The application discloses a kind of
hybrid power
system health management method and
system, belong to power
system health management field.This application selects the characteristic
signal of engine, battery and vehicle in
hybrid power system to establish
hybrid power system health degree;When
hybrid power system fails, by obtaining characteristic
signal and carrying out normalization
processing,
hybrid power system health degree based on
grey correlation analysis method GRA is calculated in real time, and the misjudgment and the missed judgment of fault are reduced by the fault confirmation method based on counting;When
hybrid power system fault is confirmed, through the power redistribution health
management strategy under system fault based on LSTM-MPC, the change of hybrid power system speed, battery temperature and
diesel engine exhaust temperature in limited
time domain is predicted, and the
predictive maintenance of hybrid power system health degree is carried out in combination with the
change prediction result of part of the state of hybrid power system, so that hybrid power system can still operate with fault under the condition of meeting constraint.
