Abstract

The invention discloses a measurement management method and device for a natural gas storage and transportation system, which belongs to the technical field of natural gas pipeline storage and transportation management. Obtain the first data of real-time measurement of each pipe section in the natural gas storage and transportation system through the data acquisition and monitoring control SCADA system; obtain the second data of the measurement handover and report of each pipe section in the natural gas storage and transportation system through the pipeline production management PPS system; according to the The first data of each pipe section and the second data of each pipe section calculate the loss value of each pipe section; determine the loss threshold of each pipe section according to the actual business; according to the loss value of each pipe section and For the loss threshold of each pipe section, select the pipe section with abnormal loss value from the various pipe sections; and give an alarm to the pipe section with abnormal loss value. The invention realizes the analysis and early warning of the transmission loss value of the pipeline section, and provides support for improving the measurement management level of the natural system storage and transportation pipeline network.

Description

technical field [0001] The invention relates to the technical field of natural gas storage and transportation management, in particular to a measurement management method and device for a natural gas storage and transportation system. Background technique [0002] With the progress of the times and the improvement of people's living standards, natural gas has been widely used as a clean energy; the construction of natural gas storage and transportation systems has developed rapidly, and the scale of the system has become very large. A trunk line includes a plurality of branch lines, and each branch line in the plurality of branch lines can include a plurality of pipe sections, and each pipe section in the plurality of pipe sections includes a plurality of stations, and each station in the plurality of station yards includes a plurality of pipe sections. distribution node. Therefore, how to standardize and scientifically carry out the metering management of the natural gas s...
