SYSTEM AND METHOD FOR STABILIZING ELECTRICAL POWER FOR LOSSES OF ARC IN ELECTRIC ARC FURNACES

摘要

A method and system for stabilizing electrical power for arc furnaces and their power supplies. The method comprises causing a load to absorb power in response to determining a loss of arc event of an arc furnace electrode. After the electrode arc is re-established, power to the load is stopped. The load helps maintain a consistent power consumption during the loss of arc event without significantly changing the power supply output to balance supply with demand. The system comprises a load, and a controller to regulate the amount of power being absorbed by the load. The controller may help expedite re-establishing the electrode arc and help minimize the size of the load. The controller may be part of, or interact with, a furnace power electronic control system.
