The Design And Implementation Of Fault Monitor System For Power Schedule Based On LabVIEW

The faults happen in the power system have growing influences to the system with the sweeping and complexity of the power system and closed relationship between different areas. Meanwhile, with the development of country economy, residents require better electrical quality. Because of the inevitability of the faults in the power system, to find the position of the fault after it happened in the system, make sure the fault's character and whether the related protect activities is right, and then recovery the system in time after the accident happen, we need applied and proficient fault diagnosis system to apply assistant evidence to the yardman.The reliability and speed of the power system's fault diagnosis have direct influence to the power net's automate level. According to the fault structure characteristic of fault monitor system for power schedule of east China power net, the paper design and realize the fault diagnosis module by the Fault Tree Analysis. And make the major effort in designing the customer configuration module and put in maintenance interface with relatively self-contained with base abilities.The host computer monitor module is realized by LabVIEW. It has flexible format, blocking code, clear structure. It adopts object-oriented method and concept, which benefit the development and reuse of the software.The paper makes the main research in the following aspects:Based on the traditional fault tree structure, the paper unify the normal logical operation and the special logical operation with the weight sum operation, then gives a new and complete fault tree analysis method.Raise a relatively complete RT monitor system project, which include database design, maintenance interface and .etc.Bring out the main function's realization of customer configuration module based on configuration files.Meanwhile, the paper comes down to plenty of normal function's realization of LabVIEW. It involves the use of all the basic format data: numeric, Boolean, string and so on. It involves most maths operation: basic maths operation, format transform,...
