Fractional KW electrical machines used in domestic and industrial applications are mostly asymmetrical two phase induction motor supplied by single phase supply. Though many techniques are available for control of three phase induction machine for extracting its best performance, but no such generalized technique is available for controlling Single Phase Induction Motor (SPIM). In this paper, a SPIM is studied, where a dynamic capacitor is used for obtaining maximum torque operation. The SPIM makes use of indirect current control of Voltage Source Inverter (VSI) with a capacitor on its DC bus, so that it can work as a variable capacitor. Then a maximum torque operation is obtained, by connecting this dynamic capacitor in series with the auxiliary winding, and is controlled in such a way to keep the main and auxiliary winding currents in phase quadrature to each other. And along with dynamic capacitor a dynamic model is developed in stator reference frame (d-q). For proposed configuration, performance of the SPIM is studied using MATLAB, to demonstrate the effectiveness of the dynamic capacitor.

Proportional - Integral - Derivative (PID) controller performs well for linear systems. For systems with nonlinearity, controller parameters need to be tuned every time for new operating point to obtain `local gain parameters'. These local gain parameters are not sufficient to get satisfactory performance at other operating points. In this paper a novel approach `Aggregate Fitness Function' is presented to obtain the `global gain parameters' that works satisfactorily at various operating points. Online optimization scheme with Genetic Algorithm (GA) is adopted to tune the Proportional-Integral (PI) controller parameters for setpoint tracking of DC Motor by minimizing Integral-Time-Absolute-Error (ITAE). Hardware validation of the results is presented and studied. The plant under study is DC Motor Control Module (MS15) from M/S LJ CREATE™. M/S National Instrument (NI) based software and hardware components i.e. LabVIEW™ and its add-ons toolkit and Data Acquisition (DAQ) Card has been utilized for online tuning and closed loop run time control. The simulation and run time results clearly show the efficiency of the proposed approach.

This paper deals with a three phase single-stage multitasking grid tied SECS (Solar Energy Conversion system). A single three leg VSC (voltage Source Converter) topology is used in this work. The SECS not only feeds solar PV (PhotoVoltaic) energy into the grid but also serves the purpose of grid currents balancing, reactive power compensation, harmonics elimination and MPPT (Maximum Power Point Tracking). A feed-forward term for the solar contribution is used to improve the dynamic response for climatic changes. The PV array voltage and hence the dc link voltage is continuously adjusted to achieve MPPT. A RAD (Round Adaptive Detection) based algorithm is proposed for the control of three phase VSC. The system is modeled and simulated on MATLAB based platform. A wide range of simulation results are shown to demonstrate all features of proposed system. Moreover, all salient intermediate control signals are provided for assessment of control algorithm. The THD (Total Harmonics Distortion) of grid current has been found well under IEEE-519 standard.

This paper proposes an assessment of the operational parameters of a thermal power plant to promote effectively & efficient running of the machine while ensuring a degree of compliance with statutory regulations. This study aims to identify the operational gaps associated with running operational parameter in power plant process. It is focused to detect a different thermodynamic variable involved, being multivariate and automatic. For variation of each one of this operational parameters, performance calculations are carried out to configure a database of energy variation. The variable data sets now can be used as assessment criteria based on detecting deviations from a reference system that has been updated during plant-performance tests. Although the most important outcome is the highly precise and valuable information that will be obtained on the live operating mode, leading to ahead improvements in the cycle efficiency and achieved in the overall control system of the thermal plant. The main aim is to detect any abnormality, reacting as quickly as possible to return the plant to a normal operation mode at best efficient manner.

In regulated electricity markets, there is trading of large volume of power over existing transmissions lines. Due to this, some corridors experience congestion and may endanger system security, stability and reliability. To overcome this, Unified Power Flow Controller (UPFC) can act as a decongestion device and can improve power flow. The proposed method uses a modified gravitational search algorithm to improve maximum power transfer capability of UPFC. This is tested on IEEE-57 bus system.

In this paper, modified Schneider operator and modified AL-SKG rule based recursive digital differentiators have been analyzed in the low frequency range. The first order s-to-z transformations obtained are in close conformity to the ideal differentiator in terms of magnitude. The phase response shows a linear variation in this range which is also desirable for several applications. MATLAB simulation results are presented to validate the effectiveness of the proposed analysis. These models can be used for discrete realizations of low frequency differentiators.

Lakshadweep Island is one of the union territory of India. The main source of electricity in Lakshadweep Island is diesel generators, the diesel being transported from the main land. Due to high energy costs, the islands are proving to be excellent test beds for the introduction of new technologies, and becoming so-called renewable energy islands to satisfy their energy demand mainly from indigenous and renewable energy sources. With its fragile locations, geographical and environmental limitations it is desirable to explore possible strategies to utilize maximum available potential of non-polluting renewable energy sources for this ecologically sensitive island. This paper examines the penetration of renewable energy sources in general and dissemination of solar photo voltaic (SPV) based power generation of electricity in particular for balance solution to the energy problems of Lakshadweep Island using technology diffusion models. It was found that with different diffusion models, the future time frame of SPV based power generation is likely to reach its maximum estimated potential in another 40 years.

VANETs (vehicular ad hoc networks) are distributed, self-organized and potentially highly mobile networks of vehicles communicating via wireless media. They are a form of Mobile Ad hoc Network (MANET) where movement of each node (vehicle) is restricted by road direction, encompassing traffic and traffic regulations. The different challenges in VANET such as intermittent connectivity, abrupt changes in network topology and low reception rate distinguish it from other types of ad hoc networks. This paper covers different performance metrics encountered in recent literature, for small and large scale broadcasting protocols. Novel ideas are needed to optimize reliability and time criticality metrics in data communication protocols for VANET. The reason for analyzing the broadcasting protocols is that, in most of the emergency situations, there is less time to make a handshake with other nodes in the networks, as the emergency message is to be delivered fast and efficient. Therefore broadcast based routing protocol plays a major role in almost all the safety applications. A detailed understanding of the existing protocol is needed before contributing new protocol for the upcoming research field.
