Research On Condition Evaluation And Risk Assessment Based Condition-based Maintenance Of Substation Equipment

Based on substation equipment safety and economy of the state evaluation model based on risk assessment and risk model to calculate the value of equipment, provide the basis for state maintenance, providing decision support for the grid operation. For security risks due to factors craft substation equipment, technology, and other losses incurred and extended to develop condition-based maintenance programs; One of the state evaluation model, the risk assessment model based on security, reliability, environment, and other factors to avoid the hidden costs, improve reliability and economy of operation and maintenance.Evaluation data on the impact of the state as well as the reliability of the device status quantitative analysis, according to a predetermined quantitative criteria for various types of data to analyze and solve current and future equipment health index, the probability of failure. The state can provide the basis for evaluation of equipment replacement, repair, renovation and planning decisions, and its main role is to manage reliability, reasonable arrangements for equipment maintenance and investment planning ancillary assets.Risk assessment model analysis and processing of the equipment failure probability and consequences of failure to calculate the value of a variety of risks in terms of power, equipment, people and the environment. Risk assessment is not limited to the management of reliability, maintenance resources, but also to rise to the height of the grid management decision-making basis for the asset management and investment planning.The example shows that the method can be quantified state maintenance equipment health index, failure probability and risk values to guide the replacement, renovation, operation and maintenance tests, etc., With engineering application.
