Method for evaluating whether urban power supply network reaches world first-class level or not

Abstract

The invention provides a method for evaluating whether an urban power supply network reaches the world first-class level or not. The method comprises the following steps: carrying out development survey and feature analysis on world first-class urban power supply networks; analyzing the content of constructing a target power supply network into the first-class power supply network; building index systems; setting evaluating standards; analyzing the difference between the target power supply network and the world first-class power supply network, and providing improvement measures. The method provides core indexes capable of representing the characteristics of the world first-class power supply networks, analyzes the professional driving factors of the core indexes and decomposes layer upon layer to form secondary indexes that professional departments are in charge of. The method not only conforms to the characteristics of the world first-class power supply networks and the development trend of the international power supply networks from the macroscopic aspect, but also from a microscopic aspect, facilitates the classified management of the professional departments. The method can comprehensively and objectively reflect the development level and the defects of the target power supply network, weigh differences between the urban power supply network and the world first-class level and lead the development emphasis and direction of the power supply networks.

Description

technical field [0001] The invention belongs to the technical field of urban power supply network evaluation, in particular to a method for evaluating whether the urban power supply network has a world-class level. Background technique [0002] The traditional power grid evaluation usually starts from a single characteristic of the power grid, such as power supply reliability, economy, security, power supply quality, etc., and conducts technical and economic evaluation of the power grid. The comprehensive evaluation of multiple indicators mainly focuses on the power supply quality, operation level, etc. from the perspective of the interests of power users, as well as the economics of the operation of power supply companies. On the one hand, the pursuit of maximizing the benefits of power supply enterprises. [0003] In recent years, with the continuous expansion of the scale and complexity of the urban power supply network, the characteristics of the power supply network ha...
