Architecture Construction And Application Of SCADA System In The Kunlun Gas

Kunlun Gas Transmission and Distribution network, between the surge tank, measuring tank, metering service providers, CNG stations geographically dispersed, remote station, a vast, such as the use of artificial form for each station(box) to monitor, step by step methods of reporting, there are reported data is not timely, equipment failure that is not timely and other security risks. Building a SCADA system, on-site production data acquisition and real-time monitoring and dispatch control of the production process, the gas transmission and distribution, transportation process real-time monitoring and control, timely detection and treatment spill, according to the actual needs of end users will be gas scheduling assignment,to improve gas supply, transmission and distribution of rationality and stability. Natural gas pipeline network scheduling departments to enhance network performance monitoring,improve work efficiency and quality, ensure safety in production, auxiliary production operations and emergency decision-making and improve the economic and social benefits play a significant role in promoting.From the alarm system management, HMI(Human Machine Interface) development management, control room SCADA system at all levels of construction, station SCADA system construction, system configuration database, data communication system and other aspects of the structure and function of the overall construction of the SCADA system was studied describes the application of the Kunlun gas company, as well as the effect of the SCADA system made in the application process in. Built SCADA production command system, will complete the monitoring of each remote field, scheduling management and optimize the operation of other tasks. Each station RTU systems operate independently under normal conditions, data acquisition and processing station, to produce command and control center to upload the collected various data and information, RTU also perform command and control center instructions to achieve the production of field instrumentation control effect.Set up monitoring, dispatch management terminal manned station(CNG station), once the data communication system or a superior system failure, a timely alarm and automatically switch to safe mode state local control.
