Description
technical field [0001] The invention relates to the technical field of power resource management, in particular to a method and a device for optimal allocation of distribution transformer resources. Background technique [0002] The heavy overload of the distribution transformer will not only increase its own loss, but also bring great hidden dangers to the safe operation of the power grid. Power supply companies sometimes use distribution transformer replacement to solve or alleviate the problem of heavy overload of distribution transformers in a given area. This method only optimizes the allocation of distribution transformer resources in a given area without additional Increased equipment investment, higher economy. However, it is difficult to achieve the desired effect by changing the position of the distribution transformer based on the experience of the staff. Therefore, it is necessary to invent a distribution transformer resource optimization allocation method to s...
