分布式并网送电操作流程
英文回答：
Distributed Grid-Connected Power Supply Operation Procedures.
1. Pre-Operation Checks.
Verify the safety of the work area.
Ensure that all equipment is connected and operational.
Check the grid connection parameters (voltage, frequency, power factor).
Confirm that the distributed generators (DGs) are in standby mode.
2. Starting the DGs.
Start the DGs one by one, following the manufacturer's instructions.
Monitor the DG outputs and adjust the power settings as needed.
Synchronize the DGs with the grid.
3. Connecting to the Grid.
Close the grid connection switch.
Monitor the power flow and grid parameters.
Adjust the DG settings to ensure stable operation.
4. Monitoring and Control.
Monitor the grid connection parameters (voltage, frequency, power factor).
Monitor the DG outputs and adjust the settings as
needed.
Control the power flow between the DGs and the grid using power electronics.
5. Fault Handling.
In case of a grid fault, disconnect the DGs from the grid.
Identify and isolate the fault.
Reconnect the DGs to the grid once the fault is cleared.
6. Shutting Down.
Reduce the power output of the DGs gradually.
Open the grid connection switch.
Stop the DGs one by one.

1. 操作前检查。

检查工作区域安全。

确保所有设备连接并运行正常。

检查并网参数（电压、频率、功率因数）。

确认分布式电源（DG）处于待机模式。

2. 启动 DG.
根据制造商的说明逐个启动 DG。

监控 DG 输出，根据需要调整功率设置。

使 DG 与电网同步。

3. 并网。

关闭并网开关。

监控功率流和电网参数。

调整 DG 设置以确保稳定运行。

4. 监控和控制。

监控并网参数（电压、频率、功率因数）。

监控 DG 输出，根据需要调整设置。

使用电力电子设备控制 DG 与电网之间的功率流。

5. 故障处理。

发生电网故障时，将 DG 与电网断开连接。

识别并隔离故障。

故障清除后，将 DG 重新连接到电网。

6. 关机。

逐渐降低 DG 的功率输出。

打开并网开关。

逐个停止 DG。
