Transformer area heavy overload transformer capacity increasing capacity optimization method

Abstract

The invention provides a transformer area heavy overload transformer capacity increasing capacity optimization method, which comprises the following steps of: firstly, determining a to-be-selected maximum load data set of a to-be-selected transformer in a rated service life, and then determining a cost function of the to-be-selected transformer in the rated service life according to capacity increasing parameters and the rated service life of the to-be-selected transformer; then acquiring the maximum load demand of the transformer area, and determining the constraint condition of the to-be-selected transformer according to the capacity increasing parameter of the to-be-selected transformer, the maximum load demand of the transformer area and the to-be-selected maximum load data set; and finally, determining the capacity-increasing capacity of the target transformer according to the cost function of the to-be-selected transformer in the rated service life and the constraint condition. By comprehensively considering conditions such as capacity increasing parameters of the to-be-selected transformer and the maximum load demand of the transformer area, the cost function and the constraint condition of the to-be-selected transformer in the rated service life period are established, so that the capacity increasing capacity of the heavy overload transformer in the transformer area can be optimally configured, and the method has relatively high practicability.

Description

technical field [0001] The invention belongs to the technical field of planned operation of the power distribution side of a power system. More precisely, the invention relates to a method for optimizing the capacity of a heavy overload transformer in a station area. Background technique [0002] With the continuous development of my country's national economy and the continuous improvement of people's living standards, the scale of electricity consumption in the whole society continues to grow, and a large number of installed distribution transformers are in a state of overload or heavy overload for a long time. Most of these heavy overloaded transformers have experienced abnormal aging or internal potential failures, which have great hidden dangers. There are several transformer explosions in Taiwan and Taiwan every year all over the country. The replacement of such transformers has become the focus of power companies. [0003] As an important electrical component widely u...
