机组正常启动时，当发电机达到额定转速时，DCS进入AVR。当发电机电压达到额定值时，DCS将进入同步装置。

发电机与电网之间的同步由同步装置自动实现。在同步过程中，AVR和DEH由DCS控制。当同步条件满足时，向发电机断路器发送合闸命令。

同步合闸成功，发电机负荷达到定值后，DCS迅速将压缩机厂用电系统由启动、备用变压器切换到变变压器。

When the unit starts normally, DCS enters the AVR when the generator reaches the rated speed. When the generator voltage reaches the rated value, the DCS will enter the synchronizing device.

The synchronization between the generator and the grid is realized automatically by the synchronization device. During synchronization, AVR and DEH are controlled by DCS. When synchronization conditions are met, a closing command is sent to the generator breaker.

After the synchronous closing is successful and the generator load reaches a fixed value, the DCS quickly switches the compressor plant power system from the starting and standby transformer to the transformer.
