【摘要】：在化石燃料逐步耗盡,環(huán)境污染日益嚴(yán)重的今天,電動汽車作為新一代環(huán)保的交通工具,獲得了長足的發(fā)展,電動汽車的保有量日益增長,國內(nèi)出臺了各種政策來支持電動汽車的發(fā)展,電動汽車充電站是電動汽車運行不可缺少的重要配套設(shè)施,電動汽車充電站的數(shù)量直接影響了電動汽車的發(fā)展速度。但是,大量的電動汽車充電站的設(shè)置也為配電網(wǎng)的運行帶來了不利的影響,其能耗和諧波都會配電網(wǎng)的正常運行造成一定的影響。本文在結(jié)合了國內(nèi)外對電動汽車充電站電能質(zhì)量和能耗分析結(jié)果的基礎(chǔ)上,對電動汽車充電站的電能質(zhì)量問題和能耗問題進(jìn)行了分析和研究。首先搭建了電動汽車充電站模型,分析了不同類型的充電機(jī)的特點,然后利用所搭建的模型,對不同類型充電機(jī)的電能質(zhì)量和能耗進(jìn)行了分析,隨后對余杭地區(qū)的電動汽車充電站能耗情況和電能質(zhì)量問題進(jìn)行了分析。分析結(jié)果表明,余杭地區(qū)電動汽車充電站的能耗和電能質(zhì)量能夠滿足要求,但是在未來的發(fā)展中需要考慮其不利影響。
[Abstract]:With the gradual depletion of fossil fuels and the increasingly serious environmental pollution, electric vehicles, as a new generation of environmentally friendly means of transportation, have gained considerable development, and the number of electric vehicles has been increasing day by day. Various policies have been introduced in China to support the development of electric vehicles. The charging stations of electric vehicles are indispensable supporting facilities for electric vehicles. The number of charging stations of electric vehicles has a direct impact on the speed of development of electric vehicles. However, the installation of a large number of charging stations for electric vehicles also has a negative impact on the operation of the distribution network, and its energy consumption and harmonic will have a certain impact on the normal operation of the distribution network. On the basis of analyzing the power quality and energy consumption of electric vehicle charging station at home and abroad, the power quality problem and energy consumption problem of electric vehicle charging station are analyzed and studied in this paper. Firstly, the charging station model of electric vehicle is built, and the characteristics of different types of charger are analyzed. Then, the power quality and energy consumption of different types of charger are analyzed by using the model. Then the energy consumption and power quality of electric vehicle charging station in Yuhang area are analyzed. The results show that the energy consumption and power quality of the electric vehicle charging station in Yuhang area can meet the requirements, but the adverse effects should be considered in the future development.
