The utility model discloses a water and electricity cogeneration system, this water and electricity cogeneration system includes: steam supply device, main steam turbine (2) be connected with the steam supply device and through main steam turbine driven generator (16), water and electricity cogeneration system still includes: driving steam turbine (4), this driving steam turbine passes through main steam turbine's the drive of drawing gas, water -feeding pump (12), this water -feeding pump passes through the driving steam turbine drive is in order to supply water to the steam supply device, and seawater desalination unit (10), the heating steam entry of this seawater desalination unit and the steam drain intercommunication of driving steam turbine. Above -mentioned water and electricity cogeneration system utilizes the steam extraction of drive turbine as the heating steam of seawater desalination unit, realizes the reutilization of the steam extraction of driving steam turbine, avoids the energy waste that causes the direct condensation of high temperature steam extraction to, drive steam turbine steam exhaust volume is less, avoids the problem of the main steam turbine's that can't dissolve of seawater desalination unit the unable normal operating of the generating set that a large amount of steam extraction caused.
