摘要： An object is to reduce a fluctuation in the gas-turbine output in a nozzle switching period. In the nozzle switching period during which a first nozzle group that has been used is switched to a second nozzle group that is going to be used, the amounts of fuel supplied through the first nozzle group and the second nozzle group are adjusted by using at least one adjustment parameter registered in advance, the adjustment parameter registered in advance is updated according to the operating condition of the gas turbine, and the updated adjustment parameter is registered as an adjustment parameter to be used next.

摘要： A fuel control method for a gas turbine with a combustor being formed of at least two groups of a pluralities of main nozzles for supplying fuel, and that supplies fuel from the main nozzles of all groups upon ignition of the combustor (S1), and supplies fuel from three main nozzles of a group A during subsequent acceleration of the gas turbine (S3). Because fuel is injected from a small number of the main nozzles during acceleration, the fuel flow rate per one main nozzle is increased, thereby increasing the fuel-air ratio (fuel flow rate/air flow rate) in a combustion region and improving the combustion characteristics. Accordingly, the generation of carbon monoxide and unburned hydrocarbon is reduced, whereby no bypass valve is required and manufacturing costs are reduced. Because fuel is supplied from the main nozzles of all groups and burned in the entire area of the combustor upon ignition, it is possible to easily propagate a flame to all the other adjacent main nozzle groups, thereby improving the ignition characteristics of the whole gas turbine.
摘要翻译： 一种用于具有燃烧器的燃气轮机的燃料控制方法，所述燃气轮机由至少两组用于供应燃料的主喷嘴组成，并且在燃烧器（S1）点火时从所有组的主喷嘴供应燃料，并且供应 在燃气轮机的后续加速期间来自组A的三个主喷嘴的燃料（S3）。 由于在加速期间从少量主喷嘴喷射燃料，所以每个主喷嘴的燃料流量增加，从而提高燃烧区域的燃料空气比（燃料流量/空气流量），提高燃烧 特点 因此，一氧化碳和未燃碳氢化合物的产生减少，由此不需要旁通阀并且降低制造成本。 因为燃料从所有组的主喷嘴供应并且在点火时在燃烧器的整个区域燃烧，所以可以容易地将火焰传播到所有其他相邻的主喷嘴组，从而提高整个燃气轮机的点火特性 。

摘要： A fuel-flow-rate control device, a power generation system, and a fuel-flow-rate control method which can prevent overshooting of a gas turbine output (gas turbine inlet temperature) and which can improve power generation efficiency are provided. The fuel-flow-rate control device includes a computing portion for obtaining a state quantity relating to operating conditions and temperature conditions of a gas turbine as an input signal and computing a fuel-flow-rate command for controlling a fuel flow rate supplied to a combustor based on the above input signal, and a second selection circuit for setting the above fuel-flow-rate command to be not more than a fuel-flow-rate upper limit. The fuel-flow-rate upper limit is a fuel flow rate at which the gas turbine inlet temperature is set to be not more than a predetermined upper temperature limit.
