Malignant load identification method, device and equipment, and storage medium

Abstract

The embodiment of the invention discloses a malignant load identification method. The method comprises the following steps: acquiring power utilization parameters of power utilization equipment at a plurality of moments; determining reactive power at each moment based on the power utilization parameters at each moment; and outputting a malignant load identification signal when the change of the reactive power at the plurality of moments does not meet a first change condition, wherein the malignant load identification signal is used for representing that the electric equipment is a malignant load. The embodiment of the invention also discloses a malignant load identification device, malignant load identification equipment and a storage medium.

Description

technical field [0001] The present application relates to the technical field of load identification, and in particular to a malicious load identification method, a malicious load identification device, a malicious load identification device, and a storage medium. Background technique [0002] At present, with the popularity and increase of electrical equipment, while bringing convenience to people's lives, it also brings safety hazards due to the use of some vicious loads. Among them, the vicious load includes a high-power resistive load. [0003] Traditional methods for identifying malignant loads include the total power threshold method, power factor method, instantaneous power method, and area relationship judgment method, but the above methods all judge malignant loads based on the instantaneous value at a certain moment. However, the misjudgment rate of judging the malignant load based on the instantaneous value is high, and the malignant load cannot be accurately ide...
