Description
Technical field
The present invention relates to a kind of method obtaining grid equipment fault message based on multi-source redundancy statistics, belong to technical field of electric power automation.
Background technology
Within the scope of tracking, grid equipment fault message is the important reference foundation that the grid equipment owner grasps power generation operation and power supply reliability situation in compass of competency.Obtaining the whole network tracking device fault information is rapidly and accurately understand the important support means of grid equipment running status, degree of depth grasp equipment O&M level, General Promotion power supply reliability in time.
At present, there are three reasons causes For Provincial Power Grid Corporation to be difficult to reach by automation and information-based means the object obtaining all devices fault message in compass of competency quickly and accurately: one, causality is there is between the relevant multi-source information that same equipment breakdown separating brake event is corresponding, master slave relation, the multi-dimensional complicated logical communication links such as ordinal relation, simultaneously due to plant stand capital construction and reorganization and expansion, overhaul of the equipments and test, the reasons such as plant failure or exception, add the popularization of scheduling controlling integration and Unattended substation, cause equipment have an accident separating brake time transformer station on send a large amount of even magnanimity information (information content of intelligent substation panoramic view data is much larger than conventional substation) to scheduling station EMS EMS, from magnanimity information, excavate authentic and valid fault message is technological difficulties, its two, dispatching management information system OMS, production management system PMIS cause it cannot avoid information time lag and careless mistake because the many dependences of its maintenance of information manually complete, its three, present again the feature of high granular, spatial and temporal distributions between the multi-source information of three digest journals, between part multi-source information, even there is the factors such as inconsistency, paradox, weak dependence.Therefore still adopt the statistical of artificial screening traditionally, from bottom to top, summarizing and reporting step by step, inefficiency and accuracy are difficult to ensure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method obtaining grid equipment fault message based on multi-source redundancy statistics, in comprehensive EMS, OMS, PMIS three digest journals, information sifting is carried out and correct statistics grid equipment fault in many redundancies source, more accurately, reliably, rapidly can count grid equipment fault message on request.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Obtain a method for grid equipment fault message based on multi-source redundancy statistics, comprise the steps:
