Abstract

The invention is applicable to the technical field of power grid asset evaluation, and provides a power grid asset safety performance evaluation method and device in a full life cycle. The method comprises the following steps: establishing an initial cost index within the whole life cycle of power grid assets, the initial cost index being a cost index which does not comprise a safety factor coefficient and an efficiency factor coefficient; establishing an efficiency index according to the power supply reliability coefficient and the voltage qualification rate coefficient, and establishing a safety index according to the accident safety coefficient; and according to the initial cost index, the efficiency index and the safety index, establishing a safety efficiency evaluation model of the power grid asset in the whole life cycle. According to the method, safety and efficiency factors are comprehensively considered for evaluating the economic efficiency of the power grid assets, and the evaluation precision of the power grid assets in the whole life cycle is improved while the effectiveness of safety efficiency evaluation is ensured.

Description

technical field [0001] The invention belongs to the technical field of power grid asset evaluation, and in particular relates to a method and device for evaluating safety performance in the whole life cycle of power grid assets. Background technique [0002] Asset life cycle management (Life Cycle Asset Management, LCAM) is to reduce the total cost of assets in the whole life cycle by optimizing the whole process of asset formation. Minimization of life cycle costs and management methods for reliable and safe use of assets (or equipment). The process of asset life-cycle management integrates the process of value flow, physical flow and information flow, and arranges and manages planning, procurement and construction, operation and maintenance, and post-retirement according to time series, with the purpose of realizing lean management of assets. [0003] The State Grid Corporation takes power grid assets as the research object, uses asset life cycle management to conduct ass...
