摘　　要：本文采用PIC16F877和FPGA设计自动准同期装置,采用硬件电路消除在频率、相角差信号转换时由于硬件灵敏度产生的误差,在电压信号测量时采用AD536和ADC测量电压值。该装置自动测量并显示发电机及系统的电压、频率和相角差,并以恒定越前时间发出合闸脉冲,自动完成发电机并列操作。In this article, uses PIC16F877 and FPGA designs the automatic quasi-synchronization device, Uses the hardware electric circuit eliminates in the frequency and the phase angle difference transformation time the hardware sensitivity to produce error, uses AD536 and the ADC survey voltage value. This equipment surveys automatically and demonstrated the generator and the system voltage, the frequency and the phase angle difference, and send out the switch on pulse by the constant anticipating time, completes the generator parallel operation automatically.
