The invention relates to a method and a device for determining an association relationship between a power quality event and an event cause, computer equipment and a storage medium, and belongs to thetechnical field of power grids. The method comprises the steps of: acquiring a plurality of power quality events, and integrating the power quality events corresponding to the same disturbance sourceinto a disturbance event; determining a matching relationship between the disturbance event and a preset event cause; discretizing the disturbance event to extract an event feature therefrom; and determining an association relationship between the event feature and the event cause according to the matching relationship. The above technical solution solves the problem that the association relationship between the power quality event and the cause is not accurately determined, and can accurately determine the association relationship between the power quality event and the event cause.
Description
technical field [0001] The present invention relates to the field of power grid technology, and in particular, to a method, device, computer equipment and storage medium for determining the correlation between power quality events and event causes. Background technique [0002] The power quality monitoring system (PQMS) has basically realized the recording and analysis of transient and steady-state data in substations with voltage levels of 110kV and above in urban power grids. At present, the in-depth application of power quality monitoring data mostly focuses on disturbance type identification, fault source location, on-line load monitoring, and comprehensive power quality assessment. In addition, in the process of implementing the present invention, the inventor also found that there are at least the following problems in the prior art: the correlation relationship between the power quality event and the cause determined by the traditional method is not accurate enough. ...
