The hydrogenerator has reached grid connection conditions when connected to the grid, but there is n

Nowadays, automatic network connection is adopted for network connection. When the grid connection device detects that it can automatically connect to the grid, it will automatically connect to the grid and then simply close the circuit breaker. I don't know how your power plant is connected to the grid! If there is no response when closing the circuit breaker after the device connected to the network detects the signal that it can be connected to the network, check whether the circuit breaker is normal, whether the knife switch is normal, if the low voltage side and the high voltage side of the main output transformer are open circuits, etc.
