摘　　要：电网运行环境的复杂性增加了电网调度的难度。为了实时监测电网调度过程、保障电网安全运行,设计了一种电网调度运行可视化系统。利用能量管理系统(EMS)实时数据库和交互式反汇编器(IDA)实时数据库建立电网数据采集模块。通过ASExporer平台Windows操作系统和面向服务架构(SOA)体系建立联合熵维度评价模块。采用远动应用服务元素2(TASE.2)通信协议和地面控制数据联网系统软件建立电网调度运行模块。利用三维可视化平台开放图形库(OpenGL)和动画制作软件建立可视化展示模块,完成硬件系统设计。在此基础上,通过获取电压分布特征、计算先验知识丰富度、使用动画制作软件跟踪动态调度网络特征,确定电网调度路径,从而完成电网调度运行可视化展示,并及时调整电网调度运行薄弱环节。试验结果表明,该系统的潮流分布特征与实际潮流分布特征吻合,节点调度顺序与实际节点调度顺序相同。该系统能够准确展示电网潮流分布和节点调度顺序,帮助用户直观了解电网运行情况、提高调度员的在线审查能力,并减少局部无电调配和停电的风险。该系统具有较强的调度运行可视化效果和实际应用价值。The complexity of the grid operation environment increases the difficulty of grid scheduling.To monitor the grid scheduling process in real time and ensure the safe operation of the grid,a grid dispatch operation visualization system is designed.The real-time database of energy management system(EMS)and the real-time database of interactive disassembly(IDA)are utilized to establish the grid data collection module.The joint entropy dimension evaluation module is established through the ASExporer platform Windows operating system and service-oriented architecture(SOA)system.Grid dispatch operation module is established by using telecontrol application service element 2(TASE.2)communication protocol and ground control data networking system software.The three-dimensional visualization platform open graphics library(OpenGL)and animation production software are used to establish the visualization display module and complete the hardware system design.On this basis,by obtaining voltage distribution characteristics,calculating a priori knowledge richness,and tracking dynamic dispatch network characteristics using animation production software,the grid dispatch path is determined,so as to complete the visualization display of grid dispatch operation and adjust the weak links of grid dispatch operation in time.The test results show that the current distribution characteristics of the system coincide with the actual current distribution characteristics,and the node scheduling order is the same as the actual node scheduling order.The system can accurately display the grid current distribution and node dispatching sequence,help users intuitively understand the grid operation,improve the online review capability of dispatchers,and reduce the risk of localized no-power dispatching and power outage.The system has strong dispatch operation visualization effect and practical application value.
