Method and device for supplementing real-time data of photovoltaic power station and related equipment

The invention discloses a photovoltaic power station real-time data supplementing method and device and related equipment, and the method comprises the steps: obtaining station data collected by a photovoltaic power station at a current observation point, and judging whether data missing exists or not; if yes, constructing feature data by using historical site data, and inputting the feature data into the trained model to obtain estimated data of the current observation point; performing data supplementation on the site data acquired at the current observation point by using the estimated data to obtain complete site data of the current observation point; the model is configured to have the capability of carrying out feature extraction on a time sequence and single-point data, and is obtained by taking feature data constructed by site data before a second observation point as input features and taking site data of a first observation point as annotation training. According to the method, the model combining t
