This paper explains different converter topologies with different induction generators used for wind energy conversion system. In this focused area of renewable energy resources, wind energy conversion system is more popular than the other conversion systems. Four main types of induction generator used in wind energy conversion system (WECS) are Squirrel Cage Induction Generator (SCIG), Permanent Magnet Synchronous Generator (PMSG), Doubly Fed Induction Generator (DFIG), and Wound Field Synchronous Generator (WFSG). Presently, Doubly-Fed Induction Generator (DFIG) is widely employed in modern wind power industries. The maximum electrical power can be obtained in both wind speeds of above and below synchronous speed using DFIG. Also, it reduces the power rating of the converter. This paper mainly explains the study concepts of Power converter topologies used with Doubly Fed Induction Generator (DFIG) connected wind energy conversion system.
This paper deals with Single Phase Five level Inverter using Multi Carrier Based Pulse Width Modulation Technique. The voltage quality of conventional two level inverter is poor due to the presence of harmonics and hence produces power loss which reduces the efficiency of the system. The multilevel inverter is used to improve the voltage quality by reducing the harmonics. As the number of voltage levels of multilevel inverter is increased, the harmonics are reduced and hence losses are minimized significantly. The simulation of single phase cascaded five level multilevel is done using Multicarrier PWM technique and compared with sine wave. Here the authors compared conventional PD and variable PD and simulated outputs were given.
A system is a collection of components arranged to a specific design in order to achieve desired functions with acceptable performance and reliability. Reliability engineers often need to work with systems having elements connected in series and parallel, and to calculate their reliability. To this end, when a system consist of combination of series and parallel segments, engineers often apply very convoluted block reliability formulae and use software calculation packages. As the underlying statistical theory behind the formulae is not always well understood, errors or misapplications may occur. In this paper, exponentially distributed failure rate of the components will be considered for unit or component redundancies and evaluation of basic probability indices for various system configurations like series parallel, series-parallel, parallel-series configurations and complex systems have been dealt with deriving generalized expressions for ‘n’ component repairable systems. A computer program has been developed to apply generalized expressions for various systems. Application of the derived formulae is used to obtain basic probability indices of load point and for the Power System network.
This paper presents a simple algorithm for the Static State Estimation of a Power System. The proposed algorithm makes use of the Weighted Least Square Estimation techniques to estimate the Static State of Power System and hence to analyse the observability of the power system network. Concept of Chi-square test is used to detect the presence of bad measurements in the available data. Developed algorithm is demonstrated for sample 2 bus system.
In this paper, non-dominated sorting genetic algorithm-II(NSGA-II) is proposed for optimal placement of hybrid, i.e. PMUs and conventional meters. The hybrid measurement placement problem has been solved by simultaneously optimizing the two conflicting objectives, viz, Maximizing the measurement redundancy and the other, minimizing the installation cost ensuring full network observability. The Pareto optimal solutions are obtained using the non-dominated sorting and crowding distance criterion. Subsequently, a decision making procedure based on VIKOR method is employed to determine the best conciliation solution from the set of Pareto-optimal front. The effectiveness and flexibility of the proposed algorithm has been tested on IEEE 14-bus, IEEE-30 bus, and IEEE 57-bus systems respectively
