摘　　要：发电机准同期并网时,机组侧与系统侧的电压、频率及角差必须满足允许并网条件。首先阐述了并网参数对同期的影响,然后针对云南某大型水电机组监控系统同期装置并网时间过长的现象,进行了原因分析,并提出了相关解决方案,对其他同类型机组的同期操作有一定的参考意义。When the generator is quasi synchronous connected to the grid,the voltage,frequency and angle difference between the unit side and the system side must meet the allowable grid connection conditions.The impact of grid connection parameters on synchronization is introduced.The synchronization time of the monitoring system for a large hydroelectric unit in Yunnan is too long.In response to this issue,a cause analysis is conducted and relevant solutions are proposed,which has certain reference significance for the synchronous operation of other similar units.
