基于数字化映射的开关柜状态监测技术研究
Research on Switchgear Condition Monitoring Technology Based on Digital Mapping
摘要
Abstract
With the progress of power system,the requirements for grid reliability are increasing.As a key power equipment,the discharge and overheating states of switchgear in operation often trigger multiple types of faults,thus seriously affecting the reliability of power supply.Existing switchgear detection methods mainly focus on the analysis of two-dimensional diagrams,which is difficult to comprehensively reflect the multi-physics field state in three-dimensional space.Therefore,in this study,a multi-physics field coupled finite element model is adopted to explore the temperature and electric field distribution of the switchgear under the operating state.Besides,on the basis of the simulation results combined with the on-site operating state,an agent model of the switchgear based on radial basis function(RBF)neural network is constructed,which can significantly shorten the simulation time.In addition,a switchgear fault diagnosis algorithm based on adaptive neuro-fuzzy inference system(ANFIS)is also studied,and the visual presentation of switchgear state information is realised with the help of Unity,which improves the accuracy and real-time performance of switchgear data monitoring and provides a new way of thinking for preventive operation and maintenance of switchgear.关键词
