摘要： A gas turbine engine control method and apparatus as disclosed for optimizing fuel/air mixture, especially during decreasing load conditions. In a large capacity gas turbine engine system used for generation of electric power, the system is designed to operate at a relatively constant rotational speed of the turbine which drives an electric generator unit. The load of the turbine engine varies throughout the day due to changes in electrical power demands. During normal rated load conditions, the control of the fuel/air mixture is by way of changes in fuel supply, corrected to return the turbine exhaust temperature to a desired rated temperature. During this mode of operation, the compressor inlet guide vanes are maintained in a substantially constant open position. For accommodating decreasing load conditions where the temperature drops below a predetermined temperature level below the rated temperature operation, the system is switched to an inlet guide vane control mode of operation. During the guide vane control mode of operation, the inlet guide vanes are controlled at a more precise temperature correction sensitivity than is the case for normal load operations. This more precise inlet guide vane control during decreasing load conditions assures improved fuel/air mixture during decreasing load and consequent improved efficiency and minimal NO.sub.x compound emissions, especially during changing ambient temperature conditions where cold air would otherwise increase the air supply.
摘要翻译： 公开的用于优化燃料/空气混合物的燃气涡轮发动机控制方法和装置，特别是在减小负载条件下。 在用于产生电力的大容量燃气涡轮发动机系统中，该系统设计成以驱动发电机单元的涡轮机的相对恒定的转速运行。 由于电力需求的变化，涡轮发动机的负载在一整天内变化。 在正常的额定负载条件下，燃料/空气混合物的控制是通过燃料供应的变化来进行的，这被校正以将涡轮排气温度恢复到所需的额定温度。 在这种操作模式下，压缩机入口导叶保持在基本恒定的打开位置。 为了适应温度下降到低于额定温度运行的预定温度水平的降低负载条件，系统被切换到入口导叶控制操作模式。 在导叶控制操作模式下，入口导流叶片的控制精度比正常加载操作更为精确。 在降低负载条件下，这种更为精确的入口引导叶片控制确保了在减少负载的同时改善了燃料/空气混合物，从而提高了效率和最小化的NOx化合物排放，特别是在其他空气会增加空气供给的环境温度变化的环境中。

摘要： A control method of a gas turbine which is provided with a multi can type combustor consisting of a plurality of unit combustors, each of which has a first stage combustion section for diffusion combustion and a second stage combustion section for premix combustion. Combustion states in the first and second stage combustion sections are monitored to take in quantities representative of the combustion conditions as control factors. The combustion in the second stage combustion section is assumed to be abnormal when the taken in quantities exceed an allowable limit and the combustion in the first and second stage combustion sections is changed to independent combustion only in the first stage combustion section when the number of unit combustors, each of which is assumed to be abnormal, exceeds a predetermined number of the unit combustors.

摘要： A fuel supply amount is controlled while the load of a gas turbine is changed so that the fuel supply amount is shifted to a fuel supply amount in accordance with the changed load. A fuel supply control valve is operated at high speed during an initial stage and operated at a lower speed as the fuel supply amount necessary for the changed load is reached. Therefore flameout of a combustor is prevented without increasing the number of revolutions of the gas turbine over a certain upper limit.

摘要： A method and apparatus that prevent degradation of an image quality due to a change of a beam pitch in a subscanning direction of each optical beam on a record medium. At a given time, for example, when power is first turned on, a CPU detects a beam pitch on a record medium, e.g., a photosensitive drum, by using a CCD line image sensor. If the detected value differs from a value set according to a currently-selected scanning density, an LD arrangement change motor is rotated via a motor driver so that the beam pitch matches the set value so as to change an arrangement of laser diodes in a laser diode array. Control over the beam pitch occurs for a variety of conditions including control at regular intervals, power-on events, or when a scanning density specification signal indicates a different beam pitch than the detected beam pitch. Similarly, adjustment over the beam pitch is not typically made during a copying operation.
