SYSTEM FOR OPERATION CONTROL OF INVERTER IN EMERGENCY SITUATION

摘要

A system for inverter operation control in an emergency situation is provided, the system including: an inverter; an upper level controller configured to set a first operation mode for a normal operation of the inverter and a second operation mode in response to an emergency situation of the inverter; and a controller configured to control an operation of the inverter, by stopping an operation of the inverter when a measured voltage value or a measured current value of the inverter satisfies a first condition when the first operation mode is set, and by maintaining an operation of the inverter even when a measured voltage value or a measured current value of the inverter satisfies a first condition when the second operation mode is set.
