The invention relates to the technical field of intelligent monitoring, in particular to an intelligent diagnosis
system and method for a comprehensive energy
station, and the
system comprises a dynamic trajectory capture module, a
lag response analysis module, a mismatch behavior diagnosis module and a fault chain positioning module. According to the method, a
dynamic time warping algorithm is adopted to process sliding window
time sequence data and calculate track slope difference, capture precision of instantaneous disturbance characteristics is enhanced, a
grey correlation model is utilized to analyze track matching degree and set a dynamic
lag threshold value, and a continuous non-convergence condition trigger mechanism is combined to improve hidden fault identification sensitivity. Multi-parameter range calculation and direction consistency check integrate start-stop frequency and load
rate change trend, reduce misjudgment risk caused by
single parameter fluctuation, construct a
time sequence alignment axis and calculate
delay response joint probability distribution, realize time-space association of historical data and real-time monitoring, accurately locate a
coupling relationship of a multi-source fault chain, and improve the reliability of the multi-source fault chain. The abnormal state early warning capability is enhanced, and the fault positioning efficiency is optimized.
