【 摘 要 】

When the balance of power system is broken, the frequency of power system will be deviated. Induction motors are mostly used in industry. Frequency is closely related to the change of speed and output power. Firstly, this paper focuses on the analysis of the mathematical model of the inter-regional tie-line and deduces the Laplace transform of the power variation of the tie-line. The physical model is established to analyse. The fluctuation of the two regions and the interconnected power grid is obtained. The operating point will change in the case of disturbance. The relationship between the switching power deviation of tie-line and the disturbance position point. Through the simulation of the classical two-zone model, the simulation effect of the PID controller is better than that of the conventional controller. The control effect is remarkable, which provides a certain basis for later research. The ideal adjustment parameters of the PID controller are obtained by trial-and-error method. The dynamic and robust performances of the AGC system are further verified by simulation.
