Configuring the Procedure in the Event of a Generator False Start

Operating procedure if a generator false start is detected:

If the Sunny Island detects a generator false start (e.g., voltage too high), the Sunny Island does not connect the stand-alone grid to the generator. If there is another request for the generator after the minimum stop time, the Sunny Island attempts to start the generator. If the Sunny Island detects a false start on numerous occasions and the number of failed attempts exceeds the maximum value, the Sunny Island switches into error status. The Sunny Island attempts to restart the generator upon expiry of the Idle period after generator fault.

Single cluster systems:

The generator management classes a line conductor fault on the main device as a generator failure. All Sunny Island inverters disconnect the stand-alone grid from the generator. The generator management treats a fault on the line conductor of the subordinate device as a line conductor fault. The subordinate device disconnects only the affected line conductor from the stand-alone grid. The slave switches the stand-alone grid to the generator again if the faulty line conductor is in the valid range.

Procedure:

The basic procedure for changing operating parameters is explained in another section ( > Changing Operating Parameters).
