The invention relates to a heat power cogeneration machine set deep peak adjusting bypass heat supplying running device and running method. The heat power cogeneration machine set deep peak adjustingbypass heat supplying running device comprises a complete system which is composed of a steam turbine high-pressure cylinder, a steam turbine intermediate-pressure cylinder, a steam turbine low-pressure cylinder, a high-pressure bypass adjusting valve, a low-pressure bypass adjusting valve, a high-pressure cylinder exhaust auxiliary ventilation adjusting valve, a low-pressure bypass shut-off valveand various other adjusting valves. According to the heat power cogeneration machine set deep peak adjusting bypass heat supplying running device and running method, by means of automatic or manual adjustment, the interconversion process of power and heat in a system is achieved, the purpose of deep peak adjusting is achieved, the heat power cogeneration machine set deep peak adjusting bypass heat supplying running device and running method have the beneficial effects that the interconversion flexibility of load of power and heat is improved, the capacity of deep peak adjusting is achieved, under the situation that the cold source loss of a machine set is unchanged, the lowest power load can reach 17% or below of the rated capacity through adjustment, and the heat power cogeneration machine set deep peak adjusting bypass heat supplying running device and running method are flexible, large in peak adjusting amplitude and economic and reliable.
Description
Technical field: [0001] The invention belongs to the technical field of heat supply and energy saving of heat and power cogeneration units in electric power systems, and in particular relates to a heat supply operation device and an operation method for deep peak-shaving bypass heating of a heat and power cogeneration unit. Background technique: [0002] With the development of electric power, my country's installed capacity is getting bigger and bigger, and the power generation peak-valley difference required by the power grid is also getting bigger and bigger. When thermal power plant cogeneration units supply heat in winter, with the increase in energy saving, the heating unit After the energy-saving transformation, the heat consumption is getting lower and lower, but the peak-shaving capability of the unit is getting lower and lower, and the heating condition of the unit operation is in conflict with the electrical load required by the grid. Mainly manifested in the follo...
