随着电力系统的进步,对电网可靠性的要求不断增加。作为关键电力设备,开关柜在运行中的放电和过热状态常引发多种类型的故障,从而严重影响供电的可靠性。现有的开关柜检测方法主要侧重于二维图表的分析,难以在三维空间中全面反映多物理场状态。针对此问题,采用多物理场耦合有限元模型,探究了开关柜运行状态下的温度和电场分布,并基于仿真结果结合现场运行状态,构建了基于径向基函数(radial basis function
RBF)神经网络的开关柜代理模型,可大幅缩短仿真时间。此外,还研究了基于自适应神经模糊推理系统(adaptive neuro-fuzzy inference 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.
