Research And Application Of The Condintion-based Maintenance For Power Equipment

Implementation of the power grid equipment state overhaul is to improve the equipment and power grid operation safety, reliability and economy. Along with the trend of the development of power grid construction in China and rising state overhaul technology, electrical equipment state overhaul mode with its highly targeted, economic and reliable advantages of get more and more application in the electric power system. In this case, the power supply company in urgent need to develop a can satisfy the power supply company daily system of theoretical line loss calculation, especially in recent years our country electric power supply company scale unceasingly expands, the number of power users is in constant increase, the complexity of the whole grid are also gradually increased. In the development of the power grid and the monitoring system of distribution network automation also got very good development, so for the whole grid of relevant data and information collection work also become easier. Based on these aspects of content, using the current more mature theoretical line loss calculation algorithms and comply with the current distribution network automation monitoring system, data were collected by to line loss assessment of the power supply company provides more authoritative data.This topic is designed CQDMIS system contains a number of sub-systems, and maintenance scheduling system overhaul bill is one of two major subsystems are used workflow technology, in order to facilitate user operation, maintenance and repair of ticket program main interface design, maintenance query module interface design and database, report design, using nearly WINDOWS operating style; the system to Windows 7 operating system as a network operating platform, using the latest GPRS network communication technology, using SQL Server 2008 database management system, Windows Server 2008 as server, client/server architecture, the absolute guarantee data consistency and enables system resources to achieve information sharing within the WAN range. This web-based non-transparent communication reliable connection, can absolutely ensure the reliability and integrity of data transmission, event information simple distributed SCADA systems often encountered loss and remote operation success rate and so the situation in the state power grid equipment overhaul the system can be completely avoided. It completed the development of specific technical power company grid equipment state model for a detailed analysis of the needs of the system carried out a detailed analysis, and system architecture selected for the analysis. According to the actual needs of power dispatch, process management as the guiding ideology, implement process definition to overhaul bill, overhaul plan for network equipment maintenance system detailed design, implementation, provide implementation privileges entirely by the client for the scheduled user control The online version of distributed computer systems. Network equipment maintenance system for testing, the results of tests carried out finishing, induction and analysis, in-depth study based on the grid condition assessment of risk prevention management system, for the post of statistical methods determined the equipment failure rate no longer applies to the device status maintenance decision optimization problem, we propose a new method of calculating the failure rate.Thesis design and implementation of condition-based maintenance intelligent system can power different devices test data analysis and processing, health status, and obtain power equipment maintenance policy, it has some practical value in the field of power equipment fault detection and prediction.
