Research On Monitor Module Of Grid Fault Diagnosis And Recovery System

The monitor module of fault diagnosis and recovery system could get and improve the grid module and real-time alarm information, identify faults happening and start diagnosis and recovery program. It makes fast network topology and recognizes fault zone. Multi threads achieve multiple functions of concurrency and self-test function makes tests to maintain safety. The monitor module supports and manages fault and recovery system.The global data of the fault diagnosis and recovery system is got by importing CIM and certain-moment data; Monitor module uses network SOCKET programming to read real time data from dispatching automation system; As the excess data still cannot provide enough useful information and the data is fuzzy and uncertain, it analyses, selects and makes the information perfect. It solves the information identification problems in emergency condition; It explains fast network topology analysis (using breadth-first method to search whole net and dynamic topology to track the net changes) to monitor real-time changes of the power grid running state. It finds out blackout area, the loss-power equipment set and suspected faulty equipment set, which effectively narrows the scope of diagnosis and improves diagnosis speed. Monitor module ensures blackout areas’switches and edge switches of every subsystems, which improves the efficiency of the recovery program searching for optimal recovery path. In order to improve the running efficiency and make full use of system resources, fault diagnosis and recovery system sets multiple functional threads, which are controlled by multi-thread management module; Self-detection module detects the running environment real-timely in case of unusual circumstances to make alarms for reminding dispatchers to take action. This paper bases on the Window platform, takes Visual C++as developing tools and ACCESS as database management system to achieve the development of the power grid fault diagnosis and recovery system monitor module. The test of Heilongjiang Hegang regional grid’s fault analysis process shows that the monitor module satisfies the design requirements.
