Power station and method for its operation

摘要

A power station (10) is provided having a turbine shafting (11) including a gas turbine (12) and a generator (18) which is driven directly by the gas turbine (12), produces alternating current at an operating frequency and whose output is connected to an electrical grid (21) with a predetermined grid frequency. An electronic decoupling apparatus or a variable electronic gearbox (27) is arranged between the generator (18) and the electrical grid (21), and decouples the operating frequency from the grid frequency.

主权项

1. A power station having a turbine shafting comprising:
a gas turbine and a generator which is driven directly by the gas turbine, that produces alternating current at an operating frequency and whose output is connected to an electrical grid with a given grid frequency, wherein a variable electronic gearbox is arranged between the generator and the electrical grid to facilitate power from the generator being output to the electrical grid and to control a rotation speed of the gas turbine, wherein the variable electronic gearbox of the gas turbine is configured to impose the rotation speed on the gas turbine via a conversion ratio between a mechanical rotation speed of the gas turbine and the grid frequency via the generator to facilitate the output of power from the generator to the electrical grid and to thereby control the rotation speed of the gas turbine.
