SCALABLE AND EFFICIENT MECHANICAL SPEED CONVERTER-CONTROLLED WIND AND HYDROKINETIC TURBINES

NºPublicación: WO2020139863A1 02/07/2020

Solicitante:

DIFFERENTIAL DYNAMICS CORP [US]
HAN KYUNG SOO [US]

Resumen de: WO2020139863A1

A wind or water flow (hydrokinetic) turbine for harnessing a predetermined minimum or baseload value of renewable electric energy from the wind or water flow energy received at a harnessing module comprises the harnessing module, a controlling module, and a generating module. Han's Principle is that, in a torque balanced three variable Hummingbird speed converter system, from a harnessed input power (input), the generated electric power (output) must exceed the electric power used for the control power (control input) and the input power must exceed the summation of control power and output power. Harnessed input power is provided to a power-balanced three variable mechanical gear control system when a control power of power versus load graph is crossed by an output power line graph to achieve an electrical advantage at a generator output. The three variable mechanical motion control system or "motionics" comprises a Hummingbird control assembly of first and second spur/helical/bevel/miter/ring gear assemblies or Transgear assemblies with an adjustment in between to eliminate variations from constant rotational speed input. The Hummingbird mechanical variable to constant speed control, a control motor and a generator among other components may be mounted on land or a floating platform. Constant electric power at constant frequency are delivered to a variable load.

Solicitante:

VESTAS WIND SYS AS [DK]

Resumen de: WO2020125894A1

A wind turbine comprising a plurality of wind turbine blades, a blade anti-ice system including a blade heating arrangement associated, wherein the anti-ice system includes a 5 control system and a power supply configured to provide power to the blade heating arrangement, characterised in that the power supply comprises a power converter. A benefit of using a power converter to supply electrical power to the heating devices is that power can be applied in a stepless manner. A much finer degree of control is therefore achieved over the thermal energy applied to the blade since the power can be ramped up 10 gradually as the system controller determines that the icing conditions are becoming more severe. As a result of the use of the power converter, the magnitude of thermal energy that is applied to the blade can be increased gradually and smoothly. [Figure 3] 15
