摘要

为了保持电力系统的稳定，应在尽可能短的时间内消除频率波动。提出了一种线性二次型调节器(LQR)与振动补偿器(VC)相结合的鲁棒控制方案，用于单区发电系统负荷变化引起的频率波动的鲁棒控制。LQR控制器用于补偿误差偏差，增广VC用于抑制频率波动。为了证明所提出的LQR- vc控制器的有效性，将其性能与自动生成控制(AGC)方案、现有PID和LQR控制器进行了对比。

Compensation of Frequency Fluctuation in a Single Area Power System Using LQR-VC

To maintain the power system stability frequency fluctuation should be eliminated within the shortest possible time. A new control scheme combining linear quadratic regulator (LQR) along with a vibration compensator (VC) is proposed in this paper for the robust control of frequency fluctuation due to load variation in a single area generating system. The proposed LQR controller is used for compensation of error deviation and the augmented VC to damp the frequency fluctuation. To demonstrate the effectiveness of the proposed LQR-VC controller its performance is contrasted with the automatic generation control (AGC) scheme, existing PID, and LQR controller.
