[Abstract]:The accuracy of measurement in the actual operation of power transformer field is related to the safe and stable operation and fair measurement of power system. In this paper, multi-winding secondary load coordination optimization technology and DC bias magnetic evaluation and suppression technology are proposed to improve the accuracy of measurement under the operation of traditional transformer, and the temperature adaptive technology is used to improve the accuracy of measurement. The reciprocal optical circuit and four-state closed-loop control technology can improve the accuracy of the electronic transformer in operation, and finally realize the overall improvement of the measurement accuracy in the field operation of the power transformer.
