Abstract

Compact fluorescent lamps (CFLs) are increasingly being used in households and commercial buildings because of the desire to reduce electricity usage. CFLs are nonlinear, which raises concerns over the widespread use of CFLs due to possible adverse effects on harmonic voltage levels in the distribution system. A MAT LAB model of a simple CFL ballast circuit is shown to match actual CFL current waveforms and is used to assess the interactions between multiple CFLs connected to an electrical network. This work shows the error of using fixed harmonic current injection to model CFLs in a distribution system. Finally, the concept of CFL tensor analysis with phase dependency is introduced.

Abstract

In this paper a new robust load frequency controller for two area interconnected power system is presented to quench the deviations in frequency and tie line power due to different load disturbances. The dynamic model of the interconnected power system is developed with new state variables without the integral and area control error. The frequency deviations and their derivatives are zero under steady state operation before and after the disturbance. The two area inter connected power system is subjected to a wide range of load disturbances and switching times. To validate the effectiveness of the proposed Fuzzy controller over the Proportional pulse Integral pulse Differential (PID) controller, Optimal controller and Genetic algorithm controller is compared. The results prove that the transient performance with the fuzzy controller placed in both the areas is better than those obtained by the other controllers. The problem is also solved by switching the controllers with certain time delay.

Abstract

This paper presents a control method for hybrid active power filter using Space Vector Pulse Width Modulation (SVPWM). In the proposed control method, the Active Power Filter (APF) reference voltage vector is generated instead of the reference current, and the desired APF output voltage is generated by SVPWM. A MATLAB code is developed to generate the SVPWM switching pulses fed to the two-level inverter topology. The entire power system block set model of the proposed scheme has been developed in MATLAB environment. The developed control algorithm is simple. The APF based on the proposed method can eliminate harmonics, compensate reactive power and balance load asymmetry. Simulation results show the feasibility of the APF with the proposed control method.

Abstract

Adjustable speed drive system requires variable voltage and frequency supply which is invariably obtained form a threephase voltage source inverter. A number of pulse width modulation schemes are used to obtain variable voltage and frequency supply form an inverter. The most widely used PWM schemes for a three phase VSI are carrier based sinusoidal PWM (SPWM) and space vector PWM (SVPWM). There is an increasing trend of using space vector PWM because of their easier digital realization and better dc bus utilization. The MATLAB/SIMULINK simulation results show the superiority of the SVPWM compared to SPWM for an adjustable induction motor drive.

Abstract

In the present work power system transient disturbances using Stockwell and Hartley Stockwell transforms have been identified. Stockwell transform (ST) is utilized previously for the real time prediction of the disturbance as it is able to accurately determine the sudden burst in the signal. However, in some cases the frequency resolution of ST is low. Consequently, Hartley Stockwell transform (HST) has been proposed which has a good frequency resolution. A comparison of proposed HST technique with ST considering various test cases has been carried out, which shows its efficacy.

Abstract

With the development of technology, electrical automation is coming up as an optimal solution for monitoring and auditing of power consumptions. In conventional approach of power monitoring, manual readings and monitoring for the forecasting of load dispatching and consumption were made. In such an approach the error of processing is quite large. In this paper, automation of monitoring and load consumption using wireless GPRS based communication system is proposed. The designing and modeling of measuring and monitoring unit is also proposed. The developed system is tested for its feasibility over a real time distribution system and the results were evaluated.

Abstract

An improved DTC scheme based on space vector modulation (SVM) for Permanent Magnet SynchronousMachine(PMSM) drives. The new scheme provides a alternative option for the improvement of DTC controlled PMSM in reducing the torque ripple. Closed-loop control of both torque and flux is developed with proportional Integral controllers. The stator voltage vector is generated through Space Vector Modulation unit. The torque and flux ripples are greatly reduced with space vector modulation technique comparing with classical switching-table based DTC scheme. The analysis of the control principle provides a guide to design the controller parameters. Modeling results present the features effectiveness of the proposed scheme.
