Design And Implementation Of Condition Monitoring System For Power Transmission Equipments

Electricity transmission lines are an important part of the power system. With the rapid development of the electricity construction, expanding the size of the grid, the work of grid construction and maintenance has become more and more frequent. The power transmission link as transmission ligament with the features of long distance, dispersion, and difficulty to inspections and maintenance, need regular inspection and maintenance, which needs many workers, high intensity work, is largely affected by environmental and human factors with the heavy maintenance task. To improve the management of transmission lines, enhance the reliability of power system operation, establishing a reliable, multi-functional power transmission equipment condition monitoring system is urgent, which is the development direction of maintenance and reliable operation of transmission line.In this dissertation, the power transmission equipment condition monitoring system using java technology, the newer and reliable JDK5.0/6.0as a programming environment, and the best practical SOA, can ensure the compatibility and openness of the system largest. The system has analysis platform and data centers and establishes state maintenance database with the idea of the data center and can provide high-quality data for the condition assessment and maintenance for decision support, while with the use of appropriate techniques it can achieve the legitimate online data analysis and presentation to achieve efficient device state management. With the above foundations the system use expert evaluation system in order to achieve a more automated and intelligent evaluation of condition maintenance, fault diagnosis and condition analysis forecasting work. The functions of the system are as follows:Electricity transmission line condition monitoring, meteorological environmental monitoring, wire monitoring, line tower monitoring, line tower accessories monitoring management.System has been applied in the pilot by Xinjiang Electric Power Company. The system improves the extent of integration in online monitoring about Xinjiang power transmission line. According to the integration state monitoring strategy, only where necessary and in accordance with the best number of times going on equipment maintenance, and reduce or delay regular maintenance and replacement of equipment and components, thus which can reduce outage time and save the maintenance costs. Condition monitoring and evaluation system can improve the ability to prevent catastrophic faults of electricity, thereby gain strategic benefits, including enhancing the overall security of the system, avoiding loss and damage in catastrophic faults for the operator and the public, to avoid potentially significant impact according to system instability, loss load and environment pollution.
