摘要
发电机与系统之间的准同期并列应严格满足电压、频率、相位等条件。分析了电压差、相位差及频率差存在的情况下,冲击电流的性质及冲击电流对发电机和系统的影响。基于上述分析结果及自动准同期装置和合闸断路器相关参数,针对实例对同期闭锁继电器闭锁角进行了整定计算。
For the quasi-synchronization paralleling of the generator with the system,some conditions,such as voltage,frequency,phase and etc.,must be satisfied seriously.Considering that the voltage difference,the phase difference and the frequency difference are existed,the characteristics of the impact current and the influence of the impact current on the generator and the system were analyzed.Based on the result of above analysis and the related parameters of the automatic quasi-synchronization device and the closing breaker,aiming at a practical example,the setting calculation of the blocking angle of the synchronization blocking relay was carried out.
