1、电力专业英语(电动汽车)pptThe main structureConsists of electric vehicles:electric drive and control system,the driving force transmission and other mechanical systems,devices perform a given task.电动汽车的组成包括：电力驱动及控制系统、驱动力传动等机械系统、完成既定任务的工作装置等。Charging station introductionsimilar to to the Six-charge charge their

2、 cell phones ICM ladder,with a good curing effect,first activate the battery,and then proceed to maintain the fast charge,with a timer,full of alarm,the computer fast charge,password control,self-identify voltage,multiple protection,four outputs,and other functions,supporting universal output interf

3、ace can be all electric vehicle fast charging.Shopping malls,supermarkets,hospitals,car parks,the cell door,roadside canteen and other public places.The car charging network construction mode,to promote the process of charging facilities,the need to overcome the problem of charging service network d

4、istribution problem.Power sector to rely on existing parking facilities,according to local conditions to build a micro-grid,distributed,integrated rechargeable,interchangeable feature charging stations,to avoid the charge mode two short board:First,the charging time is long,two limited parking envir

5、onment.充电站介绍类似于手机充电的ICM 阶梯波六段式充电，具有较好的去硫化效果，可对电池首先激活，然后进行维护式快速充电，具有定时、充满报警、电脑快充、密码控制、自识别电压、多重保护、四路输出等功能，配套万能输出接口，可对所有的电动车快速充电。商场、超市、医院、停车场、小区门口、路边小卖部等公共场所。汽车充电网络建设模式，在充电设施推进过程中，等待突破的难题就是充电服务网络布点问题。电力部门依托现有的停车场设施，因地制宜地建设微电网、分布式、综合化的可充、可换全功能充电站，可避免充电模式存在的两个短板：一是充电时间长，二是停车环境有限。Influence1.Electric vehic

6、les have a significant energy saving and environmental advantages of great significance to promote the application of electric vehicles to reduce foreign oil dependence,the nations energy security and achieve sustainable economic and social development.电动汽车具备显著的节能减排和环保优势,推广应用电动汽车对于减少石油对外依赖,保障国家能源安全,

7、实现经济社会可持续发展具有重要意义.2.In fact,electric vehicle charging meet may focus on certain lines.When large-scale electric vehicle charging will cause tension in the local area load,resulting in the for the distribution line or transformer overload,increasing energy loss.The study showed that the electric vehi

8、cle load may be gathered in certain areas,which will cause the local distribution network overload事实上，电动汽车充电符合可能集中在某些线路当大规模电动汽车充电时，将会造成局部地区负荷紧张，导致供配电线路或变压器过载，增加电能损耗研究表明电动汽车负荷有可能聚集在某些区域，这将引起配电网的局部过负荷问题Generally,in order to meet new electricity demand,often need to dispatch high-cost and low efficienc

9、y of the marginal generator sets.Studies have shown that,under normal circumstances,the existing grid capacity to meet the considerable scale light plug-in hybrid vehiclescharging needs.Some low utilization unit or alternate unit output to meet the non-peak load periods,the majority of electric vehi

10、cle charging requirements,and transmission and distribution network is not due to the electric car charging excessive load.一般而言,为满足新增电能需求,往往是需要调度高成本和低效率的边际发电机组.已有研究表明,一般情况下,现有电网容量能满足相当规模轻型插电式混合动力汽车的充电需求通过提高某些低利用率机组或备用机组出力，能满足非峰荷时段的大多数电动汽车充电需求，而输配电网不会因电动汽车充电而产生过负荷However,the charging needs of electri

11、c vehicles has a certain randomness in time and space with the electric car ownership is increasing,a large number of electric vehicle charging will give the grid operation and management challenges.If no electric car charging for effective management,high charging rate of the same time,let the elec

12、tric car to charge even peak load hours during the day,may lead to increased peak power load,increasing the pressure of the transmission and distribution grid construction,reducing generator sets and power gridoperating efficiency.然而，电动汽车的充电需求在时间和空间上具有一定的随机性，随着电动汽车保有量的不断增加，大量的电动汽车充电将给电网的运行管理带来挑战如果不对

13、电动汽车充电进行有效的管理，在高充电同时率下任由电动汽车在白天甚至峰荷时段充电，将可能导致电网负荷高峰增加，加大输配电网建设的压力，降低发电机组和电网的运行效率From the perspective of the electric vehicle power demand factors,the probability model of the electric vehicle power requirements within one hour,according to this model,the calculation of large-scale electric vehicle c

14、harging load curve,the results show that,in the example under the conditions of electric vehiclespeak load disturbances will overlap with the original load during peak hours,the maximum load of the electric car charging needs will enable the grid to some growth occurs.从影响电动汽车功率需求因素的角度，建立电动汽车功率需求在一小时

15、内的概率模型，根据此模型，计算规模化电动汽车充电对负荷曲线的影响，结果表明，在算例条件下，电动汽车负荷高峰事端将与原负荷高峰时段重叠，电动汽车充电需求将使电网最大负荷发生一定增长On the other hand,the new electricity demand caused by electric vehicles may not necessarily need to add a generator to meet through the management of electric vehicle charging time,making the electric car charg

16、ing electricity demand can be reasonably distributed between the peak and valley periods.can effectively improve the efficiency of network operation and reduce the cost of electricity.另一方面,电动汽车引致的新增电能需求可能并不一定需要新增发电机来满足.如果通过管理电动汽车的充电时间,使得电动汽车充电的电能需求能够合理在峰谷时段之间进行分布,可以有效地提高电网运行效率和降低供电成本.此课件下载可自行编辑修改，仅供参考！此课件下载可自行编辑修改，仅供参考！感谢您的支持，我们努力做得更好！谢谢感谢您的支持，我们努力做得更好！谢谢
