Power system and energy management strategy for hydrogen fuel hybrid power shunting locomotive
The paper investigated and designed a hybrid power source system
with hydrogen fuel cells as the primary source and lithium batteries as the auxiliary power source
for locomotives used in station operations
addressing issues of slow dynamic response
soft output characteristics
and inability to recover braking energy associated with fuel cell technology. Using hybrid driving as the baseline
traction calculations were first carried out based on locomotive parameters and actual operating conditions
and a power source system topology was designed by considering the output characteristics of both the hydrogen fuel cells and power batteries. Then
energy management strategies based on different operating conditions and various states of charge for power batteries were proposed to jointly schedule the output modes and characteristics of the two power sources. A power source system configuration was designed and implemented by calculating the operating conditions and system topology. Finally
through practical applications in various on-site working conditions
it is proved that the hybrid power source system designed in this paper can effectively meet the traction requirements of locomotives
and the designed energy management strategy can achieve efficiency improvement
verifying the correctness of the theoretical analysis.
