Abstract

The invention provides a distribution transformer capacity control method and system. Power using users in a power grid are classified, annular maximum practical coefficients of various users within a collection year limit are respectively sampled and computed, a maximum practical coefficient tendency chart changing with the operation time of distribution transformers is drawn according to the data, the maximum practical coefficients of different distribution transformers within the year limit are looked up, and finally the capacity of each distribution transformer is controlled according to the maximum practical coefficients. In the whole process, man-made subjective participation is avoided, strict data acquisition and computation are adopted, and the result accuracy is ensured, namely accurate capacity control of the distribution transformers can be achieved. In addition, a maximum practical coefficient selecting principle is adopted to ensure that the load demand can be meet and high device utilization rate can be also obtained, and accordingly reasonable utilization of the power grid resources and safe running of the power grid are ensured.

Description

technical field

[0001] The invention relates to the technical field of power grids, in particular to a distribution transformer capacity control method and system. Background technique

[0002] With the continuous increase of user demand for electricity, the phenomenon of large-scale industrial expansion and installation of electricity is becoming more and more common. In the process of industrial expansion, the most important thing is how to reasonably select the capacity of distribution transformers according to the actual needs of power users. If the capacity is too large, it will increase the investment in equipment purchase, installation, operation and maintenance, resulting in waste; otherwise, it will cause overload operation of distribution transformers, making it difficult to meet power demand and reliability. Therefore, practical coefficients are often used to guide the selection of transformer capacity and improve the utilization rate of equipment during industri...
