Title:
SYSTEM FOR CONTROLLING PRESSURE AND POWER OF STEAM TURBINE OF THREE-BOILER TWO-TURBINE HEADER SYSTEM BIOMASS POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2023/226202
Kind Code:
A1
Abstract:
A system for controlling the pressure and power of a steam turbine of a three-boiler two-turbine header system biomass power plant, which system relates to the field of control over steam turbines of biomass power plants, and aims to enable a steam turbine set to stably operate at a set main steam pressure and a power plant to meet load control requirements of a power grid. The system in the present invention comprises: a main steam pressure control module, which is used for controlling a generator set to stably operate at a set main steam pressure; and an electric motor power control module, which is used for controlling an output power value of the generator set to remain at a set power value so that the generator set operates stably. The beneficial effects are: the pressure and power of two steam turbine generator sets are respectively adjusted, such that a boiler achieves stable combustion, and a power plant meets load control requirements of a power grid.
