Transformer dynamic capacity increasing system based on transformer monitoring

Abstract

A transformer dynamic capacity increasing system based on transformer monitoring comprises a temperature acquisition module, an infrared imaging module, an oil gas monitoring module, a control module, a wireless transmission module, a server and a monitoring terminal. The temperature acquisition module acquires a transformer winding hot spot temperature signal and transmits the signal to the control module, the infrared imaging module acquires a transformer surface infrared imaging temperature signal and transmits the signal to the control module, and the oil gas monitoring module acquires a transformer oil gas content signal and transmits the signal to the control module. The wireless transmission module sends the transformer winding hot spot temperature signal, the transformer surface infrared imaging temperature signal and the transformer oil gas content signal to the server. The server receives the transformer winding hot spot temperature signal, the transformer surface infrared imaging temperature signal and the transformer oil gas content signal sent by the wireless transmission module, discriminates and transmits data to the monitoring terminal, and the monitoring terminal displays state information of the transformer. The load of the transformer is dynamically increased.

Description

technical field [0001] The invention relates to the field of electric power information, in particular to a transformer dynamic capacity increasing system based on transformer monitoring. Background technique [0002] At present, some research has been carried out on the strategy of dynamic capacity increase of transformers. The main idea is based on the existing environmental conditions (sunshine intensity, ventilation, ambient temperature, sunshine time), current, transformer temperature (using sensors to collect transformer oil temperature) ) and other conditions, the maximum allowable current when the hot spot temperature of the transformer reaches the temperature limit is deduced through the corresponding mathematical model, so as to improve its power transmission and transformation capacity under the conditions of ensuring the normal operation of the transformer and reducing the life loss of the equipment. Most of the dynamic capacity increase strategies of transformer...

Problems solved by technology

Most of the dynamic capacity increase strategies of transformers are derived from mathematical models to obtain the hot spot temperature value, so as to improve the transmission capacity of the transformer on the premise of ensuring the safe operation of the transformer, which can only reflect the internal oil temperature of the transformer body, but such monitoring is one-dimensional It depends on the accuracy of the temperature signal collected by the temperature sensor. If the temperature sensor is damaged or the data is offset, it will cause a large error and cause hidden dangers.
