Application of STATCOM to Increase Transient Stability of Wind Farm

Abstract

In this paper we interested to the study the necessary of Facts to increase the transient stability on the presence of faults and the integration of new renewable source, like wind energy, these lasts make the electrical grid operate in a new conditions, the STATCOM is one of the important Facts element, It provides the desired reactive-power generation and absorption entirely by means of electronic processing of the voltage and current waveforms in a voltage source converter (VSC). This function is identical to the synchronous condenser with rotating mass. In present work we propose a transient stability improvement using STATCOM under faults, in the first time we study the transient stability with and without STATCOM for clearly his advantages. In the second time we know the relation between the reactive power injecting by a STATCOM and the critical clearing time, some simulation results are given, commented and discussed.

“…It can significantly provide smooth and rapid reactive compensation for voltage support. It also enhances power oscillation damping and transient stability [9][10][11]. Authors in [2] studied the optimum location and parameters of STATCOM in order to minimize system power loss and to enhance the security of the power system network.…”

Impact of static synchronous compensator on the stability of a wind farm: Case study of wind farm in Tunisia

“…The advantage of this wind turbine is its robustness and electrical simplicity. The rotor speed of generator is fixed independently of the wind speed and it is determined by the frequency imposed by the electrical grid, the gear ratio, and generator conception (Boubekeur et al, 2013). The machine magnetization is ensured by a capacitor battery.…”

“…The STATCOM generates a three-phase alternating voltage in phase with the grid voltage from a DC voltage source by generation/absorption of reactive power (Boubekeur et al, 2013; Ounissa et al, 2013). The amplitude of the generated voltage is controllable (by controlling the state of switches) in order to adjust the amount of reactive power exchanged with the grid.…”
