In this paper, six different grades of Assam CTC black tea liquor were discriminated by means of cyclic voltammetry. A 3-electrode configuration was used to study the voltammogram where Polyacrylamide/Exfoliated Graphite composite (PAM/EGC) was used as the working electrode. Data obtained from the tea samples were subjected to multivariate data analysis techniques viz. Radar plot, Box plot and Principal Component Analysis (PCA). The results were found quite promising, thus justifying the suitability of the prepared working electrode for the quality estimation of tea.

This paper deals with inverters which are to be synchronized to share the common load of microgrid. The microgrid under consideration is in OFF grid condition and hence one of the inverters is designed as master and the remaining are designed for slave mode of operation. A state-of-the-art synchronization strategy is developed for the initial synchronization of the inverter during startup period. The microgrid synchronism is then maintained with this master-slave configuration of inverters and the amount of load that can be fed to the microgrid, is adjusted or decided by the user. The control strategy is so designed that the load can always be fed at unity power factor. The SPWM technique and an output filter are utilized to reduce the voltage harmonics to a minimum level and thus produce an almost sinusoidal terminal voltage. The entire design is simulated with MATLAB Simulink and the desired output is achieved.

Phase Rectified Signal Averaging (PRSA) technique is a promising method for analysis of quasi-periodic signals which helps to identify characteristic frequencies contained in the data by disregarding the artifacts and noises. But the performance of the PRSA technique largely depends on the choice of window length (WL). It is required to optimize WL for better detection of precise but important periods present in signal. In this paper a method to optimize the window length is proposed based on the spectral analysis of original and PRSA signal. The proposed method is applied on ECG signal to characterize and classify the atrial fibrillation (AF), atrial flatter (AFL) and ventricular flutter (VFL) rhythms with statistical features. Classification of the fibrillatory episode is done by K-nearest-neighbor (KNN) and support vector machine (SVM) clustering method with derived features. Extracted features are clustered with a new approach of Root Mean Square (RMS) Technique. This algorithm is applied on to the MIT-BIH arrhythmia database and checks the performance. Both quantitative and qualitative analysis is made and sensitivity and specificity 98.24% and 96.08% respectively is achieved.

The Power industry was in demand of a universal global communication standard to enable interoperability and integration between different manufacturers and types of IED, for substation Automation. International Electro-technical Commission (IEC) has developed a global communication standard IEC 61850 to facilitate substation automation. This paper discusses the protocol structure of IEC61850 and researches on the GOOSE messages for interlocking, Ethernet topologies with IEC62850 and SCL. It also elaborates the challenges of migration to IEC61850. Migration to IEC61850 for old substations is a complex and time consuming process, effort has been given to outline a step by step process to introduce IEC61850 into a substation.

In the electricity pricing, the congestion management has become extremely important and it can impose unavoidable problems in electricity trading. In this paper, Gravitational Search Algorithm (GSA) based optimization is performed to address the optimal power flow (OPF) problem governed by contribution factor based ranking and nodal congestion price based ranking in order to achieve congestion relief and maximum economic benefit with desired voltage level and minimum system loss. The methodology has been tested on a typical IEEE test system.

Deregulation of electric power system has brought complexity in the system, competition among the electricity sellers and buyers which further creates overloading in transmission lines. Congestion occurs when undesirable transaction occurs through transmission lines during the transportation of electricity from generation to load centre. It is the duty of Independent System Operator (ISO) to ensure secure, reliable electricity transaction while facing the transmission congestion threat. This article presents a well known congestion management methodology i.e. rescheduling of generator output power in deregulated electricity market. In this work, firstly generator sensitivity factor (GSF) is calculated and based on these GSF values few generators are selected to reschedule their output for congestion management. A new meta-heuristic algorithm i.e. Flower Pollination Algorithm (FPA) has been adopted to reduce the generator rescheduling cost. The proposed work is verified on IEEE 39 bus New England system.

This study focuses on the issue of position tracking of a budgeted electrohydraulic system with the aid of marker based visual sensing of the actuator rod position using a single camera. The system comprises of a single-rod cylinder having non-linear friction characteristics and industry grade proportional valve possessing a large-deadband. A controller has been developed based on an input linearized system model involving the combination of a sliding mode and a deadband controller. An adaptive strategy for the controller parameters relying on a Lyapunov function has been introduced to handle the nonlinearities and uncertainties involved in the system. The controller demonstrated satisfactory performance for the realtime experiments conducted on the laboratory scale system.

Ultrasonic technology is evolving rapidly due to the significant improvements of the flow measurement in continuous industrial process. It is a widely used technology among the non-contact type of flow measurement for its high resolution, low pressure loss, less interference of noise on output. Ultrasonic flowmeters gained the debate, mainly due to measurement ability in custody transfer of natural gas, accurate measurement of the flow of slurries and impurity liquids, works for wide range of nominal diameters. This paper contains review on some important developments of transit time ultrasonic flowmeters particularly to improve the accuracy.

The main objective of this paper is to estimate the states (i.e. voltage magnitude and angle δ) of the buses in a radial distribution network with the help of a Phasor Measurement Unit (PMU) placed at the sending end (SE). The remote bus parameters are estimated using the samples of voltage and current signals only of the local bus end where a PMU is placed. The estimated parameters are verified with the standard load flow techniques. The verification of results proves its utilization for online load flow analysis and the reduction of the number of PMUs to one. Hence the requirement of multiple PMUs at the different buses and their associated communication systems is no longer required.

Wide area measurement is significant for modernized control of power system. Phasor measurement unit (PMU) being the prime element for wide area measurement system (WAMS), it provides proper feedback to the closed looped controller to take proper steps during power system transients. This paper aims to measure the state of six bus power system in off-nominal frequency condition. To achieve this firstly a three phase PMU is simulated using recursive algorithm and then the algorithm is made frequency adaptive by re-sampling. Pseudo measurement using ABCD parameter is also proposed and implemented.
