Influence of Wind Farm with PMSG Type on Small Signal Stability of Power System

Article Preview

Abstract:

In order to study the small signal stability of power grid after grid-connection of large-scale Permanent Magnet Synchronous Generator (PMSG) wind farms, the mathematical model of PMSG was established. By means of simulation on a simple power system, the damping characteristics of grid under different wind power penetration and different access location of wind farms were studied in detail. Simulation results show that along with the increase of wind power, the inter-area oscillation mode damping would reduce. When wind farm was attached the receiving area, the inter-area oscillation mode damping was lower than it when wind farm was attached the supplying area.
