ABSTRACT:
The proposed method for automatic control of a power plant is as follows. A control signal of the electric generator's electric load is applied to a first control element which controls the flow of gas supplied from the gas line to the high-pressure section of an expansion engine. This controls the amount of gas directed from the take-off chamber of the expansion engine to the gas pipeline. A control signal to control the pressure downstream of the expansion engine is applied to a second control element to control the flow rate of the gas flow directed from the low-pressure section of the expansion engine to the controlled counter-pressure line. A control signal to control the pressure downstream of the expansion engine is applied to a third control element to control the gas flow rate, which is installed in the line that bypasses the low-pressure section of the expansion engine, whereby the rest of the gas flow is directed to the controlled counterpressure line. The proposed power plant of a compressor station of a gas pipeline system with gas mains and gas pumping units including gas compressors and combustion chambers of gas turbine installations, wherein the proposed method is realized, comprises an electric generator intended to meet the power requirements of the compressor station and an expansion engine having a high-pressure section, a pressure chamber and a low-pressure section. The shaft of the expansion engine is coupled to that of said electric generator. The first control element is installed at the inlet of the high-pressure section of said expansion engine. A check valve is installed at the outlet of the take-off chamber of said expansion engine. The second control element is installed at the inlet of the low-pressure section of said expansion engine. In the line that bypasses the low-pressure section of said expansion engine there is installed the third control element. The power plant further includes a cooler of gas discharged from said take-off chamber of said expansion engine. The inlet of the high-pressure section of said expansion engine is connected through a heater and the first control element to the gas main; the outlet of the take-off chamber is connected through the check valve to another portion of the gas line; the outlet of the low-pressure section is connected to the combustion chambers.
