Electrical equipment state maintenance system

Abstract

The invention provides an electrical equipment state maintenance system. The electrical equipment state maintenance system comprises an operation and maintenance base layer platform, a state monitoring module, a state evaluation module, a risk assessment module, a fault diagnosis module and a maintenance strategy module, wherein production area I data of a power grid system and production area III data of the power grid system are integrated on the operation and maintenance base layer platform, the state monitoring module is used for collecting on-line monitoring data of electrical equipment and operating environment information of the electrical equipment through the operation and maintenance base layer platform, the state evaluation module is used for evaluating the on-line monitoring data according to state evaluation standards of the electrical equipment to acquire an electrical equipment health state represented by the on-line monitoring data, the risk assessment module is used for calculating the risk index of the electrical equipment according to risk assessment standards of the electrical equipment, the fault diagnosis module is used for diagnosing faults of the electrical equipment and generating a fault diagnosis report according to the health state and the risk index of the electrical equipment, and the maintenance strategy module is used for generating maintenance strategy information of the electrical equipment according to the health state, the risk index and the fault diagnosis report of the electrical equipment. By means of the electrical equipment state maintenance system, evaluation, assessment and predication are automatically carried out on the power grid system, and therefore the automation level and the intelligentization level of the power grid system are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a state maintenance system for electric equipment. Background technique [0002] In the long-term operation of the power grid system, it is inevitable that the performance will gradually decline, the reliability will decrease, and the failure rate will increase, which will endanger the safe operation of the system. Therefore, the operating status of the power grid system must be monitored. [0003] The traditional state monitoring method of power equipment is frequent manual inspection and regular preventive maintenance and testing. This system of frequent inspection and regular maintenance plays a certain role in guaranteeing the safe operation of power equipment. , the requirements for the reliability of power generation, transmission, power supply and power consumption are getting higher and higher. At the same time, the reform of the power grid system is be...

Problems solved by technology

[0005] However, due to the limitations of management, technology and many other factors in the data source of existing condition monitoring, it is impossible to obtain first-hand information in terms of data fusion, and it is often difficult to interact with production area I data such as dispatching and relay protection. It is the quasi-real-time data that is mapped to the interface through the automation system. In terms of condition monitoring and construction, the data of the production zone III is often the main one. The equipment with problems is evaluated according to the man
