Fault case library, fault tree and fault spectrum construction method

Abstract

The invention relates to a fault case library, a fault tree and a fault spectrum construction method. Firstly, an efficient multi-level state detection data comprehensive index model is established, and test data are modeled from multiple dimensions. The intellectualization research of expert experiences, case libraries and rule bases is developed, and diagnosis techniques and multi-information fusion techniques based on various types of standardized state detection data are used for improving the accuracy of analysis and diagnosis. Secondly, construction techniques of standardized and intelligent typical fault case libraries are studied on the basis of fault case libraries and related relational libraries, and then the fault tree and the fault spectrum are constructed based on the fault case. Finally, a typical case library for on-site operation and maintenance of transformer equipment is constructed. The method can effectively ensure that power equipment operates under normal conditions, and can detect and eliminate the malfunction of the power equipment in time by detecting the data, the specialization and intelligence level of the on-site operation and maintenance is improved,the efficiency of transportation inspection and management and control capability for equipment status are improved, and status overhaul and assist decision-making are strengthened.

Description

technical field [0001] The invention relates to the technical field of substation equipment operation inspection, and more specifically, relates to a method for constructing a fault case library, a fault tree and a fault spectrum. technical background [0002] In the power industry, due to the large distribution area of ​​power grid equipment and the limited number of power experts, it is impossible for every substation to be dealt with by experts on site when a fault occurs. The form of video is fed back to power experts in real time and accurately, and power experts handle faults according to the equipment conditions in the video. This method has become an important guarantee for the safe operation of the power grid. [0003] With the development of wireless technology, the application of wireless transmission technology is more and more accepted by all walks of life. It is easy to install, flexible and cost-effective. Therefore, by studying wireless transmission technolo...
