Impact Of Statcom On Voltage Stability Of Fixed Speed Wind Farms

There has been a significant growth in the development of wind energy systems leading to a gradual shift from the fixed speed wind turbines (FSWT) to the variable speed wind turbines (VSWT). Despite this gradual shift in wind turbine systems, the fixed speed wind generator turbines still account for a non-negligible percentage of wind turbines across the globe. One of the reasons for this gradual shift from the fixed speed wind generators is its poor reactive power management and voltage instability under grid fault conditions. This paper investigates a fixed speed wind farm under a grid fault condition and the impact of the static synchronous compensator (STATCOM) in improving the voltage stability of the wind farm. The results show that the presence of a STATCOM device in a fixed speed wind system greatly improves the voltage stability of the system in both transient and steady state conditions.
