  • Patent number: 9912209
    Abstract: Three controls, three variable gear assemblies, a hatch, and a variable torque and power generator (VT&PG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed. A three variable spur/helical gear assembly of sun and planetary gear sets is a mechanical three variable control and referred to herein as a Transgear™ gear assembly, simply Transgear. A hatch wraps around a waterwheel and may control the amount of water inlet to the system by opening and closing and may be controlled by Transgears and a VT&PG. Two Transgears may comprise a constant speed motor control and produce required frequency and voltage and be reduced in part count and complexity.

  • Patent number: 9906177
    Abstract: A low-frequency band suppression enhanced anti-reversal power system stabilizer is presented by the invention. Currently the widely used PSS2B power system stabilizer needs lead elements above Order 2 to meet the phase compensation requirement of DC blocking signal of active power, thus quickly increasing high-frequency band gain, restricting allowable total setting gain of PSS, limiting low-band gain and reducing low-frequency band suppression ability of power system stabilizer. The invention will add generator speed signal ? (which is treated by DC blocking element and corrected by parallel proportional differential PD) and active power signal Pe (which is treated by DC blocking element and gained by gain factor Ks3) to get equivalent synthetic mechanical power of power system stabilizer.

  • Patent number: 9890761
    Abstract: A hydro-electric power system includes two containers and a support beam having two ends, each end holding one of the containers. The ends allow the containers to travel along a length of the support beam. The support beam pivots about a pivot point, giving each container a maximum height and a minimum height. Fluid flows into each of the containers when located near their maximum height, the flow of water weighting each container and causing it to descend, each container moving longitudinally outward from the pivot point along the support beam as it descends. A dumping mechanism causes each container to release fluid near its minimum height, each container ascending after releasing water and moving longitudinally inward toward the pivot point along the support beam.
