【摘要】：随着我国电力市场改革的不断深入,尤其是电厂和电网分开后,水力发电厂的运营和管理更趋向于商业化,因此也需要有更先进、稳定的产品和设备保证电厂的经济可靠运行,给各个发电厂创造更多的效益,水电厂自动化监控系统满足了目前技术发展和发电厂的需要。柘林水电厂计算机监控系统在经过10年左右(A厂11年,B厂9年)的运行后,由于监控系统设备逐年老化以及计算机监控系统新技术的不断发展,柘林水电厂经过讨论研究决定于2009年对原监控系统的软、硬件进行升级改造,选用南京南瑞集团自动化控制公司的NC2000系统取代原SSJ3000操作系统,并对上位机及下位机硬件及软件进行全面的更新换代,取消A厂现地控制单元的工控机部分,改为直接通过PLC自带的以太网接口接入上位机。采用A、B厂联合统一、全开放,分层分布式结构。通过此次升级改造达到提高系统可靠性、增强系统功能、优化系统结构的目的。本文从国内外监控系统的发展过程着手,进行了深入的研究和分析,结合柘林水电厂原监控系统的功能,说明了改造的可行性及必要性,并提出了柘林水电厂监控系统升级改造的系统总体原则及改造的具体实施方案,介绍了方案实施的步骤措施等情况,并对新系统升级改造完成后的系统各项性能进行了分析说明。通过此次升级改造,使得监控系统在软硬件配置及功能上均得到了大幅提高,为柘林水电厂全面实现“无人值班”(少人值守)的要求奠定了良好的基础。
[Abstract]:With the deepening of China's electricity market reform, especially after the separation of power plants and power grids, the operation and management of hydropower plants tend to be commercialized. Therefore, more advanced and stable products and equipment are also needed to ensure the economic and reliable operation of power plants. The automatic monitoring system of hydropower plant meets the needs of current technology development and power plant. After about 10 years' operation of the computer monitoring system in Zhelin Hydropower Plant (A Plant 11 years and B Plant 9 years), the monitoring system equipment is aging year by year and the new computer monitoring system technology is developing continuously. After discussion, Zhelin Hydropower Plant decided to upgrade the software and hardware of the original monitoring system in 2009. The NC2000 system of Nanjing Nanrui Group Automation Control Company was chosen to replace the original SSJ3000 operating system. The hardware and software of the upper computer and the lower computer are completely updated, and the industrial computer part of the field control unit in factory A is cancelled, and the PC is connected directly through the Ethernet interface provided by PLC. Adopt AZB factory United, all open, hierarchical and distributed structure. The purpose of this upgrade is to improve the system reliability, enhance the system function and optimize the system structure. This paper starts with the development process of monitoring system at home and abroad, carries on the thorough research and analysis, combined with the function of the original monitoring system of Zhelin Hydropower Plant, explains the feasibility and necessity of the transformation. In addition, the general principles of the system upgrading and transformation of the monitoring system in Zhelin Hydropower Plant and the concrete implementation plan of the transformation are put forward, and the steps and measures for the implementation of the scheme are introduced. The performance of the new system after upgrading and upgrading is analyzed and explained. Through this upgrade, the hardware and software configuration and function of the monitoring system have been greatly improved, which lays a good foundation for the full realization of the requirement of "unmanned duty" in Zhelin Hydropower Plant.
