Power Flow and Transient Stability Improvement by Static Synchronous Series Compensator

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1517
Md. Imran Azim , Md. Abdul Wahed , Md. Ahsanul Haque Chowdhury
In the present world, modern power system networks, being a complicated combination of generators, transmission lines, transformers, circuit breakers and other devices, are more vulnerable to various types of faults causing stability problems. Among these faults, transient fault is believed to be a major disturbance as it causes large damage to a sound system within a certain period of time. Therefore, the protection against transient faults, better known as transient stability control, is one of the major considerations for the power system engineers. This paper presents the control approach in the transmission line during transient faults by means of Static Synchronous Series Compensator (SSSC) in order to stabilize Single Machine Infinite Bus (SMIB) system.  In this paper, SSSC is represented by variable voltage injection associated with the transformer leakage reactance and the voltage source. The comparative results depict that the swing curve of a system increases monotonically after the occurrence of transient faults However, SSSC is effective enough to make it stable after a while. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.8075

Chinnapettai Ramalingam Balamurugan , S.P. Natarajan , T.S. Anandhi , B. Shanthi
This paper proposes a nine level cascaded multilevel inverter based on the flip flops and logic gates. Generally multilevel inverter is used to achieve the high power by using a series of power semiconductor switches with the several dc voltage sources which is used to perform the power conversion. In this paper the flip flop based CMLI is compared with the conventional CMLI. The flip flops and logic gates are used to create logic equation for the each switch of the CMLI by using the switching states. This proposed topology is mainly used to reduce the total harmonic distortion and also increase the performance of the system. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.7978

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1527
Mitra Khaledian , Mohammad Bagher Menhaj
This paper introduces a new algorithm based on machine vision for the recognition of hand gesture. In step 1, the Microsoft Kinect sensor is used to capture color images and depth. User’s hand detected by eliminating the background and rescaling image. In the next step, “Scale-invariant feature transform (SIFT)” algorithm is used for the feature extraction. The extracted feature vectors are built in vocabulary tree with K-means clustering. Finally, Hand gesture is recognized by a recognition high-level method called stochastic context-free grammar (SCFG). SCFG is used for syntactic structure analysis that is based on hand gesture recognition, that is combined postures can be analyzed and recognized by a set of production rules. SCFG is most effective in disambiguate. By this approach, we are able to recognize various gestures in 30 frames per seconds (fps) and with more than 90 % accuracy. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.8091

Multilevel MPSoC Performance Evaluation: New ISSPT Model

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1518
A. Alali , I. Assayad , M. Sadik
To deploy the enormous hardware resources available in Multi Processor Systems-on-Chip (MPSoC) efficiently, rapidly and accurately, methods of Design Space Exploration (DSE) are needed to evaluate the different design alternatives. In this paper, we present a framework that makes fast simulation and performance evaluation of MPSoC possible early in the design flow, thus reducing the time-to-market. In this framework and within the Transaction Level Modeling (TLM) approach, we present a new definition of ISS level by introducing two complementary modeling sublevels ISST and ISSPT. This later, that we illustrate an arbiter modeling approach that allows a high performance MPSoC communication. A round-robin method is chosen because it is simple, minimizes the communication latency and has an accepted speed-up. Two applications are tested and used to validate our platform: Game of life and JPEG Encoder. The performance of the proposed approach has been analyzed in our platform MPSoC based on multi-MicroBlaze. Simulation results show with ISSPT sublevels gives a high simulation speedup factor of up to 32 with a negligible performance estimation error margin. DOI:  http://dx.doi.org/10.11591/telkomnika.v15i1.8085

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1521
Ben Ahmed Mohamed , Boudhir Anouar Abdelhakim , Bouhorma Mohammed , Ben Ahmed Kaoutar
Urban road traffic is the heart of many problems: more recent years, this critical aspect involved every day is unfavorable to many fields, such as economics or ecology. For these reasons, the Intelligent Transportation Systems (ITS) have emerged to best optimize the expenditure of the user on often complex road networks. In this paper, after studying the backgrounds of such systems, we propose a system of control of traffic lights through the use of statistical multiplexing technique based on fixed and vehicular networks of wireless sensors. We will see that this architecture can be flexible within the framework of ITS and participate in low cost to obtain interesting results. The simulation results prove the efficiency of the traffic system in an urban area with an adaptable and dynamic traffic road, because the average waiting time of cars at the intersection is sharply dropped when the red light duration is 65 s and the green light time duration is 125 s. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.8092

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/1514
G. Sridhar , P. Satish Kumar , M. Sushama
Applying pulse width modulation (PWM) techniques for cascaded multilevel inverters are very complex for topologies with reduced number of switches. In this paper for phase disposition (PD) pulse width modulation technique a new algorithm is proposed and implemented on eleven level cascaded multilevel inverter under reduced switches topology. In the proposed algorithm instead of   N-1 carrier waves, the required number of switching pulses generated by considering number of carrier waves is equal to number of switches. This technique allows lower switching transition and it leads to reduced switching losses for topologies utilize minimum number of switches. 1.2 KHz carrier frequency is used to generate switching pulses and verified up to 100 kHz. The Total harmonic distortion is observed for various switching frequencies. The obtained output voltage levels using PD PWM technique proved mathematically. The performance of proposed algorithm is evaluated using Matlab/Simulink. DOI: http://dx.doi.org/10.11591/telkomnika.v15i1.8076
