摘要： A valve control device (50) controls the degree of opening of a pressure adjust-ment valve (44), and is provided in a gas turbine (12), which is equipped with: a combustor (22) that generates combustion gas by burning a fuel; a turbine (24) driven by the combustion gas gen-erated by the combustor (22); a flow volume and-justment valve (42) that adjusts the flow volume of the fuel supplied to the combustor (22); and the pressure adjustment valve (44) that adjusts the fuel pressure and is arranged upstream from the flow volume adjustment valve (42) in a fuel flow path (40) that supplies fuel to the combustor (22). The valve control device (50) is equipped with a load reduction detection unit (52), which detects a reduction in the load of the gas turbine (12), and a pressure control unit (56) which, when a load reduction has been detected by the load re-duction detection unit (52), controls the degree of opening of the pressure adjustment valve (44) in response to the output of the gas turbine (12) after the load reduction. Thus, the valve control device (50) prevents unstable output from the gas turbine even when the load decreases sharply.
摘要翻译：阀控制装置（50）控制压力调整阀（44）的开度，设置在燃气轮机（12）中，该燃气轮机具备：通过燃烧而产生燃烧气体的燃烧器（22）燃料; 由燃烧器（22）产生的燃烧气体驱动的涡轮机（24）; 流量调节阀（42），其调节供给至燃烧器（22）的燃料的流量; 和调节燃料压力的压力调节阀（44），其设置在向燃烧器（22）供应燃料的燃料流路（40）内的流量调节阀（42）的上游侧。阀控制装置（50）具备检测燃气轮机（12）的负荷降低的负荷降低检测部（52）和压力控制部（56），压力控制部（56）在负荷降低时由负载减少检测部（52）检测到的负载减少后的燃气轮机（12）的输出对应于压力调整阀（44）的开度。因此，即使当负载急剧下降时，阀门控制装置（50）也防止燃气轮机的不稳定输出。
