This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparison among series connected auxiliary devices; SFCL, DVR, TCSC, and SDBR is performed in terms of fault ride through capability improvement of a fixed speed wind generator systems, controller complexity, and cost. The tested system consists of one synchronous generator and one squirrel cage induction machine based wind generator, which feed an infinite bus through a double circuit transmission line. Simulation results show that all the devices performs well under symmetrical and unsymmetrical faults, however, in spite of the DVR controller complexity it has the best performance among all devices in terms of voltage, and speed control of wind generators at lower cost as compared to the SFCL which is costliest among all devices. The SFCL is the most efficient in reducing the fluctuations of active power and stator current of the wind generators. The SDBR is the cheapest, and shows a better enhancement in damping active power and limiting fault current than DVR and TCSC.
Book Synopsis Transient Stability Improvement of DFIG Based Variable Speed Wind Turbine Generator System Using DC Resistive Fault Current Limiter by : Md Maruf Hossain
Download or read book Transient Stability Improvement of DFIG Based Variable Speed Wind Turbine Generator System Using DC Resistive Fault Current Limiter written by Md Maruf Hossain and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Presently, the doubly fed induction generator (DFIG) is the most popular technology to harness the wind power due to its ability to adapt to variable wind speed and to capture more wind energy. However, the DFIG based variable speed wind generator is vulnerable to faults, as the stator of the DFIG is directly connected to the grid. Both symmetrical and asymmetrical faults may cause the DFIG face high mechanical stress, which may lead to mechanical damage. According to the grid code, the transient stability enhancement of the DFIG system is very important. Though the DFIG has a salient feature of the fault ride through capability, this is not sufficient to preserve the regulations of the grid code at all situations. In this dissertation, in order to enhance the transient stability of the DFIG based variable speed wind generation system, first the performance of the different types of internal controlled devices such as, crowbar, DC chopper and parallel capacitor with the DC link of DFIG system has been investigated. From the analysis, it is established that the internal controlled devices cannot maintain the grid code during all types of network faults. This testifies the importance of the application of the auxiliary devices to enhance the transient stability of the DFIG based wind generator system. An investigation has been made to explore a device which could provide the best performance in terms of transient stability enhancement for a grid-connected DFIG system during faults. Ultimately, a DC resistive superconducting fault current limiter (SFCL) is proposed because of its best performance. The DC resistive SFCL reduces the system power losses during stable operation of the network with improved system efficiency, in comparison with the conventional SFCL. One of the salient features of using the SFCL is that it does not require any controller, and immune to any sort of cyber threat or vulnerability. To verify the transient stability performance of the DFIG based wind generator system with the proposed DC resistive SFCL, both the symmetrical and asymmetrical faults are considered. The performance of the DC resistive SFCL is compared to that of the series dynamic braking resistor (SDBR) and the conventional SFCL. Simulations are carried out by using the Matlab/Simulink software. Simulation results clearly indicate that the proposed DC resistive SFCL shows the best performance to enhance the transient stability of the DFIG based wind generator system.

Book Synopsis Fault Ride-Through Capacity Enhancement of Fixed Speed Wind Generator by A Modified Bridge-type Fault Current Limiter by : Gilmanur Rashid
Download or read book Fault Ride-Through Capacity Enhancement of Fixed Speed Wind Generator by A Modified Bridge-type Fault Current Limiter written by Gilmanur Rashid and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault Ride-Through (FRT) is a common requirement to abide by grid code all over the world. In this work, to enhance the fault ride-through capability of a fixed speed wind generator system, a modified configuration of Bridge-Type Fault Current Limiter (BFCL) is proposed. To check the effectiveness of the proposed BFCL, its performance is compared with that of the Series Dynamic Braking Resistor (SDBR). A harmonic performance improvement by the proposed method is also analyzed. Three-line-to-ground (3LG), line-to-line (LL) and single-line-to-ground (1LG) faults were applied to one of the double circuit transmission lines connected to the wind generator system. Simulations were carried out using Matlab/Simulink software. Simulation results show that the proposed BFCL is very effective device to achieve the FRT and suppress fault current that eliminates the need for circuit breaker replacement. Also, the BFCL improves the harmonic performance and helps follow harmonic grid code. Moreover, it was found that the BFCL works better than the SDBR, and has some distinct advantages over the SDBR.
Book Synopsis Voltage Stability Enhancement of Wind Generator System Using Superconducting Fault Current Limiter by : Arnab Banik
Download or read book Voltage Stability Enhancement of Wind Generator System Using Superconducting Fault Current Limiter written by Arnab Banik and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind generator systems have stability problems during network faults. The superconducting fault current limiter (SFCL) has the ability to prevent the magnitude of short-circuit current from increasing. This work proposes the SFCL device to enhance the voltage stability of a fixed-speed wind generator system.In this work the performance of SFCL is compared to that of the thyristor switched capacitor (TSC) method and the pitch control method. The comparison is done in terms of voltage stability enhancement, controller complexity and cost. The effectiveness of the proposed methodology is tested considering permanent and temporary, balanced and unbalanced faults in the power system model consisting of a wind generator and a synchronous generator.From the simulation results it is evident that performance of SFCL is better. On comparison it can be concluded that SFCL performs better when compared to TSC or pitch control method. Simulations are performed through Matlab/Simulink software.
