The invention relates to the branch of turbine building and relates to systems for turbo-expanders control. The system for turbo-expander control, installed at the line of pipeline in parallel to gas-distribution station, between the mains of high and low pressure gas, has unit for system control, executive control valve and stop valve at gas inlet to turbo-expander, and bypass block installed in parallel to the pipeline line with turbo-expander. Bypass block has membrane controller of gas pressure, its membrane is connected to the output of the turbo-expander, and flow rate valve, this is controlled by membrane controller, and valve for protection, and appliance for connection and disconnection of bypass block connected to the unit for system control. The invention with reliability and stability provides standard parameters of gas for consumer in the case of emergency disconnection of turbo-expander.
