The invention discloses a state evaluation method and a state evaluation device for key equipment of a photovoltaic system. The method comprises the steps of establishing a state evaluation basic model for the key equipment of the photovoltaic system; according to the state evaluation basic model, selecting an indirect measuring amount for the key equipment of the photovoltaic system, and calculating the value of the indirect measuring amount; setting a state evaluation scoring standard for the key equipment of the photovoltaic system, and scoring the indirect measuring amount according to the state evaluation scoring standard and the value of the indirect measuring amount, and scoring a direct measuring amount according to the state evaluation scoring standard; calculating the weight of each component in the key equipment of the photovoltaic system by means of an analytic hierarchy process, and generating a state evaluation result for the key equipment of the photovoltaic system according to the scores of the indirect measuring amount and the direct measuring amount of the key equipment of the photovoltaic system. The state evaluation method and the state evaluation device can supply scientific basis for next-step risk evaluation and maintenance decision.
Description
technical field [0001] The invention relates to the technical field of electric power systems, in particular to state evaluation of key equipment of a micro-grid, in particular to a state evaluation method and device for key equipment of a photovoltaic system. Background technique [0002] The process of status assessment of key equipment of photovoltaic system is to record, classify and evaluate its own operating status and other information, so as to provide decision-making for risk assessment and condition maintenance of equipment. Although the status assessment of electrical equipment has received great attention in recent years, the status assessment of key equipment in photovoltaic systems has not met the practical requirements, and there are few related theoretical studies. There are many problems in assessment technology, especially the lack of practical state assessment theory and methods to guide the state assessment of key equipment in photovoltaic systems. Cont...
