Title:
TRANSFORMER BANK CONTROLLING SYSTEM
Document Type and Number:
Japanese Patent JP3211355
Kind Code:
B2
Abstract:
PURPOSE: To reduce the capacity and excitation loss and improve the operating efficiency of the transformer of a power receiving facility which supplies electric power to loads born by a plurality of transformer banks so as to reduce the cost, occupying space, energy consumption, and redundant operations of the facility by introducing fuzzy control to the facility.
CONSTITUTION: By respectively comparing the inferred values of the operating number of transformers and overload operating states of cause items calculated by means of a fuzzy inference section 11 from phenomenon items composed of the moving average of the load currents of the transformers indicating the state of a load calculated by means of a moving average calculating section 10 which calculates the moving average, temperatures detected by means of the winding temperature sensors 4a and 4B of the transformers, and the temperature detected by means of an outside-board temperature sensor 8 with set values, the number of operated transformers is controlled and an overload alarm is issued.
