SVC与发电机励磁无源协调Backstepping控制

Coordinated Control for SVC and Generator Excitation Based on Passivity and Backstepping Technique

采用无源协调性的思想方法,对发电机励磁和静止无功补偿器(SVC)同时进行协调控制和调节。利用Backstepping的设计方法得到SVC的控制设计,并根据协调无源性的特点,得到了发电机励磁的控制,使整个系统的功角和电压达到双重稳定的效果。由于整个设计过程没有采用任何线性化的处理,充分利用了系统的非线性,保证了本文所提出的控制律在非线性系统中的适用性。利用单机无穷大系统进行研究,仿真结果证实了本文所提出的控制律的有效性和正确性。

The SVC and excitation controls for generator are proposed to make rotor angle and voltage stable by the coordinated passivity techniques. The SVC control is designed by the Backstepping technique, and the excitation control for generator is proposed based on the coordinated passivity. Since the whole system fully utilizes the nonlinear characteristics of the system without any linearization technique, the applicability of the control law can be ensured in the nonlinear system. The simulations of single machine infinite bus system can prove the validity and efficiency of the control law in this paper.
