| Abstract: | In the natural gas transmission system,the inlet pressure of offtake-point changes with the consumption of the downstream and the flow in the pipeline.We can judge whether the inlet pressure is normal through comparing the calculated pressure values and the measured pressure values in the SCADA system,it has the advantages of simplicity,intuition and high accuracy |
