Abstract

In high voltage AC system, the system voltage and frequency change rapidly with the variation of load. The reactive power also changes with the variation of load which affects the system voltage therefore it is necessary to analyze the power system in order to determine system parameters and its variation under various load conditions. The capacitor bank size is determined by calculating existing reactive power and required reactive power in system for Static VAR Compensator (SVC) is focused in this paper. Base case load flow is used to analysis power system. After identifying low voltage buses, arbitrary caciptor back is imposed in bueses and results are checked whether it is met or not in the system demand level. Here MATLAB coding is used to find the low voltage affected bus and automated calculation of capacitor back size is done by MATLAB also. The proposed method of identification of low voltage buses and determination of capacitor bank are faster and easier than the conventional method.DOI:http://dx.doi.org/10.11591/ijece.v4i4.5803

Abstract

Due to less pollution, silence and high efficiency electric vehicles are fascinating to the citizens widely. There are number of physical and electrical aspects are to be considered during vehicle modeling. When electric vehicle runs on the concrete surface rolling resistance resist the vehicle tire to move fast. On the other hand when the vertical angle of vehicle drive is increased or decreased by somewhat degrees the forward force is also increased or decreased respectively. In this paper, a typical electric vehicle dynamic is modeled to mechanical parameter after conversion its mechanical torques, the electrical power is obtained by required mechanical torque and angular velocity of propel as well as wheel. The permanent magnet DC motor is used to simulate the vehicle speed and torque. MATLAB created surface or road gradients are used to investigate torque in different ups and downs at different angle. After analyzing battery error the proportional integral controller gain is derived for achieving desired output from the vehicle.
