Abstract

The invention discloses a steam turbine primary frequency regulation method and device, storage medium and processor. Wherein, the method includes: obtaining the power fixed value of the power grid; adding the power fixed value as a feed-forward parameter into the comprehensive valve position instruction; The invention solves the technical problem that the adjustment quality of the primary frequency modulation method in the related art is poor.

Description

technical field [0001] The invention relates to the field of frequency modulation, in particular to a steam turbine primary frequency modulation method and device, storage medium and processor. Background technique [0002] The primary frequency regulation action process of the steam turbine in the power plant is as follows: After the generator is connected to the grid, when the power demand of the grid changes, the outlet current of all generators in the grid will change, which will change the electromagnetic resistance on the rotors of all generators in the grid , when the steam intake of the steam turbine remains unchanged, the change of electromagnetic resistance will cause the speed of all generators in the grid to change, and the change of the speed of all generators will cause the frequency of the entire grid to change. In order to ensure the grid frequency, all grid-connected units must pass The control system opens or closes the steam inlet valve of the steam turbin...
