多机系统TCSC非线性PID控制器研究

TCSC阻抗控制是实现TCSC其他控制功能的基础,而系统层控制在一定的控制策略下对电力系统的目标参数进行及时有效地反映.结合非线性控制和PID控制的优点,采用非线性控制作为系统层控制,PID控制作为中层控制,设计了控制器,其控制策略采用本地信息,不依赖于系统的精确模型.在Matlab/Simulink仿真环境下搭建两区域四机系统进行仿真.结果表明,该控制器在提高系统暂态稳定性方面有很好的作用.

Study on Nonlinear PID Controller for TCSC in Multi-Machine System

TCSC impedance control is the foundation of other control functions of the TCSC,and the system layer controller can show exactly the change of the objective parameters based on uhe given control schemes.This paper takes the advantage of both nonlinear and PID controller and designs a compositive controller using the nonlinear controller in the system layer and the PID controller in the middle layer.It uses the local information and is not dependent on the system's accurate model and parameters.The Matlab/Simulink software is used to build the detailed model of the TCSC and the two-area four-machine TCSC system.The simulation results indicate the good performance of the TCSC controller on power systems.
