Title: Improvements in or relating to torque governors for a windmill
IPC: F03D7/02
Filed: 1950-12-12
Abstract: 696,653. Variabte - speed differential gear. ROMANI, L. Dec. 12, 1950 [Dec. 16, 1949], No. 30353/50. Class 80 (ii). [Also in Group XXVI] A synchronous alternator 6, or a generator connected to a buffer battery, is driven at constant torque by a windmill 1, subject to wide fluctuation, differentially with a variable power absorber such as a compressor or one or two fans 9, 9<SP>1</SP>, operating in the same medium, air, as the windmill, and adjusted to maintain constant torque on the alternator, which latter rotates at constant synchronous speed to supply a distribution network with its full rated power when wind speed is sufficient. The fan torque is controlled by wind-speed responsive electrically-operated pitch-variation and in some forms the fan may, at low wind-speeds, supply deficient power, as well as absorbing surplus at higher speeds. In Fig. 1 the main windmill 1 drives through fixed step-up ratio planetary or other gear 3, an input shaft 4 passing freely through the alternator-shaft 12 and carrying the planets of a differential torque-balancing gear, one output member, the ring-gear 7, of which is fast to the alternator-shaft 12, whilst the other, tho sun 13, drives in opposite directions two transverse fans 9, 9<SP>1</SP>. Below a predetermined wind-speed (16 metres / sec.) the fans 9 are automatically locked to maintain alternator output. Between this and a higher speed (25 m/s) the fans 9 absorb power variably under wind-speed responsive pitch-control, permitting the windmill to overrun the synchronous speed. Above this wind-speed the windmill must be shut down and, for this purpose, the fans 9 are used as auxiliary motors, either by changing the pitch or direction of rotation of either one only so that they turn the assembly until the main windmill 1 is in the lee of the wind, permitting it to be braked to rest at 5. The alternator remains always connected to the network and acts as synchronous capacitor when not generating. In Fig. 2 (not shown), the shafts of the main windmill and of a single fan are parallel and a clutch-brake is provided between the alternator and its differentially driven element, in this case a sun, as well as a brake for the input planetcarrier. When the alternator is declutched and its sun braked, the fan and main windmill are set in opposition so that only light braking of the input carrier is required to stop both. With this arrangement the fan also supplies deficient power at low wind-speeds. In Fig. 3 (not shown), the shafts of the windmill and single fan are coaxial and the differential balancing gear has double sun-ring trains, with two braked ring-gears, the brakes of which replace the clutch-brake of Fig. 2.
