Abstract
A device for control of power (P) generated by a gas turbine (1) which drives an electric generator (2) with a rectifier (3) connected thereto, comprises a control member (6) adapted to control the fuel supply of the gas turbine (1) in such a way that the inlet temperature (T) of the gas turbine is caused to correspond, at least substantially, to a predetermined value (TR). A direct-voltage network (4) with controllable voltage (U) is connected to the rectifier (3) and the control member (6) generates a voltage control signal (URs) which is supplied to the direct-voltage network (4) .
Claims28
A method for control of power generated by a gas turbine which drives an electric generator with a rectifier connected thereof, a direct-voltage network with a controllable voltage being connected to said rectifier, the gas turbine having a fuel supply and a temperature sensing means for sensing the inlet temperature of the gas turbine, comprising the steps of:
- sensing said inlet temperature;
- controlling said fuel supply so that said inlet temperature is caused to substantially correspond to a predetermined value;
- and
- varying said controllable voltage to control said power.
A method for control of power generated by a gas turbine which drives an electric generator with a rectifier connected thereto, a direct-voltage network with a controllable voltage being connected to said rectifier, said direct-voltage network comprising a direct-voltage converter for controlling the voltage of said network, the gas turbine having a fuel supply and a temperature sensing means for sensing the inlet temperature of the gas turbine, comprising the steps of:
- sensing said inlet temperature;
- controlling said fuel supply so that said inlet temperature is caused to substantially correspond to a first predetermined value;
- and
- varying said controllable voltage to control said power.
