Abstract

Rural and remote sites electrification, where national grid is almost impossible because of cost and geographical hurdle, is nowadays an important market for renewable energy based electricity production systems. This paper presents analyzing wind data from 5 masts using Scilab programming software calculating power densities by relative and Weibull density function, and designing hybrid power system for two villages using HOMER software, calculating their installation and operation& maintenance cost. 2(1569808129), Mazin Rejab Khalil, " Design Of an Interruptible Soft Core Processor System to Compute Discrete Cosine Transform of Audio Signals ", Iraq : (8-13). Abstract: Embedded design Techniques are effective tools for configuring a processor system on field programmable gate arrays that can be adapted to function according to the designer target. One of the most outstanding application is to accommodate the embedded designed system to deal with digital signal processing techniques to be used in different practical applications especially in speech and image processing fields.

One of the most outstanding application is to accommodate the embedded designed system to deal with digital signal processing techniques to be used in different practical applications especially in speech and image processing fields. This paper introduces a design of a soft core processor system configured on Spartan 3E field programmable Gate arrays slice using embedded design techniques, the system can process an interrupted audio signal by discrete cosine transform methodology. C language is used to program the soft core processor with enabling its floating point unit. The system performance is consolidated by adding external memories, interrupt controller and a timer to the hard ware part. The system performance is tested and compared with the results achieved by Matlab 10.1 version software 3(1569818855), Hussein Ibzar Zynal; Shawkat Mohammed Younis, " Harmonic Current Reduction of Three-Phase Rectifier Based on Modified Line Injection Technique", Iraq : (14-19). Abstract: This paper presents a modified line injection technique to reduce the input line current harmonics generated by three-phase AC/DC rectifiers. In conventional harmonic current injection method the optimum harmonic current reduction is obtained when (root mean square) (rms) value of the injection third harmonic current equals the DC load current. Therefore the power diode peak current is increased by 72 % compared to without injection case .

The ICECCPCE13-International Conference on Electrical , Communication, Computer, Power, and Control Engineering 17-18 Dec. 2013 In this paper a modified harmonic current injection is applied using a three-bidirectional switches connected to the input lines of the rectifier. The switch that is connected to line with zero current will be turned on to inject the harmonic current to it . In this method optimum harmonic reduction is obtained when the injection third harmonic current equal , one third of the DC load current. Therefore the power diode peak current is increased by 23.5% only and total harmonic distortion (THD) of the input current is less
