抛物线边界随机幅值的局部放电图谱虚拟仿真培训系统OA

In order to solve the problems of high cost and high risk of substation gas insulated switchgear(GIS)and high-voltage switch cabinet partial discharge live detection skill training device,the substation virtual working environment was constructed with virtual reality(VR)technology.Meanwhile,the three-dimensional model of 220 kV GIS and 10 kV switchgear equipment was established by using 3ds MAX software polygon modeling method.The phase resolved partial discharge(PRPD)and phase resolved pluse sequence(PRPS)graph data of typical partial discharge defects was obtained based on the data analysis method of real recording data(DAT)files.A random amplitude presentation method of polynomial function parabolic boundary was proposed based on the characteristics of typical partial discharge PRPD map,and the three-dimensional dynamic presentation of typical partial discharge fault map was realized by Unity3D engine.Students can practice substation live detection skills such as interval patrol inspection,PD detection instrument operation,fault map judgment and fault location from the first perspective of three-dimensional simulation.
