The present invention discloses an electrical appliance operating state recognition method based on a dual-sliding window. The method comprises the steps of inputing a user electricity consumption overall load, identifying a steady-state load, detecting steady-state load change, correcting the steady-state load, identifying an electrical appliance operating state, and outputing electrical appliance operating operation sequence. According to the method, in the condition of known user total power consumption and electrical appliance power consumption information, the use condition information of a user electrical appliance is analyzed, the method has an important reference value for the power system data publication and has an important reference meaning for understanding the use condition of the electrical appliance and rationally using electrical energy by the user.
