Criteria's of iterative procedure interrupt at calculation of gas distribution network with loops
AbstractGas distribution networks are calculated today usually so that its pipes are formed several annular loops. These networks are ensured certainly providing of consumers, but they have to be calculated after iterative procedure (mostly HardyCross). Iterative procedure is used because here are existed three unknown parameters, and only two equations can be written. In this paper are considered two parameters of calculation accuracy which utilize for iterative procedure interrupt on the realistic example of network: (square of) algebraic addition of pressure by the loops and repairing flow by the loops. Also, here was shown recommendation for values of accuracy parameters for usual networks size.
