Problems solved by technology

[0004] The purpose of the present invention is to, on the one hand, solve the problem that the identification sensitivity of partial index data degradation is too low due to the difference in importance in the weighting process; The overall operating status of the primary and secondary equipment of the on-column switch provides reference and guidance for arranging inspections of the on-column switchgear

Embodiment Construction

[0030] The specific implementation of the present invention will be further described below with reference to the drawings and examples.

[0031] figure 1 It reflects the specific process of the evaluation method and system of the complete set of equipment on the pole switch. A state assessment-based primary and secondary fusion column switch inspection strategy includes:

[0032] (1) Collect relevant operating experience and expert opinions, and use the analytic hierarchy process to determine the constant weight of the index importance. Since the constant weight of the index importance is fixed, the process only needs to be performed once, and then the obtained weight can be directly used The specific process is as follows:

[0033] According to the fault type reflected by the on-column switch body and the secondary part of the operating state and the non-operating state of the three-part indicators, the impact on the equipment operating reliability and operating experience, combi...

Abstract

The invention relates to a primary and secondary fusion pole-mounted switch inspection strategy based on state evaluation. The primary and secondary fusion pole-mounted switch inspection strategy comprises the following processes in a period of completing primary inspection / maintenance: determining an index importance constant weight; emptying the state quantity data set D1 at the beginning of each inspection period; sampling on-line monitoring data of a primary and secondary fusion pole-mounted switch state index and adding a sampling value into D1; calculating a variable value weight for describing the degradation degree of each state index data based on D1; synthesizing the variable value weight and the constant value weight by adopting a combined weighting method to jointly determine aweight matrix; and the current state of the pole-mounted switch is evaluated by combining a fuzzy comprehensive evaluation method, and a corresponding inspection strategy is adopted accordingly. According to the state evaluation-based primary and secondary fusion pole-mounted switch inspection strategy provided by the invention, the operation states of the primary part and the secondary part of the pole-mounted switch can be reflected more comprehensively. In addition, the adopted combined weighting method can avoid the problem that the identification sensitivity of partial index degradationis too low due to importance difference of a common weighting method.

Description

Technical field [0001] The invention relates to the evaluation of the state of power distribution switch equipment of a power system and its inspection strategy, in particular to a state evaluation-based primary and secondary fusion on-post switch inspection strategy. Background technique [0002] With the development of smart grids, the degree of cyber-physical integration of power equipment is increasing, and secondary equipment will be more integrated into primary equipment, gradually becoming integrated and integrated (Yuan Hao, Qu Gang, Zhuang Weijin, etc. Grid Discussion on the content of secondary equipment condition monitoring[J].Automation of Electric Power Systems,2014,38(12):100-106.2.Analysis of the integration of ECT and EVT in the primary and secondary integration of intelligent power distribution equipment[J].Power Capacitors and Reactive power compensation, 2019,40(01):108-114), has caused the coupling between primary and secondary devices to become stronger and s...
