To understand and quantify the performance of the permanent magnet linear synchronous generator we need a mathematical model of the incoming ocean wave.
In both the simple and complex models the incident ocean wave is assumed to be sinusoidal, and in the simple model we assume that the ocean wave elevation is unaffected by the WEC.
These are strong assumptions.
In reality, ocean waves are irregular.
An irregular incident wave field can be modeled as a linear superposition of a finite number of regular, or sinusoidal, wave
components [8, 10].
This model is not identical to the real situation, but this simplification allows us to understand how the general model will work.
We can understand, through this simplified model, how the PTO will transform the
kinetic energy in the incoming ocean wave into electricity
