FIELD: systems for controlling single-shaft turbine generator plants used for producing thermal and electrical energy, namely, single-shaft turbine generator plants with thyristor frequency transformer. ^ SUBSTANCE: in the method for controlling single-shaft turbine generator plant with static frequency transformer, for every controlled parameter control signals are generated using parameter regulator, values of these signals are compared, signal with least value is selected, and that output signal is used to regulate executive organ of an object, additional control signal is generated on basis of proximity to extreme allowed values of at least one parameter used for generation of output signal for controlling fuel injection and at least one parameter which is not used for generating output signal for controlling fuel injection, aforementioned additional control signal is sent to active power regulator and to system for controlling static frequency transformer to reduce power, outputted by static transformer into electrical network, according to given rule, and to remove parameters from the zone of proximity to extreme allowed values. ^ EFFECT: possible long-term stable operation in common or parallel electrical network with output of power through thyristor frequency transformer in modes close to extreme for one-shaft gas turbine motor; during operation of one-shaft turbine generator plant in autonomous mode, additional control signal is used for reducing the load by managing load switches of low priorities and by removing parameters from zone of proximity to extreme allowed values. ^ 2 cl, 1 dwg |
