Nam Theun Mine Coal Handling System, Automatic Control And Information Design And Realization

Along with the development of automation technology, power plants increasingly high degree of automation, to create an efficient, clean, safe and reliable power plant automation system is a general trend. NanTun Power Plant as a mine-owned power plant due to production Yankuang earlier, the relative degree of automation is not high. With the power plant four projects forward, Coal transport system as a Power Plant, one of the most critical systems, equipment and more control over complex, long-running, so a higher degree of design of a modern performance and better coal handling automatic control system is necessary.In addition, NanTun plant are planned to complete the entire plant production information system. Coal Handling Control System will become part of it, rather than an information island, for which the new design of the "HuaJu NanTun Power Plant Coal Mine Automation Control System" will also be a good degree of information technology systems to achieve information sharing.NanTun Power Plant Coal Mine under the automatic control system requirements and the whole plant information management requirements, design, and leave with PROFIBUS Fieldbus Industrial Ethernet interfaces. The system mainly consists of three parts: automatic control systems, industrial TV monitoring system, an integrated belt machine protection system. Main completed NanTun Power Plant Coal Mine Automation.Part of the automatic control system for transporting coal using Siemens PLC S7-3152DP-based station, the sub-station using EM277 Remote I / O, use of PROFIBUS field bus connection; belt machine integrated protection systems with access to the remote I / O points station, to realize slipping belt machine, deviation, ultra-temperature, smoke, piles of coal, and pull emergency stop and other protection; industrial television monitoring equipment, assist-control personnel on-site monitoring, reproduced the main point, under the port and other key positions is expected to video surveillance, making the system truly on-site unattended, reducing the workload of staff. The design emphasis on the practical, advanced, several aspects of reliability, and has been put into field use, running well.
