An Integrated Management Systemof Condition Monitoring For GIS

Gas insulated Switchgear (GIS) is an important equipment in power system. It has more and more applications, and there is an increasing demand on the technical of GIS on-line condition monitoring.GIS consists of different equipments in a substation, therefore, GIS condition monitoring includes different items, and needs a heavy workload. For effective management of different equipments and their operations, a GIS online condition-monitoring integrated management system is developed to integrate GIS, computer network and condition monitoring. This system makes it convenient for the control center of power system to implement classification management and condition maintaining.The GIS online condition-monitoring integrated management system is operated in Window OS, and is developed with Visual C++, Winsock. The server receives the data form different clients, and classes the data through the two-level map system, implements data processing, saving and display. In this system, different functions are organized into some modules, including network module, graphics module, data processing module, security module and database module.Object Model and Object Oriented Technique are used in the system to improve the system's applicability and expansibility. On the basis of it, the system will be used to monitor other electric equipment. Long-dated object make it possible to link SCADA, MIS and equipment condition monitoring to share data each other.In this thesis, the system is a distributed one whose model is client/sever, including server, sampling client and data sharing client. The integrated management software is operated in server and data sharing client. The server and data-sharing client is a pc, and SQL Server is installed in server.In this thesis, the sampling client is a PC/104 embedded microcomputer that consists of the A/D model and the CPU/Ethnet model. The software for client runs under DOS operation system and is developed with C language. It includes mainprogram, interruption sub function and functions library. The client implements sampling of data, pre-processing, and data transfer of three kinds of variables.The online condition-monitoring integrated management system has passed through lab debugging and testing, and can run normally and smoothly. All destined aims of work have been achieved.
