The invention discloses a turboset and a control method. The turboset comprises a main steam turbine system, a waste heat steam turbine system, a steam pump system and a heat supply system; a steam extraction outlet of a medium pressure cylinder of the main steam turbine system is connected with the heat supply system; and an acting dead steam outlet of the medium pressure cylinder of the main steam turbine system is connected with the heat supply system, the steam pump system and the waste heat steam turbine system. By the adoption of the turboset and the control method provided by the invention, acting dead steam utilization forms are diversified through the waste heat steam turbine system, the steam pump system and the like, the waste heat steam turbine system, the steam pump system andthe like are turned off in the copious cooling period, dead steam is completely used for heat supply, on the one hand, deep peak regulation of the turboset is facilitated, and on the other hand, theheat supply amount is guaranteed in the deep peak regulation period.
Description
technical field [0001] The invention relates to the technical field of power generation, in particular to a steam turbine unit and a control method. Background technique [0002] In the case of extremely low ambient temperature in winter, there are many difficulties in the process of deep peak regulation of thermal power units (the peak regulation range is 30%-40% of the rated load), especially for heating units, there are more problems, such as low Under load, the amount of heating and extraction steam increases greatly, and the steam intake of the low-pressure cylinder of the steam turbine decreases. If it is not enough to take away the heat generated by the blowing loss, the temperature in the low-pressure cylinder will increase, and the elevations of the bearings of the shaft system will be inconsistent. The vibration of the system will increase abnormally; the deep peak shaving will operate at low load for a long time, the exhaust gas temperature is low, sulfur oxides w...
