摘要:
The invention relates to a pitch drive device (10) capable of emergency operation for adjusting a rotor blade pitch of a wind or water power plant. The pitch drive device (10) comprises an inverter device (14) and a three-phase current drive motor. The drive motor is implemented as a three-phase IPM synchronous motor (12) (Interior Permanent Magnet). A direct current power storage device (20) can advantageously be substantially directly connected to an intermediate direct current circuit (18), at least for emergency operation, between a rectifier device (16) and the inverter device (14) for at least briefly supplying power to the synchronous motor (12), so that the IPM synchronous motor (12) can be operated at least briefly under speed control when the intermediate circuit voltage UZK is falling. The invention enables speed-controlled emergency operation of the pitch drive device at high torque when an intermediate circuit voltage UZK is falling in emergency operation, wherein the direct current energy storage device can, for example, improve the efficiency as an energy buffer, and reduce current transfer via the rotor slip ring.
摘要(中):
本发明涉及一种notbetriebsfähige桨距驱动装置(10),用于调节风力或水力涡轮机的转子叶片桨距。 桨距驱动装置(10)包括逆变器装置(14)和三相驱动马达。 所述Anthebsmotor被提供为三相IPM同步电动机(内置式永磁),其适于(12)。 有利的是,一个DC能量存储装置(20)可以基本上直接连接到整流器装置之间的直流电压中间电路(18),(16)和所述逆变器装置(14),用于至少在至少用于紧急操作的同步电动机(12)的短期功率,从而使 该IPM同步电动机(12)可以在受控的下沉中间电路电压UDC的速度至少暂时被操作。 本发明使桨距驱动装置的速度控制的紧急操作的下沉在应急操作与高转矩中间电路电压UDC,例如,将DC电力存储装置,以提高能量缓冲器的效率,并且可以减少通过转子滑环的动力传递。
