【摘要】：华能西藏发电有限公司(简称华能西藏公司)是水电站为主的区域发电公司,公司主要针对雅鲁藏布江流域梯级电站进行开发。本文以建设国内先进的集控中心系统为目标,通过前期对国内大型水电站集控的调研,借鉴国内外先进技术,提出在区域第一个电站建设初期就在藏木业主营地建设藏木扩大厂站中控室(山南集控中心)对雅鲁藏布江流域中游街需、藏木、加查水电站进行集中控制;同时在华能西藏公司林芝基地建设雅鲁藏布江流域林芝集控中心对雅鲁藏布江中下游梯级电站进行集中监控;并在成都建设成都运营管理及技术支持中心对华能西藏公司在藏所有电站实施远方监控的雅鲁藏布江流域大型远程集控方案,从而节约工程建设投资,减少运行人员配置,改善生产管理人员工作环境。结合以山南集控中心、林芝集控中心及成都运营管理及技术支持中心构成的远程集控方案,本文就该种模式下流域集控中心的综合自动化系统进行研究,确定综合自动化系统的构成,建立系统安全防护体系,完成系统组网及带宽分配。同时,为实现电站安全、稳定、经济的生产运行需要,适应“无人值班”的现代化水电站生产管理模式,满足现代化数字电站所必须的集中调度管理、分布式网络控制要求,本文提出基于雅鲁藏布江流域梯级电站全开放、分布式的综合自动化系统整体解决方案。文中建立了包括计算机监控系统、数据交换系统、消防监控系统、工业电视系统、通信系统等综合自动化系统主要子系统的总体结构,完成了相应系统的功能及设备配置。本文研究的亮点在于:(1)在国内大江大河干流上首个电站建设之初,就对整个流域的远程集控进行规划,集控中心与首个电站首台机组同时投运。(2)在国内大型水电站建设时现场就不设置中控室和计算机监控系统上位机。(3)确定了公司建设“无人值班电站群(即关门运行电站群)、远程集控”的建设标准以及今后公司电站的管理模式。本文通过对雅鲁藏布江流域远程集控方案及集控中心综合自动化系统的研究,基本完成了流域远程集控系统的设计与规划,为电站集控建设降低成本、优化人员配置、改善工作环境和稳定职工队伍提供基础,同时也为西藏地区大型水电站的开发提供实践经验。
[Abstract]:Huaneng Tibet Power Generation Co., Ltd (Huaneng Tibet Company) is a regional power generation company based on hydropower stations, which mainly aims at the development of cascade power stations in the Brahmaputra River basin. This paper aims at constructing the advanced centralized control center system in China. Through the investigation and research on the centralized control of large hydropower stations at home and abroad, the paper draws lessons from the advanced technology at home and abroad. It is put forward that in the early stage of construction of the first hydropower station in the region, the central control room (central control center of Shannan centralized control center) will be built in the main site of the Tibet timber industry to control the Yalu Zangbo River valley in the middle street, Tibetan wood, and Jiacha hydropower stations. At the same time in Huaneng Tibet Company Linzhi base construction of Yalu Zangbo River Basin Linzhi centralized control center to the middle and lower reaches of the Brahmaputra cascade power station centralized monitoring; And to build the Chengdu Operation Management and Technical support Center in Chengdu to implement a large-scale remote centralized control scheme for Huaneng Tibet Company to monitor all power stations in Tibet remotely, so as to save construction investment and reduce the number of operational personnel. Improve the working environment of production managers. Combined with the remote centralized control scheme composed of Shannan centralized control center, Linzhi centralized control center and Chengdu operation management and technical support center, this paper studies the integrated automation system of watershed centralized control center under this mode. The composition of the integrated automation system is determined, the system security protection system is established, and the system network and bandwidth distribution are completed. At the same time, in order to realize the safe, stable and economical operation of the power station, adapt to the production management mode of the modern hydropower station with "no one on duty", and meet the requirements of centralized dispatching management and distributed network control for the modern digital power station, In this paper, an overall solution of integrated automation system based on Yalu Zangbo River basin cascade power station is proposed. In this paper, the overall structure of the main subsystems of the integrated automation system, including computer monitoring system, data exchange system, fire control system, industrial television system, communication system and so on, is established, and the function and equipment configuration of the corresponding system are completed. The bright spot of this paper is that at the beginning of the construction of the first power station on the main stream of the great rivers in China, the remote centralized control of the whole river basin was planned. The centralized control center and the first unit of the first power station were put into operation at the same time. In the construction of large hydropower stations in China, the central control room and the computer monitoring system were not set up in the field. The "unattended power station group" (that is, closed operation) was determined. Construction standard of power station group, remote centralized control and management mode of power station in the future. In this paper, the design and planning of remote centralized control system of Yalu Zangbo River basin and the integrated automation system of centralized control center are basically completed, which can reduce the cost and optimize the personnel allocation for the centralized control construction of the power station. Improving the working environment and stabilizing the work force provide the basis for the development of large hydropower stations in Tibet.
