The calculation of the Coefficient of Voltage Non-sinusiadility on the Bus of Substation is a significant issue. We have presented the results of the local electrical distribution system of a company in this paper. We have also performed the experimental results. We have assessed the reasons for the determining the damages and proposed many solutions to fix the technical as well as the economic decisions for the issues. Read More Read Less

Abstract In this work we have analysed the energy contribution of the major water basin and studied how the hydro power plants of the cascade on hydroenergy system works.

In this work we have analysed the energy contribution of the major water basin and studied how the hydro power plants of the cascade on hydroenergy system works. The studied hydro energy system consists of two cascade hydro power plants and three reservoirs, but the operation experiences and the site location give the possibility to upgrade the system with additional hydro power plants. We did the technical calculations and power improvement are the base platform to make the economical evaluation of the NPV, B/C, PBP values for each power plant from all over integrated hydro energy system. The geographical configuration of the terrain and hydrological conditions of the region, especially the tributaries of the studied river, and allow construction of more hydropower plants. These hydro power plants would improve the energy situation, and also would regulate the operating mode of existing HPP. This study analyzed more the hydropower projects in the studied basin which are analyzed and planned for long time. The testing data is presented in the paper which are the energy production and economic viability of the construction and operation in power system. Read More Read Less

Abstract We have presented a mathematical model of the aircraft system for automatic guidance for landing using GPS –GBAS. Further we performed the simulations for landing guidance system when using the ILS and GPS – GBAS. To do the simulations, the programming package MATLAB/SIMULINK is used. In the current work, a, comparative analysis of the results of the simulations and the...
