所提出的仿真方法在电子电路中的适用性。
