OVERCURRENT PROTECTION METHOD, CONTROL SYSTEM AND STORAGE MEDIUM FOR BRIDGE ARM CURRENT

摘要

An overcurrent protection method, control system and storage medium for bridge arm current of a flexible direct current transmission system. The method comprises: acquiring a bridge arm current (S101); processing the bridge arm current to obtain a current effective value and a current instantaneous value (S102); and protecting the bridge arm current when the current effective value is greater than a first set threshold and the current instantaneous value is greater than a second set threshold (S103).
