“…These unstable frequencies increase the phenomenon of sub synchronous resonance [16]. Without the control of TCSC and AVR also, at different levels of compensation, we observe that torsional frequencies have unstable roots, note that four are different levels of compensation magnitude.…”

This research shows that when connecting a generator and steam turbines to a transmission line that has series capacitive compensation, this may cause many problems, including the emergence of a sub-synchronous resonance state. The Flexible Ac Transmission System (FACTS) controller of the devices wide use which has been used to reduce and suppress the phenomenon of sub-synchronous resonance the Thyristor Control Series Compensation (TCSC) is one type of FACTS controller that has been used to put down the SSR. The first standard model of IEEE was adopted to study this phenomenon. Linear Quadratic Gaussian (LQG) was used to design TCSC strong to dampen this phenomenon in the energy system. Reduce-Order version of this controller is also obtained. Non-linear systems simulations are used to achieve a better control unit to dampen all oscillations in a very short time. In this paper, we also examine the process of controlling the parameters of TCSC and AVR through the use of PID controller To achieve a process of suppression of this phenomenon. In this research, the method of Eigenvalue was used to analyze the sub-synchronous resonance phenomenon and the result was verified using DYMOLA simulation.

“…The regulator in SVC type-II [13,14] is a twin lead-lag type for providing compensation for the time delays in the firing circuit and due to phase sequence dead time delay of zero crossing. The VAR regulator is proportional plus integral in SVC type-III [15,16]. The Simulink block diagrams of IEEE type-I excitation system and SVC type-I, -II, and -III have been shown in Figure 5(a), 5(b), 5(c), and 5(d), respectively.…”

This article presents reactive power control of autonomous wind-diesel hybrid power system for realistic load disturbance using Simulink. The simulation block diagram of wind-diesel, multi-wind-diesel, and wind-multi-diesel hybrid system based on Simulink is developed. Reactive power control performance is compared using three different types of static VAR compensator (SVC) models. Reactive power performance is also compared for wind-diesel, multi-wind-diesel, and wind-multidiesel hybrid power systems.
