一种新型的FACTS控制设备实验与性能测试平台

摘要

本文构建了一种新型的FACTS控制装置实验与性能测试平台。以可控串补（TCSC）的接入为例,该仿真平台由TCSC控制装置与电力系统全数字实时仿真装置（ADPSS）接口而成。仿真平台用机电暂态模型对大电网建模,用电磁暂态模型对TCSC及其所在的线路建模,通过物理接口箱将TCSC控制装置接入到仿真平台。TCSC控制装置采集功率放大器的输出,根据内置的控制策略发出TCSC的控制信号。ADPSS根据接收的控制信号控制晶闸管模型的状态。该仿真平台不需要对大电网进行任何等值就可以研究FACTS接入后对电力系统的影响。本文给出了TCSC的阻抗控制、潮流控制及阻尼功率振荡控制的实验结果。实验结果表明,本文构建的实时仿真平台是有效的,可以用于研究FACTS装置对电力系统的影响及检测FACTS控制设备的性能。%A novel platform for experimenting and testing FACTS controllers is constructed.Take TCSC as an example,the platform is constructed by interfacing a TCSC controller to the ADPSS.The majority of power system is modeled using electromechanical models,while TCSC and the line it inserted are modeled using electromagnetic models.TCSC controller is connected to ADPSS using a physical interface box.TCSC controller measures the outputs of power amplifier,and output control signals according to its control strategy and the measured signals.ADPSS adjusts the states of thyristors on receiving the control signals.The platform can be used to research the effects of FACTS controllers to the power system without any equivalence of the vast power grid.Experimental results of reactance control,power flow control,power oscillation damping control with TCSC controller are presented.The experimental results show that this platform is valid;it can be used to study the effects of FACTS to power system and test the performance of the FACTS controllers.
