Download or read book Static and Dynamic Impact of High Voltage Direct Current HVDC in AC Power Transmission System written by Mohd Irwan Mohd Salleh and published by . This book was released on 2009 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: High voltage direct current(HVDC) is very suitable for AC transmitting power over very long distances.It is more economical for long distances of transmitting of transmitting power. Since the cost of an HVDC transmission line is less than that of an AC line with the same capacity, the additional cost of converters for DC transmission is offset when the line is long enough. Studies show that it is advantageous to consider overhead HVDC transmission lines when the transmission distance is longer than 600 km. HVDC lines have no reactance and are capable of transferring more power for the same conductor size than AC lines. DC transmission is especially advantageous when two remotely located large systems are to be connected. The DC transmission tie line acts as an asynchronous link between the two rigid systems eliminating the instability problem inherent in the AC links.This project will determine or analysis the impact of load flow,fault and stability by using Power System Computer Added Design(PSCAD).So,the stability and load flow of the system can be determined.Load flow study are used to ensure that electrical power transfer from generator to consumer through the grid system is stable,reliable and economic.The result from this analysis can be used to make another research related to the power flow which familiar as power system stability analysis.

This book was released on 2020-12-10 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric power transmission relies on AC and DC grids. The extensive integration of conventional and nonconventional energy sources and power converters into power grids has resulted in a demand for high voltage (HV), extra-high voltage (EHV), and ultra-high voltage (UHV) AC/DC transmission grids in modern power systems. To ensure the security, adequacy, and reliable operation of power systems, the practical aspects of interconnecting HV, EHV, and UHV AC/DC grids into the electric power systems, along with their economic and environmental impacts, should be considered. The stability analysis for the planning and operation of HV, EHV, and UHV AC/DC grids in power systems is regarded as another key issue in modern power systems. Moreover, interactions between power converters and other power electronics devices (e.g., FACTS devices) installed on the network are other aspects of power systems that must be addressed. This Special Issue aims to investigate the integration of HV, EHV, and UHV AC/DC grids into modern power systems by analyzing their control, operation, protection, dynamics, planning, reliability, and security, along with considering power quality improvement, market operations, power conversion, cybersecurity, supervisory and monitoring, diagnostics, and prognostics systems.

Download or read book FACTS and HVDC Systems for Enhancing Tie line Power Transfer Capability written by Abdussalam S. Elansari and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the use of flexible AC transmission systems (FACTS) and voltage source converter (VSC) high-voltage direct current (HVDC) transmission systems for improving the power transfer capability of the Libyan internal tie-line between east and west, for a secure, reliable and efficient operation of this power corridor. Mathematical-based analysis supported by numerical-based analysis, which employs NEPLAN power system analysis tool, are carried out to investigate the steady state and dynamic behaviour of the power system.Different FACTS technologies, including variable impedance based and converter-based shunt and series FACTS devices, are studied during steady-state and transient operating conditions to evaluate the capabilities, control systems and weaknesses in these technologies. The investigations focus on the common types of shunt and series FACTS including: the static VAr compensator, static synchronous compensator, and thyristor controlled series compensator. A challenge in this thesis is to find an efficient method to allocate and size FACTS devices, to ensure maximum utilization of the tie-line considering technical constraints including:; voltage rise at a point of voltage collapse, equipment terminal voltage and subsynchronous resonance risk.For the VSC-HVDC system, a mathematical model that calculates power flow throughout the HVDC link and at both AC sides is confirmed as an efficient steady-state model facilitating estimation of reactive power requirements at the converter terminal and at the point of common coupling. This model can be used to estimate the optimal converter rating based on the system strengthens at both sides. Further modelling and analysis investigates the operation of a hybrid AC/DC system. Multi-tasking control systems for voltage source converter HVDC systems are used to facilitate operation of the hybrid AC/DC system during normal and emergency operating conditions. The controllers include: frequency control in the case of an unsynchronized connection and power management control necessary to balance the power flow during an emergency, in additional to the primary control of the AC and DC voltages, and active and reactive powers.Well-known and referenced two areas Kundur test system with a weak tie-line, which suffers from a limited power transfer capability between the operating areas, is used throughout the analysis. the tie-line between two regions in the Kundur test system is investigated when incorporating different FACTS technologies and a VSC-HVDC system. Based on the introduced approaches and models the benefits and challenges of these technologies in the Libyan internal tie-line are explored. The research shows that the power transfer capability of the tie-line can be improved by shunt and to a lesser extent, by series compensation. Comparison between FACTS devices and VSC-HVDC indicates, apart from the cost, VSC-HVDC transmission may be the better option for Libyan internal tie-line improvement, especially in the near future, when secure and reliable interconnected power system is required.
