The invention discloses a steam turbine unit system and a control method thereof. The steam turbine unit system comprises an operation unit and an outage unit; the operation unit comprises a first operation unit; the first operation unit comprises an operation unit condensate system and an operation unit condensate user; the operation unit condensate system comprises an operation unit condensate pump; the operation unit condensate pump is connected to the operation unit condensate user through a first pipeline to deliver condensate of the operation unit condensate system to the operation unitcondensate user; the operation unit condensate pump is connected to an outage unit condensate user through a third pipeline to convey the condensate of the operation unit condensate system to the outage unit condensate user; and a second valve is arranged on the third pipeline. The steam turbine unit system adopting the scheme can solve the problem that when the current steam turbine unit is in operation, a large amount of energy is wasted, and when the steam turbine unit is out of service, a condensate pump needs to be operated for a long time to cause higher power consumption.
Description
technical field [0001] The invention relates to the technical field of a steam turbine set, in particular to a steam turbine set system and a control method thereof. Background technique [0002] The steam turbine unit includes a condensate water system. The condensate water system needs to provide water to the relevant condensate water users through the condensate water pump. For example, the condensate water can be used as desuperheating water for the shaft seal system of the steam turbine unit, cooling water for the shaft plus fan, and expander for the exhaust device. cooling water, etc. After the steam turbine unit is out of service, the boiler of the condensate user still has high-temperature and high-pressure steam. In order to avoid deformation of the boiler under the action of steam, it is necessary to perform maintenance on the boiler with pressure and vacuum pumping, but the maintenance process takes at least 50 hours, so the condensation The water pump has to run...
