Abstract

The invention discloses a power grid frequency filtering method, a user device, a storage medium and a device. The power grid frequency filtering method comprises the following steps of acquiring an initial power grid frequency of a target power grid; iterating the initial power grid frequency according to a preset random model equation; obtaining a characteristic value of the intermediate power grid frequency obtained by iteration; and when the characteristic value of the intermediate power grid frequency obtained by iteration satisfies a preset condition, taking the intermediate power grid frequency as a filtered target power grid frequency. The system noise is effectively removed through the power grid frequency after the iterative processing of the random model equation, so that the sampled power grid frequency is more accurate.

Description

technical field [0001] The invention relates to the technical field of signal filtering, in particular to a power grid frequency filtering method, user equipment, storage medium and device. Background technique [0002] Theoretically, the frequency of interconnected grids distributed in different regions is the same. Due to the influence of signal collection, transmission and other factors, the grid frequency signal has certain noise. [0003] In the process of power grid analysis and calculation, the grid frequency is an extremely important parameter. However, the current frequency signal is directly used for the primary frequency modulation control of thermal power units, and its accuracy is poor, which will easily lead to frequent fluctuations in the primary frequency regulation and affect the primary frequency regulation. effect, and may bring hidden dangers to the safety of power plant operating equipment, especially the anti-fuel system. [0004] The above content is ...
