    摘要: A system and method is provided that improves the under frequency response of gas turbines by providing a fast-response power augmentation system. The system includes a tank (102) storing a blended mixture of motive fuel such as ethanol or methanol and demineralized water in a predetermined ratio that is provided as a diluent to be injected into the compressor bellmouth (136), the Compressor Discharge Chamber (CDC) (138), and/or the combustion system (140) via one to three dedicated circuits. To achieve the instantaneous injection of the diluent at the correct pressure and for the appropriate duration to meet the needs of the gas turbine Grid compliance mandate, an accumulator is used as the motive force to drive the augmentation fluid in the dedicated circuits (134). The injected diluent is microprocessor controlled to either be simultaneous into all three circuits (134) or is sequenced based on a determination of the best turbine control and performance.
