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 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, the Compressor Discharge Chamber (CDC), and/or the combustion system 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. The injected diluent is microprocessor controlled to either be simultaneous into all three circuits or is sequenced based on a determination of the best turbine control and performance.
摘要翻译：提供了一种通过提供快速响应功率增加系统来改善燃气轮机的低频响应的系统和方法。该系统包括储存燃料如乙醇或甲醇的混合混合物和预定比例的软化水的罐，其作为要注入压缩机喇叭口的稀释剂，压缩机排放室（CDC）和/或燃烧系统通过一到三个专用电路。为了实现在正确压力下的适当持续时间的稀释剂的瞬时注入，以满足燃气轮机电网顺应性要求的需要，使用蓄能器作为驱动专用电路中的增压流体的动力。喷射的稀释剂是微处理器控制的，以便同时进入所有三个电路，或者基于确定最佳涡轮机控制和性能进行排序。

摘要： A system and method for supercharging a combined cycle system includes a forced draft fan providing a variable air flow. At least a first portion of the air flow is directed to a compressor and a second portion of the airflow is diverted to a heat recovery steam generator. A control system controls the airflows provided to the compressor and the heat recovery steam generator. The system allows a combined cycle system to be operated at a desired operating state, balancing cycle efficiency and component life, by controlling the flow of air from the forced draft fan to the compressor and the heat recovery steam generator.
