A hybrid power locomotive and an energy balance control method and system thereof. A rotating speed of a power pack is calculated according to a power needing to be developed by the power pack, and the power pack is made to operate at the rotating speed, so that the power of the power pack is fully developed, and the efficiency under the power is improved. When the actual output voltage of the power pack is higher than a target voltage value, redundant energy is stored in an energy storage element, energy waste is avoided while the power of the power pack is guaranteed to be fully developed; and when the actual output voltage of the power pack is lower than the target voltage value, the energy storage element releases energy to provide energy for a load, and overload of the power pack is avoided. According to the control method, the energy utilization rate is maximized by means of self-adaptive matching of the rotating speed and the power, dynamic balance control over the actual output voltage of the power pack is achieved by means of charging and discharging control over the energy storage element, and energy waste and power pack overload are avoided.
