FIELD: mechanical engineering; gas-turbine plants. ^ SUBSTANCE: proposed method comes to measuring of gas pressure and temperature before power turbine, comparing measurands with maximum tolerable temperature t4tol before power turbine and regulating power output depending on obtained results, decreasing power output at exceeding of tolerable temperature values. Gas pressure and temperature are measured additionally after power turbine. When gas temperature before power turbine cannot be measured in case of failure of thermocouples located before turbine, operation of gas-turbine plant is continued, and temperature t4i of gas before power turbine is determined using equations protected by proposed invention. ^ EFFECT: prevention of untimely stopping of gas-turbine plant in case of failure of thermocouples measuring gas temperature before power turbine, provision of constant power output of plant. ^ 3 cl, 1 dwg |
