The paper presents the design of fuzzy logic controller (FLC) for enhancing the performance of power system under fault condition. In a power system, several types of fault may occur which causes the system to lose stability. The fault considered in this paper is a three phase short circuit fault which occurred on one of the transmission line. The objective is to improve the performance of the system during and after the fault by using fuzzy controller. The performance of different controllers has been compared and it is found that a better and smoother output is obtained by fuzzy controller.

Now a days every industry needs more income with less investment behind infrastructure. Here, the new era of Cloud computing comes where the user can have everything on rent and "pay as go" fundamental. Cloud users are able to store their valuable data on Cloud premises and make themselves free from local burden. While users data is available on Cloud servers, it is very important for the user that data must be secure when it is in transition and even after it has been stored on server. Most of the researchers think for the user centric(side) scenario i.e mainly consider the security issue related to Cloud users like Integrity checking, Authentication, Versioning Etc. On the other hand, some researchers provide their view related to working of Cloud service providers i.e. Database encryption, Security based on Metadata, Data Obfuscation Etc. To have proper confidentiality, Security and integrity of data, this paper presents two techniques, that is: Encryption, authentication at client side as well as Data Obfuscation at server side. Encryption helps user to provide secrecy to its data when it is transferred in the network. Data obfuscation helps service provider to secure the users data on his premises. By applying these two techniques, the user and Service provider gets maximum protection against intruders and unauthorized access.

Gradient Kalman Filter (GKF) is designed for an effective restoration of Endoscopic frames. The combine advantages of Kalman filter and Gradient distribution restore highly degraded Endoscopic frame with Random noise and blur simultaneously. Kalman filter shows the advantage of the effective restoration of `high-frequency' region and Gradient filter shows the advantage of the effective restoration of `low-frequency' region without altering `high-frequency' region. Experimental results show that the proposed method improves frame quality in terms of parameters like PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error) and SSIM (Structure Similarity Index Measurement) as compared to conventional methods.

Engineering classes are operating today in the same format as they were fifty years back. The difference in the past decade has been the emergence of the Internet and its rapid usage right outside the walls of the class. Harvard University and MIT's path-breaking collaboration in initiating Massive Online Open Courses (MOOCs) has raised the global standard and reach of education today. The race is a long-drawn one, since we are no longer competing just to stand at the top as educationists, but rather to stand out in terms of the extent to which we can provide the best and most outstanding resources to our students in the face of a fast-changing world. But are we still going to follow what was given to us, or do we have a chance to start our own revolution? The answer to this lies in how we look at engineering education at this point in time. Engineering is the budding field of industrialists of tomorrow. So why can we not bring industrial experience right into our classrooms? The most effective method of learning a concept is to get a first-hand experience of its application. Such an experience would not just enhance the quality of our engineering classrooms, but also offer the students an unforgettable experience and the motivation to become efficient and responsible engineers of tomorrow. This paper presents a conceptual model of how to effectively implement this idea within the existing organizational structure, so as to implement a smooth transition to smarter and richer modules of engineering education.

A Transformer is one of the most important and expensive devices in a power system. This paper presents new, simple and common method for transformer protection based on percentage biased differential principle. Fast Fourier Transform (FFT) technique is used to provide the operating quantity to the dual slope differential relay. The operating criterion of the relay depends on the relationship between differential current (IDIFF) and restraining current (IREST). Various power system components such as generator, transformer, loads, relay, etc. have been modeled in PSCAD/EMTDC software package. The proposed differential protection scheme of transformer operates only for the internal fault which includes ground and phase faults. The scheme remains stable and does not operate for any fault outside the transformer as well as during normal load condition. Moreover, it operates for high resistance in-zone fault and is unaffected by Current Transformer (CT) saturation in case of an external fault. The proposed method is implemented for different transformer configurations such as Star-Star, Star-Delta, Delta-Delta and Delta-Star. Simulation results and relay response for different types of fault are included in the paper.

