Popis
Shrnutí:Energy storage battery pack is the core component of the seismic station energy supply, to ensure the seismic station green economy, safe and stable operation, improve the lithium battery charge state accurate estimation, is proposed based on adaptive particle swarm improved estimate battery State-of-Charge extension Kalman filter algorithm, through the forgetting factor recurrence multiplication online identification battery model parameters based on the SOC estimate, the Adaptive Mixovariation Particle Swarm Optimization algorithm optimization Extended Kalman Filter algorithm noise variance matrix, and the system and the measurement noise matrix optimization, further improve the estimation accuracy of SOC. The results show that the AMPSO-EKF algorithm can accurately identify the battery model parameters and the SOC values, and can correct the initial error of the state variable well.
