Abstract

The invention discloses power generation equipment and a grid synchronization method thereof. Before a power generator of steam power generation equipment and a power supply network are synchronized, a cooling system serving as load is connected into the power generator, the temperature of steam at an outlet of a high pressure turbine can be further reduced, and therefore the influence on the outlet of the high pressure turbine and a cold branch of a middle superheating device by high temperature steam is reduced.

Description

technical field [0001] The invention relates to a power generation device, in particular to a steam power generation device and a grid synchronization method for the steam power generation device. Background technique [0002] Steam power plants typically include a steam turbine, condenser, pump and steam generator connected to a generator. A steam generator such as a boiler, heated by a heat source, transfers heat to a fluid passing through the steam generator. The heated fluid then powers a steam turbine, which drives a generator connected to the turbine to generate electricity. After leaving the turbine, the fluid flows through the condenser and then pumped back into the steam generator. [0003] In recent years, most of the steam turbine devices used in thermal power plants have adopted turbine bypass systems. The provision of a turbine bypass system to direct excess steam from the steam generator through the steam turbine. Even when the steam turbine is in the low l...
