Flexible Alternating Current Transmission

Flexible alternating current transmission systems are used since nearly four decades and present very good dynamic performances. The purpose of this work is to study the behaviour of a system where static compensator (STATCOM) is located at the midpoint of a long transmission line functioning in disturbed modes with various levels of load caused by tripping and then, reclosing of the incoming station breaker. The studied model and starting from the analysis of various alternatives will lead to the checking of the aptitude of the STATCOM to maintain the voltage plan and to improve the power flow in electro-energetic system which is the east region of Algerian 400 kV transmission network. The steady state performance of STATCOM’s controller is analysed through computer simulations with MATLAB/Simulink program. The simulation results have demonstrated that STATCOM can be effectively applied in power transmission systems to solve the problems of poor dynamic performance and voltage regulation.   Keywords: STATCOM, reactive power, power flow, voltage plan, breaker automatic recloser.

Reactive Power Compensator

The work presented in this paper is a contribution to the problem of controlling the reactive powers and the voltages in an electrical network. Among these control tools, the static reactive power compensator (SVC) has been chosen because of its simplicity of control. The SVC is among the FACTS 'Alternative Flexible Current Transmission Systems' devices that help to deal with problems encountered in the operation of electrical networks either in the distribution side or in the transport side. In this work, the SVC is used to control the reactive power and the voltage in an electric power transmission network. In order to improve its efficiency, three voltage regulation systems have been chosen in the control system of this compensator.

Reactive Power Planning

AbstractThis paper formulates and solves a techno-economic planning problem of reactive power (VAR) in power transmission systems under loadings. The objective of the proposed research work is to minimize the combination of installation cost of reactive power sources, power losses and operational cost while satisfying technical constraints. Initially, the positions for the placement of reactive power sources are determined technically. Different cost components such as VAR generation cost, line charging cost etc. are then added in the total operating cost in a most economical way. Finally, the optimal parameter setting subjected to reactive power planning (RPP) is obtained by taking advantages of hybrid soft computing techniques. For the justification of the efficiency and efficacy of the proposed approach the entire work is simulated on two inter-regional transmission networks. To validate the robustness and ease of the soft computing techniques in RPP the responses of benchmark functions and statistical proof are provided simultaneously.
