Intelligent on-line analysis system for transformer operation

Abstract

The invention relates to economical operation mode research and operation suggestion prediction of a transformer, in particular to an intelligent on-line analysis system for transformer operation. Thesystem comprises an equipment tree, a transformer parameter configuration module, a load inquiry module and an analysis display module. The load data of the actual operation of the transform is utilized to intelligently forecast the load condition of the transformer in the future, and finally, the economic operation report of the transformer and the operation mode suggestions of the transformer in different time periods are given, a convenient intelligent means for mastering the economic operation situation and trend of the transformer is given, and the economy of the transformer operation inthe distribution network can be effectively improved and the overall electric energy loss of the distribution network system is reduced.

Description

Technical field [0001] The invention relates to the economic operation mode research and operation suggestion prediction of transformers, in particular to an intelligent online analysis system for transformer operation. Background technique [0002] Transformer is a key equipment in the power supply system. Its main function is to boost or step down to facilitate the reasonable transmission, distribution and use of electric energy. It has an important impact on the form of the main wiring of the substation and its reliability and economy. [0003] In recent years, with the rapid development of the national economy, the electricity consumption of some large factories, enterprises, shopping malls, etc. has increased day by day. As a result, the economic operation of the power grid has received increasing attention. According to statistics, the total loss of transformers in my country accounts for about 10% of the total power generation of the power system and 30% of the total power l...

Problems solved by technology

[0005] In order to reduce the power loss during the operation of the transformer and improve the transmission efficiency of the system, the traditional economic operation analysis mainly consists of two methods. The first method is for the engineer to give suggestions on the operation mode of the transformer according to the actual load of the transformer and combined with his own theoretical experience. , this method is usually not objective and rigorous enough, and there is a certain deviation from the actual result; the second method is to use the transformer to conduct a no-load loss test to obtain the no-load loss and short-circuit impedance of the transformer, but this method cannot be used in a short time Calculating the actual loss of the transformer will have a certain impact on the actual production and life
