Design of Generator Synchronizing Device Based on PIC16F877 and FPGA

In order to improve the celerity, veracity and security of the generator paralleling operation, a new type of generator automatic quasi-synchronizing device based on PIC16F877 and FPGA (Field Programmable Gate Array) was studied in this paper. The hardware and software designs were introduced. The device adopted PIC16F877 as main controller and FPGA as assistant controller which realized the control of the output impulse width and displayed the signals of the output actions. The excellence of the mix design is that two advantages are reinforced. The hardware circuit is simple and the reliability of the system is high, so that the generator realizes quasi-synchronizing quickly and veracity.
