摘　　要：从水轮发电机同期并列条件出发,以尽量减小水轮发电机组同期合闸瞬间冲击电流为出发点,结合自动准同期工作原理,对同期装置主要参数,包括相角差、频率差、电压差、调压速率、调速速率进行整定分析,整定结果可靠,确保了同期并列时水轮发电机组和电力系统的稳定性。Based on the synchronous parallel conditions of hydro-generators,settings of major parameters,including phase angle difference,frequency difference,voltage difference,voltage regulation rate,and speed regulation rate in the synchronizing device were analyzed in accordance with the automatic quasi-synchronization principle with a starting point of minimizing the instantaneous surge current of the synchronous closing of hydrogenerator sets.Setting results were proven to be reliable,safeguarding the stability of the hydro-generator unit and the power system in the synchronous parallel process.
