Fixed-frequency air conditioner starting identification method and device and storage medium

The invention discloses a fixed-frequency air conditioner starting identification method and device and a storage medium. The fixed-frequency air conditioner starting identification method comprises the steps: collecting the voltage and current of a preset monitoring point in a monitoring environment according to a preset sampling frequency and generating an active power time sequence; acquiring apulse point at the moment of fixed-frequency air conditioner starting according to the active power time sequence; acquiring a plurality of power intervals by taking the pulse point as a base point in the active power time sequence, and respectively carrying out statistics on the fluctuation frequency corresponding to each power interval; and judging whether the fixed-frequency air conditioner inthe monitoring environment is started or not according to the fluctuation frequency corresponding to each power interval. Under the condition that a single electric appliance operates and multiple electric appliances operate
