Hydroelectric power plant real-time monitoring system and method

摘要

A hydroelectric power plant real-time monitoring system comprising a real-time data acquisition system (11) connected to dedicated sensors positioned in a hydroelectric power plant (2) and configured to acquire in real-time measured power plant data comprising simulation inputs (111), and at least one real-time measured monitored quantity (112). The monitoring system also comprises a real-time simulation system (12) and a real-time diagnostic system (13), whereby the simulation system is configured to receive the measured simulation inputs (111), to simulate in real-time a transient behavior of the hydroelectric power plant based on the measured simulation inputs and to provide in real-time simulated power plant data related to the transient behavior of the power plant and comprising at least one first real-time simulated monitored quantity (122) corresponding to a simulated quantity of the measured monitored quantity (112). The real-time diagnostic system (13) compares the measured monitored quantity with the first simulated monitored quantity (122) to trigger, in case of deviation above a first threshold, a first alarm identifying a first power plant transient behavior problem and/or to compute at least one first output related to the measured quantity (112) and at least one second output related to the first real-time simulated quantity (122) and compare the first output with the second output to trigger, in case of deviation above a second threshold, a first alarm identifying a first power plant transient behavior problem.
