Relaxation oscillator based capacitance and resistance measurements are investigated with a compensation technique. Output oscillation frequency of op-amp based relaxation oscillator changes over a range of capacitance variation. The range of capacitance variation considered for measurement is between 57.1 and 206.4 pF. The output oscillation frequency deviates from the theoretical value due to non-idealities of opamp. A compensation technique has been proposed to reduce the oscillation frequency error observed in output waveform. The performance of the op-amp is evaluated again post compensation. The experimental results are compared with an integrator based relaxation oscillator and comparator configuration. Further, the concept of utilizing the compensated relaxation oscillator for resistance measurement has been experimented. The compensated relaxation oscillator provide the improved performance in oscillation frequency of the waveform. Thus, the compensated relaxation oscillator could be employed for both resistive and capacitive sensing for two different measurements such as temperature and moisture measurements.

Every country requires sufficient amount of electricity for their development. In fact, the world needs a renewable, an efficient and sustainable energy production to safeguard our future earth. We documented it, for the people around the world to know about this fascinating technology of young innovative company, Plant-e bringing creative projects to life. It is based on, living plants in Plant-Microbial Fuel Cell (P-MFC) along with bacteria to convert solar energy into in-situ electricity. Plants photosynthesize organic matter for its growth by carbon dioxide, water and thereby capturing solar energy. A significant part of this organic matter is excreted into the soil via the roots as a waste product. In the soil, naturally occurring electrochemically active bacteria break down the organic matter, and produce electrons, which are used for electricity by Plant-e technology. The main advantage of Plant Power is that living plants can capture solar energy naturally and generates electricity 24 hours per day, unlike artificial solar panels. Hence, we can consider it as a “Natural Solar Power.” Plant-e Company also established a business platform for the P-MFC as a promising new bio-energy source and clean technology for applying across the world.

A stable PID controller design can be carried out by properly choosing pole location for desired performance in pole placement approach. Here the control of a plant represented by second order model is carried out by self-tuning adaptive PID (STC-PID) controller based on optimal pole placement design. The pole placement design is carried out by Particle Swarm Optimization (PSO) technique for STC-PID, in conjunction with on-line identification using recursive least square (RLS) parameter estimation method with directional forget factor for an Auto Regression Exogenous (ARX) model. The designed optimal pole placement self-tuning PID (PSO-PP STC-PID) Controller excels in performance to that of fixed-gain optimal PID Controller under parameter variation and random input. The design approach is applied to a case of Hybrid Power Generation System (HPGS) and the performance is presented in a comparative manner.

This paper aims at developing an inexpensive autonomous photovoltaic (PV) array fed irrigation pump utilizing the switched reluctance motor (SRM) drive. A modified Zeta converter is utilized between PV array and motor-pump to incorporate power conditioning. Its continuous conduction mode (CCM) operation helps to reduce the stress on its devices and also the size of PV capacitor. A Perturb and observe (P &O) maximum power point tracking (MPPT) control algorithm is used to maximize the power output of the PV array. DC link voltage is kept variable which allows reduction of sensors. The fundamental switching of mid-point converter improves the efficiency of the system. The suggested system is premeditated in MATLB and further confirmed with hardware implementation. The simulated and hardware results under varying environmental conditions testify the utility and worthiness of proposed system for irrigation pumps.

An autonomous robotic vacuum cleaner, also known as Robovac, performs the task of vacuuming a room autonomously without the need of human supervision. One of the major parts of the working of such a Robovac is its navigation. The Robovac discussed in this paper achieves this task with the help of an array of 4 ultrasonic sensors, which help prevent collisions, and a camera module for computer vision. A caterpillar wheel arrangement, powered by geared dc motors ensures smooth motion over different kinds of surfaces. The hybrid navigation algorithm uses four different algorithms in the same system, namely — Spiral, Wall follower, S-Shaped, and Random Walk, to ensure maximum area coverage in unit time. The proposed algorithm is efficient and simpler as compared to those reported in the earlier literature.

Increased penetration of Electric Vehicle (EV) in the recent past introduces new type of load in the distribution system. Charging of EV may overload the system components, increase voltage deviation and system losses. To analyse the impact of charging of EV on distribution, there is a need of modelling of EV charging load. Currently Constant Power Load (CPL) is considered for the load modelling which does not represent dependency of charging load with the system voltage. In this paper, an accurate load modelling of EV is done considering the charging behaviour of EV. Single stage and multi-stage time variant coefficients of ZIP load model and exponential load model are estimated to model the voltage dependency based on the EV charging characteristics. Estimation problem is formulated as least square minimization problem. Quadratic Programming (QP) and Differential Evolution (DE) is used to solve the estimation problem for ZIP load model and exponential load model respectively.

Researchers have shown that analysis of Time Domain Spectroscopy (TDS) data is an effective tool for condition assessment of oil-paper insulation system. Among various TDS data, Polarization-Depolarization Current (PDC) has gained popularity in recent times. Accuracy of non-invasive technique (like analysis of PDC data) has always been a topic of concern among utilities. This accuracy can be improved by better understanding of dielectric response function as a function of paper-moisture content and aging byproducts. In this research work, a non-linear relation between paper-moisture and some commonly measured insulation sensitive performance parameters is reported. Related analysis presented in the paper show that the proposed relationship, compared to other existing techniques, is capable of providing better accuracy in predicting paper-moisture value. The proposed technique is tested using data collected from several laboratory samples.

Load encroachment function fails to prevent zone 3 maloperation during high reactive loading condition. Such maloperations often causes in cascaded tripping which leads to wide area blackouts. In this work, a group of Phasor Measurement Units (PMUs) are selected to support the distance relay decision during load encroachment. An index D is computed using change in magnitude and phase angle of voltage collected from the selected PMU buses. The negative D depicts a load encroachment and supports the zone 3 decision when apparent impedance enters inside zone 3 characteristic. Performance of proposed method is tested with IEEE 39-bus simulated in EMTDC/PSCAD. Results show the accuracy of the proposed method.

This paper covers the logic of Fast Bus Transfer (FBT) system between three inter-connected switchboards involving three sources. At present, commonly used schemes include a two-breaker scheme and a three-breaker scheme involving maximum two electrical sources or bus-bars. However, fast bus transfer scheme can also be applied to an electrical system involving three sources or bus-bars. Such an electrical system can be adopted to achieve higher level of reliability. The commonly available FBT microprocessors can be used without greatly changing their operating modes and internal microprocessor programming (part of standard product). The focus is on the operating scheme using the existing standard FBT modules with minor modifications.

This manuscript proposes a charger for electric vehicle which operates with both the grid and the solar photovoltaic (SPV) array. The charger is designed to operate in four different modes depending on the exchange of power between the grid, SPV array and the vehicle battery. The vehicle battery is charged by both grid and SPV array. The charger feeds the battery and SPV power to the grid at unity power factor. Similarly, local home loads are powered using the battery and SPV array. The sharing of power between grid and SPV array is decided by the controller and it is designed to use SPV power first and then the remaining power is taken from the other source. While feeding power to the grid, a unit template is used for synchronization. It is designed to operate with a single phase, 230V, 50 Hz AC mains installation. The performance under steady state and dynamic conditions validates the design and control of proposed charger.
