Frequency and time domain modeling and power output for a heaving point absorber wave energy converter
Considering the offshore conditions and climate, a point absorbing WEC with a direct drive PTO system is the most efficient and beneficial in con- verting the low-speed oscillating motion of Gulf of Mexico (GoM) waves .
Frequency/time domain modeling of a direct drive point absorber wave energy converter
The present study is related to a point absorber WEC with direct drive PTO ; the PTO damping is modeled to be linear.
Power electronics as grid interface for actively controlled wave energy converters
This factor will be determining for the power take off (PTO) system and will directly affect the dimensioning of the generator and power electronic interface if a direct drive PTO is the chosen solution.
Large-scale ocean wave energy plant modeling
For example the modularity of these systems easily allows a developer to compare how their device performs with a direct drive PTO compared to its performance with a hydraulic PTO.
Development and characterization of a novel direct drive rotary wave energy point absorber MTS-IEEE oceans conference proceedings
A direct drive PTO is best described as a direct connection between the moving bodies of the WEC and the generator.
The efficiency is expected to be relatively high and in order to give an order of magnitude, the stated efficiency by the Danish Wave energy program for direct drive PTO systems is 0.85 .
The following table shows the default efficiency values for the hydraulic, water, air, mechanical and direct drive PTO systems (Nielsen, 2003): .
Power conditioning of the output from a linear vernier hybrid permanent magnet generator for use in direct drive wave energy converters
In a direct drive PTO system the wave energy device, such as a heaving buoy or Archimedes wave swing , is directly coupled to the translator of a linear electrical generator, which moves relative to stationary coils mounted on the moored stator.
Device survival possibilities are increased because of the direct drive PTO system.
