Analysis of DFIG Interval Oscillation Based on Second-Order Sliding Film Damping Control

This paper takes advantage of the high control flexibility and fast response time interfacing power electronic converter for doubly fed wind turbine grid-connected systems to address inter-area oscillations caused by inadequate system damping in systems. A reactive-power-coordinated controller a induction generator (DFIG) is proposed, it makes use second-order sliding-mode technology. The suggested improves performance controlling reactive power. It provides benefits such as quicker rate resilience modeling errors parameter changes. simulation results indicate system’s improved oscillation robustness technique over broad range functional areas.
