This paper presents on-line efficient detection and adaption of rotor resistance in the Indirect Vector control of induction motor. As the rotor resistance variations occur during the normal running condition of motor, it can cause performance deterioration unless it is detected and compensated. In this paper a novel approach for rotor resistance determination is proposed directly from decoupled stator voltage and currents and the response of speed, torque and currents are examined by including rotor resistance variations. The proposed method in the paper will definitely overcome the problems related to rotor resistance variations and improves the performance of Vector control.

A new Algorithm to locate fault on a three phase transmission line is proposed in this paper. To locate fault on any point on the transmission line, the proposed method first measures synchronized voltage and current from both line terminals. The positive sequence components of the pre-fault and the post-fault phasors, positive sequence source impedances at both terminals are also calculated. Using these source impedances and the line data, the positive sequence bus impedance matrix (Zbus) is formed. Fault location is obtained by using impedance matrix. This algorithm is tested extensively with data obtained from the MATLAB simulation of a long transmission line simulated with distributed parameters in the presence of fault resistance and fault inception angle. The simulation results show that the method is quite accurate and robust.

Among the different disturbances affecting the power quality, the voltage sag are considered as a most important power quality problem faced by utilities, industrial consumer & equipment like PLC (Programmable Logic Controller), ASD (Adjustable Speed Drives) which need to be fully investigated. Custom power device are effective means for mitigating the voltage related issues prominently voltage sag, unbalanced load voltage, voltage regulation, sag/ swell etc. by compensating the reactive power with the injection of shunt current. Various DSTATCOM topologies & control scheme are suggested in the literature. In this paper by using three level H-bridge topology & five level cascaded multilevel inverter based DSTATCOM the voltage sag is compensated effectively with reduced total harmonic distortion (THD).

In the recent years, world has witnessed continuous growth of ICT services and global information society. According to ITU, the single most dynamic ICT development over the recent years has been the surge in the mobile broadband subscriptions which has emerged as one of the major sources of world energy consumption and is expected to get more demanding in the future due to increase in the density of base stations in 4G and beyond wireless communication networks. The transition towards renewable energy sources (RES) can sustain this high energy consumption. In this paper, we have discussed the need of energy optimization in wireless communication network through various renewable energy sources which can be Fuel Cell, Solar and Wind, Pico Hydro, and Biodiesel.

In this paper, two different PID control methods are described to control of Maglev Guiding System for Linear Elevator. The linear elevator driven by permanent magnet linear synchronous motor (PMLSM) use the method to adopt the magnetic guidance system to control the PMLSM gap which changes frequently and can impact the vertical thrust and control the level vibration and noise in the process of start, operation, and stop to make passenger feel comfortable. The first PID control method is based on feedback linearization. In this method, single Maglev guiding systems are controlled to maintain the air gap of linear motor in the reference value independently. To achieve a more practical control method and better operation of maglev guiding system, this method is corrected and a simultaneous control method of two counterpart Maglev systems is proposed. MATLAB modeling of these systems are used in this paper. Simulation results show that the second method has a better performance.

The paper advocates in association with a new simple hybrid analysis and design of the protection schemes of the switch mode power supply. Basically, there are two parts of analysis and design, one is the simple Resistance and Capacitance (RC with small inductor) snubber circuit with over voltage protection and other is short circuiting-overload protection. The quasi-empirically designed components and devices of the snubber network also curtail the substantial stress across the switch during both turn-on and turn-off. It suppresses the ringing to safe amplitude of gate pulse in the switch. A simple scheme also describes here that protects not only the power supply due to excessive load drawal and stress across the switch by the load but also easy to implement at low cost and light weight to any generic power converter topologies due to optimization of high frequency switching. This unique snubber also lessens the switching losses and electromagnetic interference, by virtue of which nine to ten percent efficiency attainment is feasible of the converter.

The conventional method are iterative and bulky in nature for power flow measurement of a system. The Phasor Measurement Unit is a new technique for measurement of bus voltage and power flow. The concept of full weighted least square state estimator is nonlinear in nature, but with conventional method and PMUs it will improves the accuracy of the measurement without using the iteration process. In this paper the way of formation of measurement by using conventional method incorporation with Full weighted least square state estimation and PMU use will be investigated. Some cases are tested by introducing of PMUs and the effect on variables accuracy due to PMU on bus voltage and power flows are illustrated. The comparison of parameter obtained on IEEE 6 and IEEE 9 bus system will be discussed.

In recent years generation of electricity using wind power has received considerable attention worldwide. Induction machines are mostly used as generators in wind power based generations, since induction machines have a stability problem as they draw heavy reactive power. To improve stability of the system reactive power compensation is provided. In the literature various methods have been already suggested for improving the reactive power using different controllers. This paper deals with voltage stability improvement of a distribution system embedded with Wind Turbine Induction Generator (WTIG) by using power electronics based Flexible AC Transmission Systems (FACTS) based Distribution Static Compensator (DSTATCOM). The behavior of the system during the load condition is investigated. The study is carried out by three-phase dynamic simulation of distribution system component models. Simulation are presented for different cases such as with and without capacitors and also for with and without Distribution Static Compensator (DSTATCOM). The simulation analysis of voltage stability and reactive power compensation of distributed system with Wind Turbine Induction Generator (WTIG) is performed using MATLAB/SIMULINK.

Power quality problems have received increasing attentions in recent years due to proliferation of nonlinear and sensitive loads as well as unpredictable and unavoidable system faults. Power quality problems mainly include current and voltage harmonics, reactive power, supply unbalance, sag, swell etc. Series Hybrid Active Power Filters (SHAPF) have been the main topic of interest for researchers working in the area of active power filters (APF). SHAPF provides cost-effective solution as compared to standalone active filters and are preferred to compensate both voltage and current type harmonics. This paper present simplified control strategy for SHAPF with added functionality of compensating voltage sag, swell and unbalance. Mathematical formulation of reference generation scheme with simulation verification of SHAPF model is tested for compensation of voltage sag, swell, unbalance and harmonics is presented.
