Problems with connecting the generator to the grid?
Thread Content
May I ask everyone, when a generator is connected to the grid and the voltage on the side to be connected is lower than the voltage on the system side, will this cause a large current surge in the system?
Grid connection requirements: The voltage, frequency, and phase must be consistent. This concept of consistency is relative, as it’s impossible for them to be exactly the same; rather, it’s sufficient that they fall within acceptable error ranges.

It will not have a significant impact on the system, so it can be ignored. However, impacts on the generator can easily lead to accidents.
Grid connection requirements: identical voltage, identical frequency, identical phase. The term \"identical\" is relative, as it’s impossible for these values to be exactly the same; they just need to fall within acceptable error ranges. Do you perform grid connection manually or automatically?
1# men*aoyong generator grid connection is divided into quasi-synchronous and self-synchronous methods. The quasi-synchronous requirement is that before grid connection, the voltage and frequency must be adjusted to be within the specified range, and automatic monitoring should be enabled. With quasi-synchronous conditions, the switch is automatically pulled into synchronization. Options with significant impact are generally not chosen. Do not load the generator when connecting it to the grid.
