Wave-Energy Conversion Chain — FOC & Grid Injection

Simulation of a wave-energy conversion chain using a PMSG, field-oriented control and grid-side injection.

IEC 61000
Wave-Energy Conversion Chain — FOC & Grid Injection
PROJECT CONCEPT VIEW

The visual reads the model as an energy path: wave motion is converted into mechanical rotation, the PMSG produces variable electrical power, and the power-electronic stages condition that power before a synchronized grid-side converter delivers it to the network.

Problem

Wave input is variable; the electrical chain must regulate power without pretending the source is stable.

Solution

A PMSG conversion model with field-oriented control and grid-injection logic.

Build path

  1. Model the mechanical-to-electrical conversion chain.
  2. Set the machine-control assumptions.
  3. Connect the control loop to the grid-side stage.
  4. Discuss the limits of the simulation.

Discussion

The project connects renewable-energy modelling with machine-control practice and shows where variability enters the system.
