| Over the years, due to economic backwardness and other reasons, Alxa power grid has the advantages of simple structure, small size, the dispatcher in grid monitoring depended more on the phone. Since2000, bureau of Alxa cable industry to speed up the power grid construction speed, and built the bureau made history as the first set of dispatching automation system."Eleven five" period, automation system structure and function has been further improved, access control and video system can also be applied to the lab for power grid dispatching operation, and provides important technical support and security role. But the attendant need dispatcher and automated attendant attention information also increased exponentially, relying solely on real-time system simple warning and attendant manual inspection and monitoring methods have been unable to meet the needs of digital power grid dispatching, existence of the labor intensity of operators on duty, power grid fault detection is not timely issues and pitfalls.In order to monitor important operation data of power systems and security operation support environment, in the first time discovery system running in the presence of abnormal situations, timely to remind the operator on duty for the corresponding treatment, reduce the burden of personnel, improve the level of safety of electrified wire netting, to establish a set of intelligent surveillance tool has be imperative.According to the actual situation of Alxa electric power dispatching automation, intelligent alarm system based on construction project, launched a series of design and research work. The first analysis of the Alxa region and the current situation of dispatching operation monitoring means to exist serious inadequacy, put forward to build intelligent alarm system on the urgency and significance. Then, from the practical point of view, expounds in detail the design objectives, technical requirements, key indicators and functional requirements, and the mapping of the overall scheme design. Next, the system hardware and software platform are analyzed, the hardware connectivity graph of the network and equipment configuration, the system software and the process structure presented, focusing on the system has the function to carry on the detailed design and application development. The paper also system key technology research, compiled test outline and enumerates the actual case, the system function and validated the practicability. Finally, summarizes the watch alarm system construction achievement, pointed out the next research directionIntelligent automatic watch alarm system put into use, make Alxa dispatching operation monitoring management level than in the past has been significantly improved, to achieve the "environment, system, network, data" four level monitoring and alarm in real time, improves the fault information analysis level, effectively eliminating the power grid security. |
