Abstract: This disclosure is directed to a method for operating a wind turbine which includes a speed-variable drive system. The system includes an electrical machine and a pulsewidth modulation-controlled converter. The speed-variable drive system is connected to an electrical grid. In the event of a transient grid fault, a frequency of the pulsewidth modulation is determined in response to a current in an electrical circuit connected to the converter.

Abstract: The electric power generating device includes a first generator, a differential gear mechanism provided between a blade and the first generator, a first ring gear connected to the first generator, and a case that rotates integrally with the first ring gear about a first axis. The differential gear mechanism includes a pinion shaft that rotatably supports a pair of pinion gears about a second axis perpendicular to the first axis. The differential gear mechanism includes a first drive shaft having a first side gear at one end and a blade connected to the other end. The differential gear mechanism comprises a second drive shaft having a second side gear at one end and having an interference portion at one end extending toward the pinion shaft. The interference portion faces the pinion shaft in a direction of a third axis that is orthogonal to the first axis and the second axis.

Abstract: A rotary machine for a power system includes a rotary drum having a rotational center shaft, a stationary half gear including a generally circular non-geared portion and a geared portion having gear teeth, and at least one pair of revolving gears formed of two revolving gears symmetrically positioned about the center shaft and configured to simultaneously revolve around the stationary half gear. At least one rack shaft is operably coupled, directly or indirectly, to the revolving gears to reciprocate back and forth upon rotation of the revolving gears, and as the revolving gears revolve around the stationary half gear, one of the two revolving gears is configured to have gear engagement with the geared portion of the stationary half gear, while the other revolving gear is floating over the non-geared portion of the stationary half gear.
