Beschreibung
Zusammenfassung:	The invention relates to a heat supply network circulating water pump steam turbine system of a high-back-pressure heat supply unit and a driving method, the system comprises an injection type heat pump, an injection steam inlet end of the injection type heat pump is connected with a main steam pipeline of a high-back-pressure steam turbine, and another steam exhaust pipeline is led out of the high-back-pressure steam turbine to be connected to an injected steam inlet end of the injection type heat pump. A steam exhaust end of the jet heat pump and a path of regenerative steam extraction pipeline led out of the high-back-pressure steam turbine are connected to a steam inlet end of a heat supply network circulating water pump steam turbine, and a steam exhaust end of the heat supply network circulating water pump steam turbine and a path of steam exhaust pipeline led out of the high-back-pressure steam turbine are both connected to a steam inlet side of a heat supply network heater; and a water outlet of the h
