Abstract

The current study proposes the utilization of solar panels to power high frequency speed buses like the Bus Rapid Transit in Am-man city.  Based on Photo Voltaic technology, mounting PV solar panels system on the top of the track of the high frequency bus, ar-ranged at azimuth angle ranging between 0°- 90° with the best tilt angle measured 12°, along an actual unshaded track of 18 km (of the 25 km total pathway track), resulted in the generation of more than18 MWp (On Grid system). Such power is used not only to charge the bus and to operating facilities inside the city instead of the conven-tional ways as illustrated in the coming later.

Abstract

The present study is mainly concerned with solving the problems associated with energy losses resulting from starting transient conditions. In the present study, the possibilities of decreasing starting transient condition energy losses are investigated. Additionally, a comparison of the energy losses using different starting methods is also conducted. In this work, a complete description for deriving the equations used to calculate energy losses, mathematical analysis of the energy losses, the models of the different methods in this work were simulated using MATLAB/Simulink; and the results of energy losses and the dynamic characteristics are provided. Simulation results showed that the minimum starting energy losses were accomplished by soft starting method, in which the starting current could be reduced to the minimum value.
