“…The maximum reactive power is an inverse function of the voltage thus their usefulness decreases when they are needed the most in a power system. The use of the SVC to improve a power system's voltage stability under normal and during system disturbances such as line outages and line faults [10] and for rotor angle stability improvement [11] have been widely studied. The static synchronous compensator (STATCOM) is based on the DC-AC switching converter.…”

<p>Flexible alternating current transmission system (FACTS) devices are deployed for improving power system’s stability either singly or as a combination. This research investigates hybrid FACTS devices and studies their impact on voltage, small-signal and transient stability simultaneously under various system disturbances. The simulations were done using five FACTS devices-static var compensator (SVC), static synchronous compensator (STATCOM), static synchronous series compensators (SSSC), thyristor controlled series compensator (TCSC) and unified power flow controller (UPFC) in MATLAB’s power system analysis toolbox (PSAT). These five devices were grouped into ten pairs and tested on Kenya’s transmission network under specific contingencies: the loss of a major generating machine and/or transmission line. The UPFC-STATCOM pair performed the best in all the three aspects under study. The settling times were 3 seconds and 3.05 seconds respectively for voltage and rotor angle improvement on the loss of a major generator at normal operation. The same pair gave settling times of 2.11 seconds and 3.12 seconds for voltage and rotor angle stability improvement respectively on the loss of a major transmission line at 140% system loading. From the study, two novel techniques were developed: A performance-based ranking system and classification for FACTS devices.</p>

“…The analysis of publications shows that the shunt-connected reactive power compensators based on the TSC and TCR is developed only for the symmetric compensation of the reactive power and practically is employed just for high and medium voltage lines of the utility grid (Acha, 2002;Čerňan & Tlustý, 2015;Chang & Liao, 2017;Dixon et al, 2005;Farkoush et al, 2016;Fuchs & Masoum, 2011;Hong Hu et al, 2015;Igbinovia et al, 2015;Ilisiu & Dinu, 2019;Liberado et al, 2013;Liu et al, 2016;Mathur & Varma, 2002;Padiyar, 2007;D.

“…The switched-based SVC present a vital solution to remove the harmonics during the control of the reactive power. But, it should be considered that, the switched SVCs have discrete performance during the control of reactive power; consequently, they require different control and design methodology to obtain the smoothest characteristic [12].…”

This paper analyzes the process of reactive power compensation using thyristors switched capacitors TSC topology based on multiterminal switch during the starting of induction motor. The paper explains the control principle of this TSC topology which depends on the multiterminal switch. To actively track the required reactive power for the dynamic load and to perfectly transit from it from one level to other, proper control system is established. MATLAB/SIMULINK is used to develop a simulation model to prove the dynamic performance of the proposed TSC during the compensation of reactive power required for induction motor during starting.
