Non-grid-connected Wind Power DC Network Study Based on Hybrid Convertor

摘要

Applying non-grid-connected wind power to high energy consuming industry has broad development prospects.This paper presents a compound DC power transmission net to realize high efficiency and reduce the loss.This net consists of current source converter (CSC) based on naturally commutated thyristor and voltage source converter (VSC) based on IGBT.Super capacitor connected to the load side stabilizes the wind power fluctuation.The coordinated control strategy of wind power,energy storage device and load is provided.Simulation results based on real wind power shows the validity of the system.
