摘　　要：电力系统中,同期点的断路器自动准同期并网是目前最常用的并网方式,稍有不慎将有可能造成非同期合闸或同期合闸不成功。通过对金沙江中游流域梨园水电站自动准同期并网方式进行分析研究,找出存在的不足,提出更优的并网解决方法,使自动准同期并网更可靠、稳定、快速。In power system, automatic quasi-synchronous grid connection of circuit breakers at the same time point is the most commonly used grid connection mode at present. If it is faulty, non-synchronous closing or synchronous closing may be unsuccessful. Through analysis and Research on automatic quasi-synchronization grid-connection mode of Liyuan Hydropower Station in the middle reaches of Jinsha River, the paper finds out the shortcomings and proposes better grid-connection solution to make the automatic quasi-synchronization grid-connection more reliable, stable and fast.
