METHOD FOR ADJUSTMENT OF COMPRESSOR STATION Russian patent published in 1997 - IPC

FIELD: gas compressor stations. SUBSTANCE: method relates to compressor stations made up of several dynamic compressors. According to method, regulator of station adjusts main parameter of gas by increasing or reducing output capacity of station to restore main parameter of gas to required level. Initially it is made by simultaneous changing of operation of all individual compressors for example by reducing their speed and then after working points of all compressors reach their corresponding lines of setting antisurging adjustment, by simultaneous opening of all antisurging valves. In proposed load distribution scheme, one compressor is automatically chosen as leading one. In parallel operation, that compressor which is chosen as leading one is of longest distance from corresponding line of setting antisurging adjustment. At series operation, leading compressor has lowest value of criterion determined by distance to line of setting antisurging adjustment and equivalent mass flow through compressor. Leading compressor is followed by remaining ones so as to equalize their distances to corresponding lines of setting antisurging adjustment or criteria R with values corresponding to those of leading compressor. EFFECT: high efficiency. 5 cl, 4 dwg
