Permanent magnet synchronous motors (PMSMs) have dominated the motion control industry to the present, and, according to the current trend, there seems to be no end for it Induction motors have always been a minority in the motion control, and they are mainly used in applications, where the field weakening can be utilized to avoid the over-sizing of the drive, which would be the case with PMSMs. There is an increasing trend of using Space vector pulse width modulation (SVPWM) because of their easier digital realization and better dc bus utilization. In this paper both Sinusoidal PWM and space vector PWM feeding a PMSM motor are considered. These techniques are studied through simulation using MATLAB/SIMULINK software and the performance of both the techniques are compared. It is shown through simulation that Space vector PWM effectively utilize dc line voltage and generates reduced THD when compared with Sinusoidal PWM.

Planned application of Distributed Generation (DG) in distribution system can provide voltage support at feeder and help to avoid branch overloading, network power loss, high investment cost etc. A Particle Swarm Optimization based formulation of constrained optimization problem to facilitate determination of sizes of multiple DGs has been proposed in this paper. Both the minimum and maximum sizes of DG units are evaluated for a certain range of voltage level of buses. Proposed methodology can ensure an appropriate level of voltage enhancement of network. A novel voltage stability factor of equivalent two bus system of the whole network has been proposed which can measure the proximity of operating state of the system to the point of voltage collapse. The effectiveness of the proposed methodology has been tested on 15 bus and 33 bus radial distribution systems.

This paper presents the speed monitoring of a DC motor drive using field programmable gate array which provides a faster operation than any other conventional analog methods or digital methods like DSP. The paper consists of two parts. The first part deals with the MATLAB simulation for speed control of a DC motor using fuzzy logic. The most effective method of control is the control of PWM, generated for triggering the converter circuit. The PWM is given through the driver circuit to the half bridge converter, which controls the speed of the motor. The hardware part deals with the speed monitoring of the DC motor using FPGA. In this implementation, the PWM is generated using XBLINX software, which is given to the converter through the FPGA The use of FPGA reduces the processing speed and hence increases the efficiency of the motor. The result of the open loop control is compared with the fuzzy logic control.

This paper presents Biogeography Based Optimization or BBO technique to determine short term hydrothermal scheduling, taking into account most of the equality and inequality operating constraints. Biogeography deals with the geographical distribution of biological species. Mathematical models of biogeography describe how a species arises, migrates from one habitat to another and gets wiped out The proposed algorithm has been found to perform better in terms of computational time and minimum fuel cost, due to which this method seems to be a promising alternative approach for solving the hydrothermal scheduling problems in practical power system.

A Z-source inverter with a customized modified reference (sine) based pulse width modulation technique is proposed for energy conversion systems. In this system six reference waves and one carrier wave is used to generate switching pulses. The purpose of this paper is to demonstrate that the Z-source inverter will boost the AC voltage whenever required, and perform minimum output distortion with maximum tracking and interface it with the renewable energy system. The control method is analysed with simulation and experimental results. Also the control method is implemented in DSC (TMS320F28335).

This paper presents a novel methodology for optimal placement of Distributed Generation (DG) in an Optimal Power Flow (OPF) based wholesale electricity market. DG is placed in real time wholesale electricity market. The problem of optimal placement including size is formulated for two different objectives, namely, fuel cost reduction and to provide voltage stability at distribution level. DG reduces the cost of electricity to the costumer, relieve network congestion and provide environmental friendly energy close to load centers. The candidate locations for DG placement are identified on the basis of locational marginal price (LMP). OPF is widely used for both the operation and planning of a power system. The key feature of standardization of restructured power market like Standard Market Design (SMD) is the LMP scheme. OPF problem by placing DG in Deregulated Environment is solved using Genetic Algorithm (GA). The proposed methodology is tested with IEEE 30 bus test system.

Renewable energy can be used to decrease global dependence on natural resources, and tidal power can be the primary form of renewable power utilized. Built upon steam turbine knowledge, tidal turbines draw on innovative technology and design to operate on both the inflow and outflow of water through them. Tidal power utilizes twice the daily variation in sea level caused primarily by the gravitational effect of the Moon and, to a lesser extent by the Sun on the world's oceans. The Earth's rotation is also a factor in the production of tides. Control & Operation system for tidal power plant should be simple, reliable, cheap and with minimum interference of operating personal. Control system should be such that remote operation can be performed easily. The main functions of the controller for automation is to execute starting and the shut down sequences under normal and emergency conditions. In this paper an attempt has been made to elaborate the use of Programmable Logic Controller (PLC) for control and automation of tidal power plant, its advantages and cost effectiveness. Programmable logic controllers (PLC) can be used for control & automation of tidal power plant. The main reason for this is cost effectiveness. Various functions and controls can be achieved by programming the PLC. They can be used for full plant automation including governing of auto-operation includes speed control, load control, excitation control, and level control automatic start/stop sequencing, barrage gate control, start/stop of auxiliary systems, and protection requirement etc. Functions other than control like continuous monitoring, data recording, instrumentation and protections can also be performed. For remote operation, communication with PLC can be performed. For continuous monitoring purpose, a personal computer can be interfaced with PLC and continuous data can be recorded regularly [16].

In this paper, an electric vehicle drive using alternating current (AC) induction motor with low cost and robust construction is presented. This approach is applied to an already existing commercial utility electric vehicle where previously used direct current (DC) series motor was replaced by the new AC induction motor. A voltage source inverter is used for three-phase squirrel cage induction motor which requires supply of DC voltage from vehicle battery system. A new DSP based voltage inverter is designed for the proposed drive. The used processor realizes the field oriented control algorithm with torque and flux closed loop control. The processor computes the motor speed using speed observer. In this paper system description, control algorithms realization, and speed computation are presented. The paper also includes the simulation and experimental results of the discussed system The proposed drive does not have a speed sensor, which make the solution sensorless which reduces the cost and is reliable on speed sensor faults.

The distribution static compensator (DSTATCOM) is used for enhancement of power quality in power distribution network with unbalanced, nonlinear and variable loads. The dc link capacitor voltage is directly affected by any alteration made in the load. The sudden decrease of load would result in an increase in the converter dc link voltage above the reference value, where as a sudden increase in the load would reduce the dc link capacitor voltage below its reference value. For proper operation of DSTATCOM requires variation of the DC link capacitor voltage within the prescribed limits. Right from the beginning, a proportional integral (PI) controller has been used to maintain the converter dc-link capacitor voltage to the reference value. Despite of it, the transient response of the conventional PI controller is still slow. In this paper, a fast acting dc-link voltage controller based on energy of the converter dc-link capacitor is proposed. Reference current is generated based on instantaneous symmetrical component theory for improving power quality in the power distribution network. Mathematical expressions are given to design the fast-acting dc-link controllers to achieve the fast transient response. A simulation study of the proposed method has been carried out using MATLAB simulation software.
