摘要： In one embodiment, a heat storage power generation system includes a heater to heat first fluid, and a heat storage to be heated by the first fluid, and heat second fluid with heat stored in the heat storage. The system further includes a generator to generate electric power by using the second fluid, a heating controller to control heating of the first fluid by the heater, and a power generation controller to control power generation performed by the generator. The heating controller controls the heating of the first fluid, based on two or more limit values among a first limit value related to an amount of energy consumption by the heater, a second limit value related to temperature of the first fluid, a third limit value related to internal temperature of the heat storage, and a fourth limit value related to a change rate of the internal temperature.

摘要： In one embodiment, a thermal energy storage power plant includes a thermal accumulator to accumulate thermal energy and heat a thermal medium with the thermal energy, and a steam generator to generate steam using the thermal medium. The plant further includes a first path to convey the thermal medium from the accumulator to the generator, and a second path to convey the thermal medium from the generator to the accumulator. The plant further includes an auxiliary module provided on the first path, and a bypass path to convey the thermal medium flowing through the second path to the auxiliary module by bypassing the accumulator, wherein the auxiliary module is supplied with a first thermal medium from the accumulator via the first path, supplied with a second thermal medium from the second path via the bypass path, and supplies a third thermal medium to the generator via the first path.

摘要： A gas turbine plant including a gas turbine and a compressor is provided with a steam turbine plant including a steam turbine and a condenser, and, an exhaust heat recovery boiler. Steam from the exhaust heat recovery boiler is directly flown to the condenser of the steam turbine plant through a bypass control valve. A pressure sensor detects pressure in a turbine bypass system. A controller outputs, based on a set value from an input device and a process value from the pressure sensor, an open level instruction value to the control value so as to make the process value consistent with the set value in a predetermined sampling cycle. A corrector corrects the set value from the input device in a direction in which the open level instruction value decreases when the open level instruction value from the controller becomes a value that substantially fully opens the control valve.

摘要翻译： 包括燃气轮机和压缩机的燃气轮机设备设置有包括蒸汽轮机和冷凝器的蒸汽轮机设备和废热回收锅炉。 来自废热回收锅炉的蒸汽通过旁通控制阀直接流到蒸汽轮机厂的冷凝器。 压力传感器检测涡轮旁路系统中的压力。 控制器基于来自输入装置的设定值和来自压力传感器的过程值，将开放水平指令值输出到控制值，以使处理值在预定采样周期内与设定值一致。 当来自控制器的开启电平指令值变为基本上完全打开控制阀的值时，校正器在开启电平指令值减小的方向上校正来自输入装置的设定值。
