摘　　要：该文给出了采用实用信号调制的SVC综合非线性控制器,对SVC在交直流混合系统中的应用进行了数字仿真研究,比较了SVC不调节时、采用常规电压调节时、采用电压型非线性控制时和采用信号调制型非线性控制时的不同控制效果。研究表明,信号调制型SVC综合非线性控制器,能够给系统提供较强的阻尼,从而提高了整个交直流混合系统的暂态稳定性。The synthetical nonlinear SVC controller modulated by practical signals is provided in this paper. The application of SVC controller in AC and DC hybrid system is analyzed in detail by simulation. The control effects of the following four kinds of conditions are compared, i.e. SVC without regulation, regular SVC voltage controller, nonlinear SVC voltage controller and the signal-modulating type synthetical nonlinear SVC controller. The results show that the signal-modulating type synthetical nonlinear SVC controller can provide higher damping to the system,so as to enhance the transient stability of the AC and DC hybrid system.
