Abstract

As the utilization of wind energy grows larger and larger, the need for technical improvement and theoretical understanding becomes significant. Wind energy has been used for many years, however the central questions regarding turbulence are still to be answered. In this complex situation, it is important to analyze the phenomena involved in wind energy extraction. This work presented a stochastic analysis of the power output for a wind turbine based on a Monte Carlo simulation to see how fluctuations in the wind speed will affect the power performance characteristics. It is shown in the presented work by means of a simple model that the probability of power characteristics determined varies with different turbulent wind fields. Then this model is applied on an IEEE 9 bus network.

Abstract

Network reconfiguration is an operation strategy, which alters the topological structure of the distribution feeders by rearranging the status of switches in order to obtain an optimal configuration, minimise system losses, improve voltage profile, and reliability. In this paper, Loss Sensitivity Factor based Network Reconfiguration Algorithm is proposed to decide the switching combinations and to find the best combination of switches for minimum active power loss, improvement of voltage profile, and reliability. The proposed algorithm has been applied to 33-bus Radial Distribution System and the obtained results are analysed.

Abstract

This paper presents a comprehensive study on the performance of Shunt Active Harmonic Filter (SAHF) for harmonic compensation, where Ant Colony Optimization technique is used for optimization purpose. This optimization technique operates for the optimal PI control parameters which regulate the DC link voltage. Instantaneous real and reactive power (p-q) theory is used for calculating compensating currents. The simulation results show that Shunt Active Harmonic Filter (SAHF) for six pulse controlled rectifier proves to be very effective in mitigation of the harmonics present for various firing angles. The simulation is carried out with the help of MATLAB-SIMULINK tool box.

Abstract

In the present circumstances, industries are highly increasing and demanding process in all sectors. Permanent Magnet Synchronous Motor gives better results in quality, increased production, and reduced costs. Permanent Magnet Synchronous Motor (PMSM) drive plays a vital role in each and every industry. There is a necessity to upgrade the models of the electric motors and drives for a better simulation. This paper introduces the design and evolution of a simulation platform of PM Synchronous Motor drive. This paper provides advanced modeling and Matlab simulation tools for PM Synchronous Motor drive to designers and the developers of electric motor drive control systems allowing them to model the independent components using the appropriate software. This paper shows the methodology to interface PMSM Motor on a single simulation platform. In this work, the electric machine model is developed using MATLAB software. Whereas the power electronic converter and PMSM drive control models are designed using mathematical equations in MATLAB/SIMULINK.

Abstract

In this paper, a mathematical model of PMSM is analysed using the dominant simulation modelling capabilities of MATLAB/SIMULINK. One of the most efficient control strategies of PMSM is Vector control. There are several independent functional module, such as coordinate transformation module, PMSM body module, inverter module, controller modules, and some other modules which play an important role in controlling of PMSM. The combination of these modules results in simulation model of the PMSM control system. The model has many advantages in simulation. The detailed structure of the simulation model in MATLAB/SIMULINK is presented. Finally, a simulation example is proposed to verify the feasibility.

Abstract

Flexible AC Transmission System (FACTS) controllers control the power flowing through transmission lines to improve utilization of power system, transmission loop flow control, reliability and relieve congestion. High cost, reliability and land restriction issues have limited their use in the power system. The Distributed-FACTS (D-FACTS) controller is presented as a new approach to recognize economic power flow control through compound, small, fixed series impedance injections. A new device which is distributed version of Thyristor Controlled Series Capacitor (TCSC) controller, Enhanced Power Flow Controller (EPFC), connects directly to the existing high voltage or extra high voltage lines. It can be manufactured at a lower price than FACTS controllers from conventional low-grade components. This EPFC is distributed over whole transmission line as modules at every short span of length of transmission lines to attain the required power flow control functionality by changing the transmission line reactance dynamically or statically. It uses the concept of DFACTS to control the power flow. The results from an EPFC MATLAB/Simulink model are presented in this paper on a transmission system which is connected with EPFC controller modules.
