Method for starting power station installation in deactivated electricity network, involves forming connection between generator of pressure store-relaxation turbine and start device of gas turbine group
A method for starting a power station installation in a deactivated electrical network, in which the power station comprises a pressurized air store (201) and a pressure store-relaxation turbine (203) and a gas turbo group (1). The procedure comprises opening a storage fluid mass flow adjustment element (7) and taking a storage fluid mass flow out of the pressurized air store. The storage fluid mass flow is then relaxed in the pressure store-relaxation turbine by generating a shaft output and then driving the generator (204) with the generated shaft output and generating a first electrical output. A connection is formed between the generator (204) and pressure store-relaxation turbine and a start device (22) of the gas turbine group. The gas turbo group is then started with the electrical power generated by the generator of the pressure store-relaxation turbine. An electrical connection is then made between the power station installation and the electricity network. An independent claim is also included for a power station installation.
