IIJ01 : Impedance Insertion Islanding Detection Technique for Grid Connected Micro-grid System

AUTHORS: G. R Dange, Dr. V. K. Jain

ABSTRACT : In a grid integrated DG system, when utility system fails to supply, distributed generation (DG) continues to supply the local load this is the condition of islanding. In this paper a passive islanding detection technique using impedance insertion method is proposed for fast detection of islanding event. The scope of research is to protect the system against any voltage transients when sudden switching of high power transient is occurred.

Index Terms— Distributed energy Resources (DERs), Renewable Energy Sources (RES), islanding detection techniques (IDT), Remote method, Local methods.

IIJ 02 : Modulation Techniques for multilevel inverter; A review

AUTHORS: Prachi Tiwari, Dr. V. K. Jain

ABSTRACT: In numerous modern applications, the output voltage of inverters must be controlled to beat the adjustments in input voltage and to meet the need of voltage/current control. Clearly sounds in the yield voltage rely upon the chose PWM. Utilizing more number of semiconductor devices and switching redundancies, bring a larger amount of complexity in the nature of multilevel topologies, when contrasted with a two level inverter this paper presents the comprehensive overview on numerous modulation technique available in literature to obtain the desired output from multilevel inverter.

Index Terms—Multi level inverter (MLI), Pulse width modulation (PWM), Space Vector Modulation (SVM), Space Vector Control (SVC), Selective Harmonic Elimination (SHE).

IIJ03: A DETAILED SURVEY OF FLOATING COLUMNS IN A REINFORCED CONCRETE BUILDING

AUTHORS: Dharmendra Kumar Yadav, Prof  Jatin Mehta

ABSTRACT: Reinforced concrete (RC) is a versatile composite and one of the most widely used materials in modern construction. Concrete is a relatively brittle material that is strong under compression but less so in tension. Plain, unreinforced concrete is unsuitable for many structures as it is relatively poor at withstanding stresses induced by vibrations, wind loading, and so on. To increase its overall strength, steel rods, wires, mesh or cables can be embedded in concrete before it sets. This reinforcement, often known as rebar, resists tensile forces.

IIJ04: A review of novel control strategy for grid synergistic single-phase solar rooftop PV system using generalized integrated theory and experimental results

AUTHORS: Suryakant Upadhyay, Sagar Tomar

ABSTRACT:  A novel control strategy presents for rooftop PV system. Where boost converter is controlled by MPPT algorithm and single-phase inverter is controlled by unit template with second order generalized instigator. The Maximum Power Point Tracking Controller (MPPT) is an essential part of the photovoltaic (PV) system, it is used to extract the maximum power from the photovoltaic solar module and transfer that power to the load. Several MPPT techniques have been proposed in the literature. One of the most commonly used techniques is the perturb and observe algorithm (P&O), due to its low cost and simple implementation, but it suffers from the slow tracking speed for small step of perturbation and oscillations around the maximum power point (MPP) when it is subjected to a large step. In this thesis, the P&O algorithm with a variable step size (VS_P&O) is simulated by the PSIM software, analyzed and compared with the fixed step size P&O technique (FS_P&O). These two techniques are also simulated with and without proportional integrator corrector (PI corrector). The results show the good tracking, the high efficiency and precision of the VS_P&O technique using the PI corrector.
