Susceptibility of wind turbines to sub-synchronous control and torsional interaction

Abstract

This paper investigates the risk of sub-synchronous interaction in wind power plants. Time-domain PSCAD/EMTDC simulation case studies are conducted for the most pessimistic operating condition where the wind power plant becomes radially connected to a weak ac system through a series compensated ac line. Wind turbines of type 1-4 designs are investigated… (More)
