摘要
本文研究并分析了TSC的基本原理及其九区图控制法,指出九区图控制法的缺陷。结合无功控制的实践经验,研究了基于模糊控制的TSC型动态无功补偿控制器。该模糊控制器采用了2输入单输出的结构。模糊推理系统对电压--无功平面进行模糊分区,减少了由于测量值的微小变化引起运行点在相邻区域之间的振荡,引起不必要的电容投切或电压调节。通过MATLAB建立了模糊控制系统的仿真模型,仿真结果验证了该算法的有效性,增加了系统的稳定性,减少电容器动作的次数。
In this paper, study and analyze the basic principles of the TSC and its＇ nine-zone controlling method, point out the defects of the nine-zone controlling method. With the help of reactive power control of the practical experience, research the controller of the TSC dynamic reactive power compensation system based on fuzzy control. In the fuzzy system, the controller structure is twoinput and single-output. The voltage-reactive power plane was divided into a fuzzy area by the fuzzy inference system, so as to reduce the shocks of the adjacent running point because of the small changes in measurement and the unnecessary capacitance switching or voltage regulator. The simulation model of fuzzy control system is established by the MATLAB software, the results show the effectiveness of the algorithm, increasing the stability of the system, reducing the number of the action of capacitors.
