“…TCBR is special FACTS because it is implemented in dealing with particular problems [12]. Resistor brake strategy was proposed in [13], to alleviate the torsional and inertial oscillatory modes of steam turbogenerator implementing the speed deviation signals from both of the alternator and the prime mover as control signals. In [14], the researcher suggested TCBR strategy based on traditional minimum-time and artificial intelligence strategies to alleviate the subsynchronous resonance (SSR) oscillations using the alternator speed deviation and its derivative as control signals.…”

Oscillation behavior is usually experienced in all power grids as an inherent characterization related to their very existence. Inter-area oscillations are considered to be the most likely to jeopardize the synchronous integrity in power grids. They cause declining the quality conditions of the transmitted power which could have adverse impacts on big consumers' load fed directly from the transmission grid. Therefore, the prime target of this investigation is to alleviate the power oscillations resulting from the different grid disturbances. This aim is accomplished by utilizing a fuzzy based resistor braking strategy taking three energization signals into consideration. Additionally, various time latencies are considered to examine and evaluate the propositioned strategy under these conditions. Also, declined inertia situations resulting from the escalated incursion levels of grid-connected photovoltaic plants are considered to examine the propositioned strategy from a futuristic operational perspective. For examining the effectivity of the propositioned strategy, non-linear time-domain simulation studies are conducted on Kundur benchmark via MATLAB/Simulink platform. Five comparative simulation studies of the benchmark after being subjected to variety of perturbations demonstrate the effectivity of propositioned strategy.

“…Among the multiple presently conceivable SSR mitigation candidates, the dynamic braking resistor (BR) is an extremely effective and relatively cheap mitigation candidate for SSR problems [10][11][12][13][14][15]. BR was initially implemented for augmenting transient stability of electric power systems [1].…”

Subsynchronous resonance (SSR) torsional torque oscillations is a problem of a great concern in the power engineering community. SSR causes torsional torque oscillations with ever-increasing magnitudes occurring in the machine shaft sections causing a premature fatigue life expenditure of the shaft metal. In this paper, dynamic braking switching strategy designed through fuzzy logic control theory and implemented via novel braking resistor model, namely chopper rectifier controlled braking resistor for tempering SSR torsional torque oscillations of a large turbo-generator. The proposed mitigation scheme has been tested on the IEEE second benchmark model for SSR studies. Comparative simulation study via MATLAB/Simulink-based modeling and simulation environment of the test model with and without the suggested mitigation regime should demonstrate its effectuality for mitigation of SSR torsional torque oscillations.

“…Extensive research has been introduced in the literature to increase the damping of torsional mode and many countermeasures have been suggested to damp the SSR. Some suggested solutions include the use of synchronous-machinebased Energy Storage System (ESS) [11], static var compensator (SVC) [12,13], superconducting magnetic energy storage (SMES) unit [14][15][16][17], Static Synchronous Compensator (STATCOM) [18], shunt reactor controller [19,20], Thyristor-controlled dynamic resistance braking [9,21], excitation control of synchronous generator [22,23], and gate controlled series capacitors [24,25].…”

Abstract--This paper investigates the application of Unified Power Flow Controller (UPFC) to stabilize multi-mode torsional oscillations of sub-synchronous resonance (SSR), and to improve the transient stability during a three phase short circuit fault that may result in oscillatory torques on the generator rotor shaft causing serious damages to the system and may call for the disconnection of a wind farm to avoid any possible damages. Simulation is carried out using MATLAB/Simulink software. Results show that the proposed UPFC controller is very effective in damping all SSR modes of the system under study and in minimizing the potential for the wind farm disconnection during the studied faults. The proposed controller is simple and easy to be implemented.
