Research And Application Of Computer Monitoring System ZHELIN Transformation

With the deepening reform of China’s market power, especially after separate power plants and grids。Hydroelectric power plant operations and management tend to be more commercial。Therefore, a need for more advanced and stable products and equipment to ensure reliable operation of the power plant economy, to create more efficiency for each power plant。Hydropower plant automation control system to meet the needs of current technological developments and power plants。Zhelin hydropower plant computer monitoring system after 10 years(A plant for 11 years, B works 9 years) of operation, taking into account the development of aging technology and computer monitoring system monitoring system equipment。Zhelin hydropower plant at the end of 2009 on the original decision to conduct a comprehensive monitoring system upgrading, automation and control using NARI Group’s SSJ3000 NC2000 system to replace the original operating system, and the host computer and lower computer hardware and software for comprehensive upgrading。Nanjing NARI Group uses the company’s automation and control system to replace the original SSJ3000 NC2000 operating system, and the host computer and lower computer hardware and software for comprehensive upgrading, canceled the original IPC LCU unit, directly through the PLC Ethernet port access PC system。Using A, B plant joint unified, all open, tiered distributed architecture. By stabilizing gradually upgrading so as to achieve enhanced system functions, optimizing the system structure, the purpose of improving the system reliability.Based on the domestic and international monitoring system development process research and analysis, combined with function Zhelin Hydropower original monitoring system shows the feasibility and necessity of transformation and upgrading of the proposed general principles of the system Zhelin Hydropower Plant Monitoring System and the transformation of the particular embodiment, briefed step measures of program implementation, and upgrade the performance of the new system after the completion of the transformation of the system were analyzed explained. With this upgrade, so that the monitoring system configuration and function has been greatly improved both in hardware and software, has laid a good foundation for the full realization of Zhelin hydropower "unattended"(less people on duty) requirements.
