The Lanxi Power Plant Coal Handling Control And Management System Development,

The modern thermal power plant has developed to apply ultra-supercritical units, and with the growing parameters of the capacity of the units, energy consumption for one time increased dramatically. If the safety of transporting burning coal into boiler system can't be guaranteed in the daily production process of thermal power plant, then the power system would generate less electricity or even stop generation. The economic loss in this case would be difficult to measure. How to transport, tansfer and store massive coal safly, efficiently and economically to ensure the power plants to use coal economically and orderly has become a major issue of auxiliary systems of new high-capacity thermal power plant. The control and management of the coal handling system was also carried out simultaneously by Zhe Neng Lanxi power plant in the infrastructure construction.The paper mainly takes analysis on system requirements of coal controlling and transporting management of Lanxi Power Plant, which including system tasks, objectives, compositions, control requirements, network requirements, real-time monitoring requirements, daily management and security requirements and so on. On the basis of the design of system overall structure, network structure, hardware configuration, control system software, etc., Lanxi Power Plant takes parts of typical modules production by taking advantage of third-party software. As a result, it develops a reasonable, safe, highly effective and reliable coal-transporting control management system. At last, the paper gives the summarization of the whole project performance history and forecasts to the future development. In the appendix, it states some of human-computer interface realized by this system.The Lanxi Power Plant successfully develops coal-transporting control management system, which realizes the intensive and automatic control of the whole process as: burning coal transportation, allocation, sampling, measurement and protection, etc. In this way, work efficiency is greatly improved. Operators'work intensity of work is lightened. Coal-transporting control management is enhanced to a new level.
