【摘要】 为直观描述特高压(UHV)输电线路电磁散射空间分布及其对周边敏感设施的影响,针对特高压输电线路电磁散射高效模型对无线电台(站)干扰仿真和防护设计平台建设的需要,采用组件地理信息系统(GIS)开发技术,以VS 2010(C#语言)为平台、Arc Engine(AE)10.0组件为工具,实现了特高压交流试验示范工程输电线路电磁干扰(EMI)云图的3维可视化。采用特定数据接口进行电磁干扰计算,并将计算结果以电磁干扰云图(等位线图)的方式展示在输电线路3维场景中。研究结果表明:3维可视化技术可以将输电线路电磁干扰结果以更形象、直观的方式呈现给用户,并可以进行输电线路与周边敏感点的空间距离量测和干扰场强大小查询,是电力系统和3维GIS新的结合点。更多还原

【Abstract】 To graphically describe the spatial distribution and influence of electromagnetic scattering of ultra-high voltage(UHV) transmission lines on surrounding sensitive facilities,focusing on the demands of interference simulation and protection design platform for efficient model of UHV transmission lines electromagnetic scattering, we achieved the 3D visualization of electromagnetic interference(EMI) cloud image for UHV alternating current demonstration project based on the component geographic information system(GIS) technology, VS 2010(C# language) platform, and Arc Engine(AE)10.0 tool. The EMI calculations were made via particular data interface, and then the results were presented in the 3D visualization scene of transmission lines in the form of EMI cloud images(equipotential contours). The research results show that, the 3D visualization technologies can more graphically and straightforwardly present the EMI results to the users, and can implement the spatial distance measurement and EMI intensity query between transmission lines and surrounding sensitive points, which are the new combinations of power system and 3D GIS.更多还原
