摘 要
在经济迅猛增长和人们生活标准不断提升的背景下，汽车逐渐成为了我们日常生活里不可或缺的移动工具。但是，传统汽油车的环境和能源代价日渐凸显。电动汽车以其低排放、小污染、低噪声等优点，被视为解决上述问题的重要途径。作为基础服务设施，水厂增设电动汽车充电站对电动汽车产业的推广和商业化进程具有关键推动作用。
本篇概述了全球及中国电动汽车充电设施的现有进展，以太原市为例，揭示了电动汽车的广泛应用潜力。随后，本文深入研究了电动汽车充电站的基础理论，并对某水厂5×120kW电动汽车充电站的配电系统进行了详细设计。设计过程中，依据相关规范和要求，在本研究中，我们精心挑选了核心设备，并运用AutoCAD软件精心绘制了配电系统的电气主接线图。为了确保充电站的顺畅运行，本文还深入分析了谐波控制与无功功率补偿设备、继电保护系统以及电力供应监控系统等辅助设施的配置。本研究旨在为某水厂电动汽车充电站的建设提供理论支持和实践指导，促进电动汽车的广泛应用和可持续发展。

Abstract
Under the background of rapid economic growth and rising people's living standards, cars have gradually become an indispensable mobile tool in our daily life. However, the environmental pollution and energy crisis brought about by the traditional internal combustion engine vehicles are increasingly serious. With their advantages of low emission, small pollution and low noise, electric vehicles are regarded as an important way to solve the above problems. As an infrastructure unit, the construction of an electric vehicle charging station is of great significance for promoting the commercialization and industrialization of electric vehicles.
This paper first summarizes the development status of electric vehicle charging stations at home and abroad, and takes Taiyuan city as an example to show the broad application prospect of electric vehicles. Subsequently, this paper studies the basic theory of the electric vehicle charging station deeply, and designs the power distribution system of the 5120kW electric vehicle charging station of a water plant in detail. During the design process, according to the relevant specifications and requirements, in this study, we carefully selected the core equipment, and used AutoCAD software to carefully draw the main connection diagram of the power distribution system. In order to ensure the smooth operation of charging stations, this paper also deeply analyzes the configuration of auxiliary facilities such as harmonic control and reactive power compensation equipment, relay protection system and power supply monitoring system. This study aims to provide theoretical support and practical guidance for the construction of an electric vehicle charging station in a water plant, and to promote the wide application and sustainable development of electric vehicles.
