A power system comprises: a motor; a flow valve; and a bypass valve; a generator configured to convert mechanical power from the motor to electrical current; a sensor configured to measure an operating frequency of the electrical current, and generate a sensor signal comprising a measured operating frequency; and control circuitry configured to: when the generator is in an operating mode, output a first control signal to control the flow valve to enable the flow of the hydraulic fluid to the motor and output a second control signal to control a degree of openness of the bypass valve based on the sensor signal, and when the generator is in an off mode, output the first control signal to control the flow valve to disable the flow of the hydraulic fluid to the motor.
