In a turbine engine hydrogen is injected into the combustor in response to a power output level of the turbine engine. In a preferred embodiment, gaseous hydrogen is always injected at low-power operations and switched off at mid-power and high-power operations.

The invention discloses an energy control method of a hydrogen fuel cell and power cell hybrid power bus. The method comprises the following steps of: collecting motor power data, selecting SOC valueswithin a certain range around the average power value of the motor, and conducting interpolation distribution on the power range of a galvanic pile, increasing vehicle parking judgment, locking the variable-load frequency standard of the galvanic pile, and evaluating whether the variable-load frequency standard meets requirements or not, judging the SOH condition of the battery, and increasing the low SOC to forcibly start the reactor. Based on the galvanic pile system controller, the BMS and the whole vehicle controller system, energy control strategy assignment and optimization can be completed through real-time data. And the VCU is used for judging the power state of the whole vehicle, so that the low-power power supply and low-SOC forced starting operation of the parking galvanic pileare increased, and the healthy working states of the galvanic pile and the battery are further ensured. Therefore, the galvanic pile outputs as low as possible on the basis of meeting the power requirement of the whole vehicle as much as possible, and hydrogen consumption is reduced while the service life of the galvanic pile is ensured. And meanwhile, the battery can work in a relatively high and stable SOC interval, and the service life of the battery is prolonged.
