Method for evaluating running condition of distribution network regulation and control integrated system

Abstract

The invention discloses a method for evaluating the running condition of a distribution network regulation and control integrated system, which includes the four steps as follows: (1) determining theevaluation index selecting principle of the distribution network regulation and control integrated system; (2) determining the evaluation index grading principle of the distribution network regulationand control integrated system; (3) based on an analytic hierarchy process and a fuzzy comprehensive evaluation approach, calculating the value of each sub index, getting a comprehensive score, and evaluating the running condition of the system according to the score; and (4) displaying the evaluation result through a radar chart analysis approach. Dynamic monitoring, evaluation and comprehensivedisplay of the important indexes of the running state and application situation of a master station system are realized. Effective guidance is provided for users to improve the level of automation application and the level of operation and maintenance of regional distribution networks.

Description

technical field [0001] The invention relates to a method for evaluating the operation status of a distribution network regulation and control integrated system, which belongs to the technical field of distribution networks. Background technique [0002] The distribution network is the key infrastructure of the city and an important link connecting the power grid and users. It has the basic characteristics of many points, long lines, wide area, complex structure, and cross-cutting management links. For a long time, the technical support means of distribution network regulation and management has been relatively weak. With the continuous deepening of the construction of the large-scale operation system of the State Grid Corporation of China, the distribution network regulation work urgently needs to be developed in depth to effectively improve the level of distribution network regulation and management. With the comprehensive promotion and construction of smart grid, distribut...

Problems solved by technology

[0004] The operation status of the distribution automation master station is affected by many factors such as the operating environment, hardware resources, network resources, system application level, daily operation and maintenance work, etc. However, there is currently a lack of operation supervision and assessment index system and effective analysis and evaluation for the distribution automation master station The methods and evaluation indicators cannot fully and objectively reflect the system operation and application level, and the application of system functions needs to be further strengthened

At present, the establishment of analysis and evaluation indicators is limited, limited to a small number of indicators such as remote signaling success rate, remote control success rate, and remote control usage rate. There is a lack of system stable and reliable operation control indicators such as system load rate, and state control indicators such as SOE matching degree and defect elimination efficiency. Overall analysis and evaluation
