A hydraulic system of a hybrid power rotary drilling rig comprises an engine, an electric generator, a motor set, a main pump, an auxiliary pump, a main hydraulic system, an auxiliary hydraulic system, a main winch, a power head and a control assembly. The motor set comprises a main pump motor, an auxiliary pump motor, a main winch motor, a first power head motor and a second power head motor which are electrically connected with the generator; the main pump motor drives the main pump, the auxiliary pump motor drives the auxiliary pump, the main winch motor drives the main winch, and the first power head motor and the second power head motor drive the power head. The main pump is connected to the main hydraulic system, and the auxiliary pump is connected to the auxiliary hydraulic system. The motor set, the main hydraulic system and the auxiliary hydraulic system are all in signal connection with the control assembly. The control assembly is used for sending control signals to the motor set, and the main hydraulic system and the auxiliary hydraulic system are used for enabling execution elements in the rotary drilling rig to execute corresponding actions. The invention further relates to a control method of the hydraulic system of the hybrid power rotary drilling rig and the hybrid power rotary drilling rig.
