| Abstract: | A new module connection method has been proposed for numerical modeling of multi-loop pneuma- tic pressure power system(PPPS),and establishment of boundary conditions for pipelines,valves and tee joints.The numerical model of tee is solved using implicit method to settle the difficult tee modeling problem. A new algorithm has been developed for solving linear equations by combining LU's decomposition with SVD's least square method,and the model built is more accurate and stable.From the above research achievements, a PPTS modeling software has been successfully developed.A case study indicates that this software is relia- ble,and can further improve the modeling efficiency and quality. |
