Abstract

The invention discloses a steam supplying system for dynamic performance testing of a turbogenerator unit. The steam supplying system comprises a boiler and further comprises a main steam valve, the turbogenerator set, a double-pressure condenser and a pump unit; the boiler is sequentially and circularly connected with the main steam valve, the turbogenerator set, a steam inlet in the low-pressureside of the double-pressure condenser and the pump unit, and thus a closed-loop working loop is constituted; a branch circuit is connected to a pipeline between the boiler and the main steam valve and sequentially provided with a pressure reducing valve, a restriction orifice and a desuperheater; the tail end of the branch circuit is connected with a steam inlet in the high-pressure side of the double-pressure condenser; and an outlet in the high-pressure side of the double-pressure condenser is connected with the pump unit. During dynamic performance testing of the turbogenerator unit, the pressure reducing valve is automatically opened or the opening degree of the pressure reducing valve is automatically reduced according to the deviation of steam pressure in front of the main steam valve and the set value and the change rate of the steam pressure, and thus the steam pressure in front of the main steam valve is maintained in the requirement range.

Description

technical field [0001] The invention relates to the technical field of steam turbine generator sets, in particular to a steam supply system used for dynamic performance testing of steam turbine generator sets. Background technique [0002] During the performance test of the steam turbine generator set, a single boiler supplies steam to the steam turbine generator set, which is a unit heating system, that is, one boiler corresponds to the operation mode of one or more steam turbine generator sets. The steam in the room cannot be stored, and the test requires cooperation and coordination between the boiler and the turbo-generator set, otherwise it will cause fluctuations in the steam supply pressure and the operating speed of the turbo-generator set, which cannot meet the test and test requirements. [0003] During the dynamic performance test of the turbo-generator set, the maximum load change of the turbo-generator set suddenly changes between 100% and 0%, and the inlet stea...
