2、.11.21 2014 年 11 月 30 日Abstract With the increasing shortage of energy, electric automobile as an energy-saving and environment-friendly vehicle has been given more and more importance by governments all over

3、 the world. However, the emergence of a large number of electric cars not only increases peak load, but also brings harmonic wave pollution, which will inevitably cause enormous impact to the power system. Because automo

4、bile charging station is an energy supply infrastructure, it therefore becomes an issue of crucial importance to further study the charging mode of electric automobile as well as the influence of charging stations on gri

5、d power quality. In this paper, based on domestic and foreign researches on this issue, and through analysis of harmonic waves of different kinds of battery chargers, electrical topology models of three-phase controlled

6、 rectifier, high frequency PWM rectifier, and active power factor correction were established, and a simulated analysis of the evaluation of harmonic waves was made. We built a charging station load curve by using the mo

7、nte carlo algorithm, established a fast charging station load model, made an simulated analysis of the effect of fast charging stations to the power grid, and made a transient stability analysis of charging stations usin

8、g a six-section power model. We carried out a research on the information management system of electric automobile and battery based on automobile terminal. The research results of this paper have been applied to project

10、y in the planning, operation monitoring and coordinating and scheduling of charging station networks. At the same time, because statistical data on actual grid operation is incomplete and the analysis of the impact of ch

11、arging stations on grid quality lacks actual calculation support, the transient stability analysis is conducted only on the basis of the typical models, in the future, complete analysis and measurement of power change ca
