Abstract

The invention discloses a high-pressure control valve flow optimization device for a turbine unit. The high-pressure control valve flow optimization device comprises an instruction control module used for sending out aperture signals of various control valves, an executing module used for receiving instructions and controlling the aperture changes of the control valves, a data collecting module used for collecting turbine adjusting-stage pressure, turbine main vapor pressure and other real-time parameters, and a data simulating optimization module used for conducting data simulation and optimization on a flow characteristic curve according to the aperture of the control valves and the turbine parameters collected by the data collecting module. The invention further discloses a high-pressure control valve flow optimization method for the turbine unit. The defects in the prior art can be overcome, the load disturbance phenomenon in the switching process is eliminated, and accordingly it is guaranteed that the unit valves safely, stably and economically run in the switching state.

Description

technical field [0001] The invention relates to the technical field of power generation steam turbine sets, in particular to a steam turbine set high-pressure valve flow optimization device and an optimization method thereof. Background technique [0002] At present, with the rapid development of electric power construction, the structure of the power grid is becoming more and more complex. In order to ensure the safe and stable operation of the power grid, the generator set must have the ability to quickly respond to changes in the automatic generation control command (AGC, Automatic Generation Control) of the power grid and the regulation of primary frequency regulation. The realization method is mainly to control the action of high-pressure adjustment of the steam turbine, quickly adjust the steam intake of the steam turbine, and then realize the rapid response of the unit load. It can be seen that the quality of the digital electro-hydraulic control system (DEH, Digital ...
