Abstract
Methods, apparatuses, and systems for real-time monitoring and automated intervention of a power generation. Embodiments may include receiving operating data from components of the power generation system. A potential failure condition for the components may be determined from real-time operating data of the received operating data before an occurrence of the potential failure condition. An alert may be issued in response to determining the real-time operating data indicates a potential failure condition, and instructions for remedying the potential failure condition may be transmitted to the power generation system. An algorithm for determining whether the real-time operating data indicates the potential failure condition may be updated by using preceding operating data in response to detecting the potential failure condition.
