Abstract


Gas-steam combined cycle power plant with natural gas pipe network affect each other mutual restraint , both coupling characteristics important for guiding the coordinated operation of the combined cycle power plant and natural gas pipeline network . This paper analyzes and calculates the combined cycle unit load range corresponding to the supply capacity of the natural gas pipeline network , gas-fired power station fuel consumption model and the introduction of natural gas pipe network model to analyze the impact properties of the gas-fired power plants run on natural gas pipeline network . Gas scheduling based on gas-fired power station run plans to use a constant flow air supply gas supply in advance , can be drawn through the thesis combined cycle cogeneration units can meet the heating load requirements regulating the consumption of natural gas ; effectively reduce the gas-fired power stations liter pressure shock load caused by operation of the pipeline network .
