This book was released on 2020 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the effects of inductive Distributed Flexible AC Transmission System (D-FACTS) device implementations on the performance of different transmission line protection schemes. The reliability and sensitivity of the trip decision of the protection elements is crucial for delivering safe and reliable power to customers. Furthermore, accurate fault location information can help significantly reduce outage duration, operating costs, and the number of consumer complaints. Inductive D-FACTS devices offer a distributed solution for managing and relieving the congestion in transmission lines. However, their interaction with protection and fault location elements may potentially cause unnecessary tripping, relay mis-operation, or misleading fault location information. The operation of these devices may also lead to unpredictable changes in transmission line impedance and fault current limitation due to their dynamic behavior before and during the disturbances. This work studies these negative aspects of D-FACTS devices and proposes solutions and alternatives to mitigate their impact.An inductive D-FACTS model was developed in the ATP version of the Electromagnetic Transients Program (EMTP) and then the steady-state performance of these devices was validated against the existing D-FACTS model in PowerWorld using the IEEE 12 bus test system. Once the model was validated, a more practical system with D-FACTS implementation is simulated using ATP. Lastly, the generated fault event files are played back into commercial relays and a protective relay software model for evaluation.This work examines the influence of two different implementations of inductive D-FACTS on the most common protection elements and schemes under different fault scenarios. The types of D-FACTS devices implementations studied were: dispersed (distributing the D-FACTS along the length of the line) and compressed (distributing them at specific distances on the line). Additionally, the impact of placing D-FACTS devices on adjacent lines was studied. Protection schemes studied in this thesis include distance elements (mho or quadrilateral elements), communication aided distance schemes (permissive overreaching transfer trip [POTT]), and fault location schemes. Furthermore, the influence of fault resistance and mutual coupling between parallel lines on relay response is studied in the presence of D-FACTS devices.Dispersed or compressed D-FACTS implementation can cause underreaching of distance elements. This may lead to a delay in the tripping time or in fact, a failure to trip in a POTT scheme. The simulation results show that using dispersed D-FACTS implementation can reduce the error compared to the compressed implementation, and increase the ability of performing correction for these devices under some operating conditions. This work also examined the effect of D-FACTS devices on distance elements' performance in presence of a fault resistance and mutual coupling between the parallel lines. The results illustrated how the direction of the power flow influences the fault resistance coverage of distance elements in the presence of D-FACTS devices. The D-FACTS may help to reduce the distance elements' underreach for forward faults and increase the underreach behavior for the reverse fault. The results show that mutual coupling influence on distance elements would be not impacted by addition of the D-FACTS devices.Lastly, we investigated how implementing inductive D-FACTS devices on the adjacent line affects the dynamic behavior of mho distance elements and the calculated effective impedance tilt of quadrilateral distance elements' response. Inserting the D-FACTS behind the relay can help expand the mho circles for forward faults and contract them for reverse faults. As a result, fault resistance coverage can be improved. On the other hand, this may cause underreaching or overreaching of the quadrilateral distance elements' response when a fault resistance is present in a ground fault.To deal with the challenges in the implementation of D-FACTS devices and minimize their influence on transmission line protection system performance, this thesis proposes mitigation for creating reliable protection and fault location schemes. The work concludes by offering recommendations for D-FACTS device implementation and protective relays' settings.

This book was released on 1995 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis examines how Flexible AC Transmission Systems (FACTS) devices can improve the secure-economic operation of a power system. More specifically, the benefits of FACTS devices in a network are evaluated in terms of four areas of power system study: system security, economic dispatch operation, maximum network loadability and electric industry deregulation. Simulations of a simple network are made to evaluate how a FACTS device can be used to increase the security region of a network. Based on this analysis, simulations are performed using the 24-bus IEEE reliability test network to assess the possible savings in generation costs, the increase in maximum network loadability and the improvements in flexibility of exchanges resulting from the use of a FACTS device in this network. The results demonstrate that FACTS devices can be used effectively to increase the security region of a network thereby allowing for a better optimum operating point in any optimization problem performed over such a region." --

Download or read book D FACTS for Improved Reliability of the Transmission System During Contingencies written by Alex Corredor Corredor and published by . This book was released on 2016 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on an investigation of the impact of a limited number of D-FACTS devices on typical power lines that utilities have within their grids. The D-FACTS devices do not require space in a substation and have reduced costs compared to rewiring an existing line or installing a new line. The device is designed to clamp onto existing power lines and therefore assist in power flow without the necessity of redesigning existing power delivery systems. The lines are modeled appropriately with existing data from the WECC. Then D-FACTS devices are modeled and integrated with line models for appropriate simulation studies. This process uses commercial software for simulation. Applying these models to existing operating conditions yields predictions of device performance within the grid and identifies appropriate degrees of compensation. Finally, analysis of these results will be used to give some recommendations for modifying the specific system at hand using D-FACTS devices.
