Abstract

The invention provides a method for adjusting the frequency of a power grid. According to the technical scheme, a frequency modulator is manually or automatically operated; and the frequency characteristics of a generator set move up and down in parallel, so that a frequency offset caused by load change can be kept within an allowable range. The method has the beneficial effects of being reasonable, practical, time-saving and labor-saving; the work efficiency is improved; and the operation quality of the power grid is improved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a method for adjusting the frequency of a grid. Background technique [0002] At present, the grid power supply does not adjust the frequency of the grid system, and the frequency quality cannot be guaranteed, which reduces the total generator unit regulation power in the system. Contents of the invention [0003] The purpose of the present invention is to provide a method for grid frequency adjustment. The technical solution is: manually or automatically operate the frequency regulator, so that the frequency characteristic of the generating set moves up and down in parallel, so that the frequency deviation caused by the load change can be kept within the allowable range. [0004] The beneficial effect of the present invention is that it is reasonable and practical, saves time and labor, improves work efficiency, and improves the operation quality of the power grid. det...
