METHOD FOR CONTROL OF COMPRESSOR SHOP Russian patent published in 2016 - IPC F04D27/00 

FIELD: measurement technology.

SUBSTANCE: invention relates to operation of shop controls in compressor workshops compressor stations. In control method of compressor shop, which involves control of fuel gas consumption, load is changed in turn groups GCU, operating in line, for which two GCU group simultaneously change of rotation frequency of low-pressure turbine rotors in opposite directions at equal value. For neutralising effect of noise on measurement efficiency software filters are applied with large time constants. Measurement of changed efficiency is performed after time delay, exceeding at least 3…5 times of maximum time constant of filters. Direction of each rotor rpm change pitch of low pressure turbines is determined by the sign of increment efficiency obtained at previous step, the end of optimisation of the group is considered small increment efficiency or approximation of working point GCU to process limitation.

EFFECT: reduced consumption of fuel gas, higher efficiency of compressor shop.
