【摘要】：对500kV超高压主网架输电线路采用等电位带电作业方式提高设备状况,已经成为输电线路状态检修的重要检修策略,也是电网发展和供电可靠性的必然需求。而多回路超高压输电线路的塔头紧凑布置型式又对带电作业的电气安全距离的控制带来困难,因此需要为500kV同塔多回输电线路的带电作业方案的模拟、校核提供一个可视的、快速模拟的平台,为带电作业最关键的进电场过程提供符合现场实际情况的三维可视化的模拟。三维可视化技术的发展,结合科学计算可视化和虚拟现实技术,同时利用输电线路信息和地理信息,为输电线路的三维可视化提供了技术支撑。论文探讨了利用多源激光雷达测量技术对输电线路进行三维数据采集,精细三维建模;实现塔头工频电场分布计算模拟和带电作业仿真模拟及安全距离的实时量测展示;探讨了三维可视化系统环境搭建、实现三维模型数据无缝集成、三维浏览查询等三个主要问题。论文按照面向对象的软件开发要求调查分析了系统的具体需求与系统设计方案,在需求分析阶段,通过用例图、业务流程等方法详细阐述了系统需实现的主要功能;在系统设计阶段,提出了多层体系的系统总体架构和B/S技术结构,描述了数据处理、三维模拟、浏览查询等主要系统模块的设计,介绍了系统数据库的设置情况;在系统实现阶段,简述了系统开发环境和软硬件环境配置,描述了系统功能的实现过程,和部分界面截图及实现代码。最终实现了500kV同塔多回输电线路带电作业的进电场过程的三维可视化模拟。
[Abstract]:It has become an important maintenance strategy for 500kV UHV main transmission lines to improve the equipment condition by using equipotential live working mode, and it is also an inevitable requirement for the development of power network and the reliability of power supply. However, the compact arrangement of tower heads of multi-circuit UHV transmission lines makes it difficult to control the electrical safety distance of live operation. Therefore, it is necessary to provide a visual method for the simulation and verification of live operation schemes of 500kV multi-circuit transmission lines with the same tower. The platform of rapid simulation provides 3D visual simulation in accordance with the actual situation of the field for the most critical electric field process in live operation. With the development of 3D visualization technology, combined with scientific computation visualization and virtual reality technology, transmission line information and geographic information are used to provide technical support for 3D visualization of transmission lines. This paper discusses the use of multi-source lidar measurement technology for transmission line 3D data acquisition, fine three-dimensional modeling, tower head power frequency electric field distribution simulation, live operation simulation and real-time measurement of safe distance display. In this paper, three main problems are discussed, such as the construction of 3D visualization system environment, the seamless integration of 3D model data and the 3D browsing query. According to the requirements of object-oriented software development, the paper investigates and analyzes the specific requirements of the system and the system design scheme. In the stage of requirement analysis, the main functions of the system are described in detail by means of use case diagram and business process. In the stage of system design, the system architecture and B / S technology structure of multi-layer system are put forward, the design of main system modules such as data processing, 3D simulation, browse and query are described, and the setting of system database is introduced. In the phase of system realization, the configuration of system development environment and software and hardware environment is briefly described, and the realization process of system function, some interface screenshots and implementation code are described. Finally, the 3D visualization simulation of the electric field process of 500kV multi-circuit transmission line with same tower is realized.
