A variable structure controller for Static var Compensator (SVC) which can improve powerAngle stability of power system and local voltage characteristics of SVC is proposed.
Laser compared to other lights has the characteristics of higher power, less divergence Angle, better monochromaticity, shorter light pulse and continuously tunable spectrum output.
激光与其它光相比,具有功率高、发散角小、单色性好,输出的光脉冲窄和输出光谱可连续调谐的特点。
