Abstract

The invention relates to an urban power distribution network evaluation system and method, for the purpose of solving the problem that evaluation result accuracy is affected by complex calculation process and errors of varying degrees between various scores because the scores of various indexes of the urban power distribution network are calculated and analyzed manually at present. The urban power distribution network evaluation system comprises a device for receiving external input data to be detected, a device for detecting the operating level of the urban power distribution network, a device for detecting the power supply capability of the urban power distribution network and a device for displaying a detection result. The urban power distribution network evaluation method comprises the steps of receiving the external input data to be detected, detecting the operating level of the urban power distribution network, detecting the power supply capability of the urban power distribution network and displaying the detection result. The urban power distribution network evaluation system and method belong to the power grid field.

Description

technical field [0001] The invention relates to the field of power grids. Background technique [0002] With the development of the national economy, the growth of power load has accelerated significantly, and there are higher requirements for the power supply capacity, power quality and power supply reliability of urban power grids. However, the original power grid equipment is obsolete and the technology is backward, which seriously affects the development of urban economy and people's work and life. In order to adapt to the development of the city, the transformation and expansion of the urban distribution network has been fully carried out, and the evaluation of the operation level and power supply capacity of the distribution network based on this premise has also been carried out. This work has great practical significance for correctly evaluating the current situation of the power grid, optimizing the structure of the distribution network, and improving the safety an...
