Distributed computer monitor management system transformer stations birth |
|
Recently, the University of Science and Technology and Shandong Yanzhou Mining (Group) Company Jining 2nd Coal Mine in the operation in the coal industry substations, transformer stations using a distributed computer monitor management system for safety in production and scientific management of great significance. Distributed control system (DCS) is based on computer technology, control technology, communications technology and graphical display techniques (4C technologies), through a communications network will be deployed in the industrial scene control stations (substations), testing stations, control the management, engineers stations linked to the completion of decentralized and centralized control of the operation, and management of integrated control systems. Distributed computer network computer technology and communications technology in recent years mutual penetration of a door to the rapid development of new technologies, which concentrated on contemporary computer hardware, software and communications technology development results, a good adaptable. The hardware structure is simple, user-friendly operation, easy to expand and maintenance, users can choose according to the different needs of the system. Jining 2nd Coal Mine 110kV substations huge system, the introduction of double circuit power. Outdoor 110kV double bus bar contact and the use of dedicated road bus bar, 2, 3 Coal Mine Road 110kV project to Jining, three main transformers Taiwan 12500kVA assume all mine load. 110kV circuits with protection, the protection of parallel lines, distance protection, poor bus bar protection relay home, and the main transformers had loads, composite voltage electric current, light gas, vertical deviation, zero sequence direction relay. 6kV fed fresh Chun room with a flexible protection 6kV 43 Taiwan-cabinets, including six Taiwan into line cabinets, four Taiwan Liaison cabinets, one Taiwan lightning arrester at 32 Taiwan fed fresh cabinets, a small bus bar, double bus bar above. The transformer stations distributed computer monitor management system with the following functions : detection 110kV circuit into two lines, Jining 3 Coal Mine Road project and two main transformers at the current, voltage, Yougonggonglu:, no credit power, meritorious electricity, no credit sales, Fengyu electricity and power factor ;6kV room various sub-disc currents, voltage, capacity; simulation of the sequence of events by the police and records; switches division instructions, the nature of the accident Tiaozha instruction, simulation chart.
