COMBINED MONITORING ALGORITHM POWER AND ENERGY LOSSES IN TRANSFORMERS ACCORDING SYNCHRONIZE HIGH-PRECISION MEASUREMENTS

Abstract

This paper discusses the possible ways of monitoring the power loss and energy loss in transformers in the introduction of the concept of digital substation. The use of high-precision synchronized measurements of the load flow allows to calculate the power loss or for the equivalent circuit, either directly on the measurement, the oper- ating parameters of the transformer windings. Based on analysis of the errors of each of the methods proposed combination algorithm selects one of the methods depending on the load factor of the transformer.
