METHOD FOR FREQUENCY STABILISATION OF ELECTRIC MAINS Russian patent published in 2014 - IPC F01K13/02 

FIELD: electricity.

SUBSTANCE: invention is related to the method for frequency stabilisation of electric mains. A two-shaft gas turbine consists of a powerful turbine and a gas generator, at that the powerful turbine is connected to the first generator by the first shaft in order to transmit torque. The invention also refers to a device for implementation of this method. Conventional methods of frequency stabilisation have high investment costs and efficiency losses. In order to solve these problems the invention envisages that the first shaft of the powerful turbine and the first generator is rotated permanently synchronically with the electric mains, and the first generator is driven as the engine while the second shaft of the gas generator is rotated permanently with a number of cranking rpm, at that at the power request the gas generator is started up and the powerful turbine is driven by hot gas generated by the gas generator so that the first generator generates electrical current.

EFFECT: invention allows increase in efficiency and economic feasibility of the mains frequency stabilisation.
