| 20090277183 | PRIMARY FREQUENCY REGULATION METHOD THROUGH JOINT CONTROL IN COMBINED CYCLE TURBINES - A method for providing Asymmetric Joint Control for Primary Frequency Regulation (PFR) in combined cycle power generation plants, said plant comprising at least one gas turbine and at least one steam turbine is provided. The method may comprise the use of the spinning energy existing in the high pressure steam to rapidly supply additional power to the steam turbine for PFR service when required by the grid, within the time frame established as a requirement to participate in the PFR service,. In some embodiments, PFR control can be carried out jointly in the whole combined cycle plant and the distribution of spinning reserve energy can be asymmetric. | 11-12-2009 |
