Now, the electricity consumers are in a position to demand and expect a higher quality of service. The utilities and power providers have to provide a high quality of service to remain competitive as well as to retain or attract the customers. To achieve this goal an efficient power quality (PQ) monitoring and analysis system is required. This paper presents an S-transform based technique for the detection of power system operational events and power quality disturbances associated with these events. The power quality disturbances associated with the power system operational events such as switching on and off the loads, switching on and off the capacitor banks, tripping and reclosing the transmission lines, outage of the generator and utility network has been investigated effectively. The detailed simulation study of power quality disturbances has been carried out in MATLAB/Simulink environment.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122472327","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}

Low power factor leads to draw extra power from the source to fulfill the same power demand of load. This paper presents a technology named as Magnetic Energy Recovery Switch (MERS) for improving the power factor by compensating reactive power. MERS consists of four semiconductor devices (with antiparallel diodes) connected in full bridge configuration and a DC capacitor. Simulation study is conducted with resistive- Inductive load (to create the reactive power demand) and results are compared with and without MERS, whereas experimental analysis confirms the potential and effectiveness of the proposed technology for power factor improvement.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126655203","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}

Installing only a Proportional controller (P) to control the system, it is observed that there is high overshoot (OS), undershoot (US) and the system takes time to achieve its steady state. The performance of the system relatively improves by installing a conventional PID controller as it decreases the overshoot, undershoot of the system and the system attains steady state faster. The conventional PID controller cannot tackle the nonlinear systems effectively and gives a poor tracking and disturbance rejection performance. In order to further improve the response of the system, Improved Self Tuning Fuzzy (ISTF)-PID controller has been used. In this technique fuzzy logic is used to tune the gains of a PID controller. The various control techniques that are discussed in this paper are designed to achieve the desired D.C. servo motor speed.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125232147","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}

The localization accuracy can be improved by improving the accuracy of estimation of TDOA between sensors. The estimation of TDOA is a challenging task because acoustic signals are corrupted by noise, reverberation, echo and reflection of acoustic signals inside the transformer tank. Keeping this in mind, this paper presents a technique for the accurate estimation of TDOA by extraction of an estimate of the PD pulse from the recorded acoustic signals. The TDOA between two sensors is then calculated by finding the cross-correlation function between the two sensors. The acoustic path through the transformer tank and oil constitutes the physical system, which when excited by the PD pulse, gives rise to the acoustic pressure waves. An estimate of the PD pulse, which generates the acoustic pressure waves, may therefore be obtained by separating the acoustic response of the tank-oil physical system from the acoustic signal. The extracted PD pulse information gives an estimate of the instant of appearance of the PD pulse at each sensor, which makes the accurate estimation of TDOA possible.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124400455","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}

The use of AC circuits in electrical power system has been a common practice nearly since the very inception of the interconnected power network. The most familiar loads on such a system were the constant power, constant impedance and constant current loads or a linear combination of thereof. In these cases, the voltage and current wave forms are nearly sinusoidal. But this is no longer the case with modern electric power system. Enormous use of the non-linear and time varying devices has led to distortion of source voltage and source current waveforms. As a consequence, recently the issue of power quality has become important. Both electric utility and end users of electric power are becoming increasingly concerned about the quality of electric power. The simulation model and results of proposed scheme are described and discussed in this paper.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127842141","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}

Induction motors are used in wide range of applications ranging from fans, pumps, compressors to their use in complex drives for critical application. As the world advances, newer applications come up which require robustness and complete operational control over an induction motor, when subjected to most adverse dynamic real time conditions. These applications need to be controlled using control techniques such as Field Oriented Control, which require the knowledge of induction motor. Use of sensors adds to the cost. If the machine parameters are known, it is possible to eliminate the use such costly hardware speed sensors and replace them with software speed estimators. Scope of this paper is design, simulation and implementation of speed estimation algorithm by estimating the rotor flux angle and slip in a Digital Signal Processor(DSP). The rotor flux angle and estimated speed can be used in sensor-less rotor field oriented control scheme. First, a code is developed for speed estimation of induction motor and is tested in MATLAB. Later, this code is ported to TMS320F28335 floating point DSP and is tested on a 415V, 3.3 HP 1430 RPM squirrel cage induction motor to estimate its speed in real-time.","PeriodicalId":332286,"journal":{"name":"2016 IEEE 7th Power India International Conference (PIICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127757980","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}

Air temperature, earth temperature, relative humidity, daily solar radiation, elevation, latitude, heating degree days, cooling degree days, longitude and atmospheric pressure are used as input variables. Correlation coefficient of 0.99909 is obtained during training and 0.95143 during testing of GRNN model. The proposed GRNN model is then utilized to find wind speed and power potential of major wind power generating sites of Andhra Pradesh, India.

Numerous test cases of internal fault in an ISPST have been using PSCAD/EMTDC software. These cases are formed on the basic variation of different parameters of ISPST like fault inception angle, fault resistance loading condition and percentage of winding.
