The invention discloses a hybrid power supply system of a rail transit vehicle, a control method of the hybrid power supply system and the rail transit vehicle. The power supply system comprises a diesel generating set which is connected with an AD/DC converter; the AC/DC converter is connected with the traction inverter through a DC bus. The system is characterized in that a photovoltaic assemblyand an energy storage device are connected in parallel to a DC bus between the AC/DC converter and the traction inverter. The problem of energy matching of a diesel generating set, a photovoltaic power generation system and a lithium battery energy storage system under the operation condition is solved, fuel consumption, tail gas emission and noise are reduced, and the energy utilization rate isincreased.
