摘要： A wind powered turbine with low voltage ride-through capability. An inverter is connected to the output of a turbine generator. The generator output is conditioned by the inverter resulting in an output voltage and current at a frequency and phase angle appropriate for transmission to a three-phase utility grid. A frequency and phase angle sensor is connected to the utility grid operative during a fault on the grid. A control system is connected to the sensor and to the inverter. The control system output is a current command signal enabling the inverter to put out a current waveform, which is of the same phase and frequency as detected by the sensor. The control system synthesizes current waveform templates for all three-phases based on a sensed voltage on one phase and transmits currents to all three-phases of the electrical system based on the synthesized current waveforms.

摘要： A power generating system wherein a turbine is mounted on top of a tower or tethered underwater. The turbine includes a rotor having a main blade connected to a rotor hub and an extender section. An adjusting device positions the extender blade between a retracted position within the main blade and to an extended position to expose more or less of the rotor to the fluid flow. The adjusting device includes a servo-controlled rack and pinion mechanism that converts rotation of the pinion by a servomotor into linear motion of the extender blade. A generator is connected to the turbine for generating electrical energy.

摘要： A tall tower is divided into an upper section with a tower top and a lower section with a tower bottom. The sections are hinged together. The lower section is hinged to a tower base. A telescoping crane is attached to a lift point on the lower section. The crane is extended to lift the sections to the vertical position with the lower section resting on the base and the tower top of the upper section near ground level. A heavy load is attached to the tower top end using a small ground crane while the tower top of the upper section is near ground level. The telescoping crane is attached to another lift point on the upper section to partially lift the upper section, which is supported in this position. The telescoping crane is relocated and reattached to the lift point on the upper section. The telescoping crane is fully extended to raise the upper section and load to vertical above the lower section.
