The invention provides a hydropower production real-time information processing system and a hydropower production real-time information processing method based on mass data. The system comprises a hydropower production real-time information system, a mass historical/real-time data platform, and an acquisition terminal, wherein the acquisition terminal is connected with hydropower production generating equipment and the mass historical/real-time data platform for transmitting embodiment data of the received hydropower production generating equipment to the historical/real-time data platform. The mass historical/real-time data platform comprises a data storage module for storing the received real-time data. The hydropower production real-time information system is connected with the mass historical/real-time data platform through an UAPI interface. The hydropower production real-time information system comprises a state monitoring module, an event alarm module, a trend analysis module, a comprehensive searching module and a data statistical analysis module.
