Reactive Compensation Techniques to Improve the Ride-Through Capability of Wind Turbine During Disturbance

Transient Stability Improvement of a FSIG Based Grid Connected wind Farm with the help of a SVC and aSTATCOM: A Comparison

“…The gear train used for coupling the generator with the grid is assumed to have infinite stiffness while the friction factor component and the inertia of the turbine is aggregated with these quantities of the electric generator coupled with the turbine [7]- [9].…”

“…The electrical parameters and variables have been referred on the stator side. All the stator and rotor quantities are in two axis d-q reference frame [7]- [9]. The dynamic equations are given as below:…”

Facts Controller for Enhancement of Voltage Stability in Fixed Speed Wind Energy Conversion Systems

“…The STATCOM is based on a solid -state voltage source implemented with an inverter and connected in parallel to the power system through a coupling reactor [12]. A STATCOM consists of an inverter and a DC capacitor as shown in Fig 4. With this arrangement, this device can supply both leading and lagging vars with a small energy storage device.…”

Matrix Converter Interfaced PMSG Based Wind Energy Conversion System Controlled by Adaptive Fuzzy Control System

“…The use of the crowbar is evaluated in [4] and a non-linear controller is designed in [5].The inherent difficulty of ride-through control during a symmetrical grid fault is explained in [6]. In [7], wind-turbine voltage ride-through capabilities were investigated for the squirrel-cage design using different reactive compensation techniques such as fixed capacitor and an SVC, which primarily addresses the support of network voltage during a fault. But, recently matrix converter have got lot of attention by the researchers, because of their robustness and reliability, it is a suitable solution to meet new regulations to ride through real grid conditions in wind energy applications as compared to backto back voltage source converter (VSC).…”
