Abstract: A method for transitioning a wind turbine into an energy harvesting mode in which the wind turbine generates electrical power from wind energy is provided. An energy storage system supplies electrical power to an auxiliary system when the wind turbine is not generating or receiving electrical power sufficient for supplying the auxiliary system. The method includes operating the wind turbine in a first operating mode in which an electrical power supply is ceased; obtaining environmental data including at least one of wind data and meteorological data; and determining if the obtained environmental data meets a predefined condition. If the predefined condition is met, a transition of the operation of the wind turbine into the energy harvesting mode is caused, wherein transitioning the operation into the energy harvesting mode comprises supplying electrical power from the energy storage system to the one or more auxiliary power consumers of the first group.

Abstract: A rotation speed avoidance control method for a wind turbine generator system. The method comprises: when a power-limited operation instruction is received, determining a power value upper limit required by the instruction: determining whether the required power value upper limit is in a power avoidance interval corresponding to a rotation speed avoidance interval; and when the required power value upper limit is in the power avoidance interval, setting the maximum allowable power value of a wind turbine generator system to be a lower boundary value of the power avoidance interval. An upper boundary value of the power avoidance interval is a power value determined on the basis of an upper boundary value of the rotation speed avoidance interval, and the lower boundary value of the power avoidance interval is a power value determined on the basis of a lower boundary value of the rotation speed avoidance interval, wherein the rotation speed avoidance interval and the power avoidance interval are open intervals. By means of the control method, an operation range of the rotation speed of a wind turbine generator system in a power-limited operation state can be prevented from overlapping with a rotation speed avoidance interval, thereby preventing resonance of the generator system, load increase or other safety problems. In addition, the present invention further relates to an apparatus for implementing the control method, and a wind turbine generator system.

Abstract: ProblemTo maintain high fuel consumption performance also in the charging by a drive of an alternator at the non-deceleration in a power source management system that drives the alternator during vehicle deceleration to charge a battery.SolutionA power generation cost of an alternator is found from a rotational speed and torque of an engine at the non-deceleration The alternator is driven only when an SOC of a battery is in a drive permission zone Z in which, based upon the power generation cost, the SOC and the power consumption, the SOC is the lower as the power generation cost is the higher and the SOC is the higher as the power consumption is the higher. The fuel consumption performance is higher as compared to a conventional example of always driving the alternator when the SOC is equal to or less than a maximum upper limit value SOCm regardless of the power generation cost as an index of an engine efficiency.

Abstract: A method for operating a turbine having a rotor including a hub and at least one blade rotatably arranged around its longitudinal axis at the hub, an induction generator having a stator and rotor coupled to the turbine shaft, a pitch drive system having an actuator, a control system, and a measuring device. The method includes: measuring the operational value of a component of the pitch drive system and adjusting the angle to the target pitch angle, wherein the wind turbine is operated according to at least two operational modes. During a first mode, a first target pitch angle is determined at least according to a power curve of the wind turbine or measured wind speed. During a second mode, a second target pitch angle is determined by adding a pitch offset to the first target pitch and is activated when the measured operational value exceeds a predefined activation threshold.
