Abstract

In the case of known control methods, faults which give rise to intervention by the governor, for safety reasons operating at increased proportional boosting, result temporarily in reduced surge reliability of the compressor and in prolonged, periodic pressure fluctuations in the consumer mains post-connected to the compressor. The new control method is intended to avoid these disadvantages. <??>The new control method is characterised in that in the event of a discrepancy between the position (ya) of the venting valve (21) and the control variable (u) of the governor (5) exceeding a predeterminable limit, the control variable (u) of the governor (5) is readjusted to the respectively current position (ya) of the venting valve (21) by a readjusting circuit (9). In this way transient processes and hence related reductions in the pumping reliability and longer pressure fluctuations are avoided. <??>The new method is suitable in particular for the control of large turbocompressors, for example for blast furnace blast generation, air separation, fertilizer manufacture or fluidised bed generation for petrochemical processes.
