摘要：

An Automatic Voltage Control (AVC) system for the thermal power plant is proposed to ensure the safety, efficiency and economy of the grid voltage. The bus bar voltage can be adjusted on the existing platform of plant wide optimal load distribution system to improve the equipment utilization. Through the dynamic identification system impedance, conversion voltage and reactive online, and fix adaptive regulator parameters, carry out fast and zero error output adjustment. Based on the distribution of the strategy of reactive power the bias adjustment algorithms, carry through reactive power coordination control between units, and realize the self-regulation of bus bar voltage. For the actual circumstance, the hardware and software of the system are designed, the technical problems of data acquisition, excitation modification, running mode, locking protection are elaborated too. The system design is novel, construction-save, powerful function, stable and reliable, and it has the very good reference and popularize value.
