Embodiment Construction

[0070] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0071] The comprehensive evaluation theory is a process in which the evaluator analyzes all aspects of the evaluation object, conducts quantitative and non-quantitative measurements on the functions of the evaluation object according to the evaluation standards, and finally synthesizes all aspects of information to obtain a reliable and logical evaluation conclusion. . Comprehensive evaluation theory can be divided into qualitative and quantitative according to the subjective and objective evaluation methods:

[0072] (1) Qualitative evaluation method

[0073] The meaning of the qualitative evaluation method is not to use mathematical methods, but to directly make qualitative conclusions about the value of the evaluation object based on the evaluator's observation and analysis of the evaluation object's usual performance, reality, or literature. Com...

Abstract

The invention relates to a power grid performance comprehensive evaluation method and system. The method is characterized by comprising the steps that (1) factors influencing power grid performance are recognized and analyzed from different aspects, and power grid influence factors are determined; (2) according to the evaluation index system construction principle, a power grid performance evaluation index system is established; and (3) an entropy method is adopted to perform weighting on all evaluation indexes in the power grid performance evaluation index system, a matter-element extension comprehensive evaluation model based on the entropy method is established, and the power grid performance is comprehensively evaluated. The power grid performance comprehensive evaluation method and system are high in standardability, have the advantages of being easy and convenient to use, quantitative and rigorous and therefore can be widely applied to the field of power grid performance evaluation.

Description

technical field [0001] The invention belongs to the field of power grid performance evaluation, and in particular relates to a method and system for comprehensive evaluation of power grid performance. Background technique [0002] In recent years, my country's social economy has been continuously developed, power technology has been continuously updated, and the requirements for power supply quality and reliability have also been continuously improved. All of these have put forward higher requirements for the overall performance of the power grid. With the gradual optimization of the business process of the company's development, the level of lean management has been significantly improved, and the needs of various professions for detailed data and real-time information are becoming more and more urgent. Moreover, the comprehensive establishment of a modern company with "one strong and three excellent" is essential for the construction of a strong smart grid and efficient ent...