In the past few years the demand for high capacity optical transport platform is rapidly increasing. It has drawn the attention of the researchers. The optical networks with the capacity of the order of Tbps are evolving. The capacity of individual optical channel is increasing towards 100 Gbps and beyond. In this paper, we demonstrate design and performance of 1.92 Tbps WDM Optical System. Three CW lasers are used to generate optical carriers. Twelve sub carriers, each spaced 80 GHz apart are produced using two dual tone generators. Each subcarrier carries information at transmission rate of 160 Gbps to enhance the spectral efficiency to 2 b/s/Hz. The analysis is carried out for 12 × 160 Gb/s (1.92 Tb/s) PDM-QPSK WDM optical system considering three different cases that is without coding, with gray coding and with differential coding for 100 km transmission distance. Extensive simulations are carried out to evaluate symbol error rate, error vector magnitude and Q-factor in each case. From the comparison, it is observed that the system with differential coding gives better performance in comparison with other two cases. An improvement in Q-factor with differential coding is achieved in the range of 2 to 5 dB with respect to other two cases. It is also shown that the transmission distance for PDM-QPSK WDM optical system with differential coding can be extended upto 8000 km keeping the Q factor above the FEC limit requirement (BER value 3.8 × 10-3).

BiCMOS bandgap reference (BGR) has advantage over MOS based BGR in terms of its accuracy at its reference output and very less temperature coefficient (TC). This paper presents bandgap reference circuit with folded cascode operational amplifier (op-amp) in order to improve the stability of final VREF output. The temperature stability of output can be improved by using trimming circuit in voltage mode architecture of bandgap reference operating with less power consumption. Using only first order temperature compensation technique, the proposed circuit gives output voltage of 1.181V with 0 °C to 100 °C temperature variations that corresponds to TC of 19ppm/ °C. The output reference voltage exhibits line variations of 2.4mV/V with supply range of 1.62V to 1.98V at typical process corner. A single stage folded cascode op-amp that is included in the proposed bandgap improves the stability of output voltage in closed loop, power supply rejection ratio (PSRR) of BGR and input common mode range. The proposed circuit includes start-up circuit to avoid start-up problem because of closed loop, the reference current for op-amp is generated from BGR current mirror and impact of its TC on final VREF is negligible. The simulation results shows that PSRR of proposed BGR is -43db from dc to 30KHz frequency, Phase margin (PM) is 70°, input offset of op-amp is 1.96μV and closed loop gain of op-amp in BGR is 118dB. The total current for overall BGR is 12μA and total power consumption is 18.4μW. The proposed bandgap reference is simulated using Mentor-Graphics Pyxis tool, Eldo-Spice simulator in 130nm CMOS technology. The proposed BGR output is used in low-drop-out (LDO) regulator circuit that is operating at 3.3V supply and gives regulated output of 1.8V.

Voltage Stability and Voltage Security are considered as important concerns in power system planning and operation. To provide reliable, secure and stable electrical power to the customers, is the main task of power system engineer. To meet these requirements simultaneously, the power system is to be operated closer to its stability limits which cause more stress on the power system. Therefore, a study that determines the maximum power transfer capability of the power system before voltage collapse must be carried out in the voltage secured environment. This paper presents the evaluation of some of load flow based static voltage stability indices which are found during the literature survey to present reliable information about the closeness of the power system to voltage collapse. The comparison of these indices is presented here and their effectiveness has been tested on various standard IEEE busbar test systems using several different scenarios of load increase. The results of standard IEEE14 busbar test system have been demonstrated specifically. The novelty of the work presented here lies in the method of load increase scenario using a special code written in MATLAB environment. Furthermore, a novel idea of the use of line voltage stability indices to predict voltage collapse within the framework of a voltage security is presented in this paper.
{"title":"Load flow based voltage stability indices to analyze voltage stability and voltage security of the power system","authors":"A. S. Telang, P. Bedekar","doi":"10.1109/NUICONE.2015.7449638","DOIUrl":"https://doi.org/10.1109/NUICONE.2015.7449638","url":null,"abstract":"Voltage Stability and Voltage Security are considered as important concerns in power system planning and operation. To provide reliable, secure and stable electrical power to the customers, is the main task of power system engineer. To meet these requirements simultaneously, the power system is to be operated closer to its stability limits which cause more stress on the power system. Therefore, a study that determines the maximum power transfer capability of the power system before voltage collapse must be carried out in the voltage secured environment. This paper presents the evaluation of some of load flow based static voltage stability indices which are found during the literature survey to present reliable information about the closeness of the power system to voltage collapse. The comparison of these indices is presented here and their effectiveness has been tested on various standard IEEE busbar test systems using several different scenarios of load increase. The results of standard IEEE14 busbar test system have been demonstrated specifically. The novelty of the work presented here lies in the method of load increase scenario using a special code written in MATLAB environment. Furthermore, a novel idea of the use of line voltage stability indices to predict voltage collapse within the framework of a voltage security is presented in this paper.","PeriodicalId":131332,"journal":{"name":"2015 5th Nirma University International Conference on Engineering (NUiCONE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127545939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
