A method and system for heat dissipation temperature control of a transformer

Abstract

The invention discloses a heat dissipation and temperature control method and system of a transformer. The method comprises the steps that: a temperature acquisition module acquires temperature signals in a transformer and a transformer cabinet, and transmits the temperature signals to a data processing module for processing, and the like. According to the method, when the current signal is abnormal and the fault caused by the temperature factor is determined, the temperature is automatically adjusted, all temperature values at each moment are not needed to be considered during temperature control, only the needed temperature values are needed to be considered with emphasis, the vector dimension of the temperature sequence is processed along with the increase of time and the acquired temperature values, when the calculated amount of the temperature data and the time data is exponentially multiplied, the temperature adjusting instruction at the current moment is memorized, and the voltage is adjusted by accumulating on the basis of the temperature adjustment at the current moment at the next moment, so that the continuity of the voltage adjusting process of the transformer node in the temperature adjustment is ensured.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a method and system for controlling heat dissipation and temperature of a transformer. Background technique [0002] With the rapid development of my country's economy, the demand for electric energy in my country has been increasing in recent years, the capacity of transformers is also increasing, and the requirements for temperature control are also continuously improving. The higher the accuracy of temperature control, the higher the operating efficiency of the transformer. The higher it is, the more important it is to maintain the stable operation of the power system. [0003] Due to the continuous fluctuation of the power grid, the sensitivity of the transformer to temperature control is not high enough, resulting in the transformer not being able to respond to temperature changes in a timely manner, which will cause low operating efficiency of the transforme...

AI Technical Summary

Problems solved by technology

[0003] Due to the continuous fluctuation of the power grid, the sensitivity of the transformer to temperature control is not high enough, resulting in the transformer not being able to respond to temperature changes in a timely manner, which will cause low operating efficiency of the transformer, and will reduce the service life of the transformer, making it secondary Increased costs

In the current technology, the temperature control usually responds according to the data collected by the sensor, but this method needs to consider all the temperature values ​​at each moment. As the time and the collected temperature values ​​increase, the dimension of the temperature sequence vector also increases. The calculation amount of temperature data and time data increases exponentially, which will not only bring calculation delay, but also reduce the performance of transformer temperature control and voltage control, which will cause the start and stop of transformer node voltage regulation process during temperature regulation, and increase the transformer overload. and risk of overheating

The temperature change of the transformer has a process. If it cannot be adjusted correctly, the transformer will work outside the threshold temperature, which is not allowed.
