電力系統におけるスライディングモード制御の到達条件 Reaching Conditions of the Sliding Mode Control for a Power System
The purpose of this paper is to synthesize the sliding mode control of high speed phase shifters in a power system. The sufficient conditions to reach a sliding plane are given by using an energy-type Lyapunov function. The control scheme is to regard a nonlinearity associated with the power torque-angle curve of AC generator as a variation of parameters based on a linearlized model of the system. By introducing the arbitrary large variation of parameters, a sliding mode controller is applied to the dynamical behavior of this nonlinear system. Moreover, using the Lyapunov function for reaching a sliding plane, the dynamic system becomes asymptotically stable, and thus, the proposed control method is robust control. The validity and usefulness of the controller are tested numerically on a single-machine infinite bus power system.
