摘要
随着电网规模的扩大,复杂电网分析可视化技术的需求也越发紧迫。本文以PowerBuilder和MapInfo平台为集成开发环境,把复杂电网分析过程与基于地理信息的可视化技术相结合,设计了电网分析模块的功能、系统架构和数据结构,探讨了潮流计算分析可视化技术的关键技术和实现方法,实现了电网故障对城市供电的影响分析,动态直观地描绘了不同电网运行方式下的供电状态。以IEEE 14节点电网为例,验证了潮流计算可视化分析模块的可行性和实用性。
With the enlarging of power grid,the demand on visualization technology of complex power grid analysis has become increasingly urgent.In this paper,under integrated development environment on MapInfo and PowerBuilder platform,the function,system architecture and data structure of electric network analysis module are designed by combining analysis process of complex power grid and visualization technology based on geographic information.In addition,key visualization technology of load flow calculation and its realization method are discussed,based on which the influence of grid fault on power supply of urban power network is analyzed and power supply statuses of urban power network are described dynamically and intuitively under different grid operation modes.Finally,taking IEEE-14 nodes network as example,the feasibility and validity of visualization analysis module of load flow calculation are verified.
