| description | A method for controlling a power plant which delivers electrical power to an electrical grid. This grid has a grid frequency which fluctuates around a nominal frequency (Fo). The power output of said power plant is controlled as a function of a control frequency, in such a matter that the power output is increased when the control frequency decreases below said nominal frequency (Fo), and in the other hand the power output is decreased when the control frequency increases beyond said nominal frequency (Fo). The grid frequency is continuously measured. The measured grid frequency (Fm) is averaged to give as a moving average a slowly varying averaged trend frequency which is charactersitic of the long term behaviour of the grid frequency. The averaged grid frequency is used as said control frequency, if said measured grid frequency (Fm) lies within a predetermined band, around said averaged grid frequency. The measured grid frequency (Fm) is used as said control frequency, if said measured grid frequency lies outside said predetermined band. |
