The place of performance of a power supply contract shall be the place prescribed by the parties , and if not prescribed or clearly prescribed , the place of performance shall be the boundary where ownership of the power supply facilities is divided 第一百七十八条供用电合同的履行地点，按照当事人约定；当事人没有约定或者约定不明确的，供电设施的产权分界处为履行地点。
Zhang guobao , vice - minister of the national development and reform commission , said that china will require a power supply of 11 , 000 billion kilowatt hours by 2020 , needing generating units with a total capacity of 2 , 400 , 000 megawatts 虽然对于国家质检总局“名牌战略推进委员会”是否应该进行这样的评选，社会上有一些不同看法，但是从汽车行业来说，客车企业完全有理由成为汽车行业的“名牌先锋队” 。
Compared with a power supply made in other ways with the same capacity , the same number of outputs and the same isolation voltage , the power supply discussed in this paper has the advantages of small in size , light in weight , high efficiency and reliability , low cost and so on 相对于用其他方式研制的具有相同输出路数、相同功率、相同隔离电压的电源，新型电源具有体积小、重量轻、效率高、可靠性强、价格低等显著优点。
Then this article analyzes the way to obtain the power of measuring device . also it recommends two kinds of feasible schemes of mutual inductance power and solar power , and proposes a power supply scheme that is called " the optic fiber supplying power " in the paper . the feasibility of this scheme is also analyzed here 文章接着对测量装置的电源获取途径进行分析，介绍了互感供电和太阳能供电两种可行的方案，并提出了本文称之为“光纤传光供电”的供电方案，具体分析该方案的可行性，并设计了该方案的主要组成部分解决了中高压系统参数测量中的两个共同问题以后，文章设计了中高压系统温度在线监测装置。
A power supply contract includes terms such as the method , quality , and time of power supply , and the capacity , location and nature of power use , and the metering method , electricity rate , the method of settlement of electricity charge , and the responsibility for maintenance of the power supply and power use facilities , etc 第一百七十七条供用电合同的内容包括供电的方式、质量、时间，用电容量、地址、性质，计量方式，电价、电费的结算方式，供用电设施的维护责任等条款。
At present , the key technology of edm power supply is how to design a power supply with simple circuit , finish maching , high heat availability , high efficiency and wasting less energy , so a current source lcc resonant converter is selected for the edm power supply in this paper , the prototype of current source and load adaptability are used to get the performance of simple circuit , finish maching , high efficiency and wasting less energy . at first , the status quo of edm power supply is introduced in this paper , the design of an edm power supply is comfirmed after the characteristics of current edm power sypply has been summarized . secondly , the principles of the lcc resonant converter are analyzed in detail 本文首先介绍了edm电源的研究现状,在总结当前edm电源特点的基础上,确定了采用电流型lcc串并联谐振变换器作为主电路拓扑的设计方案,其次,对拓扑进行了详细的原理分析,由于电流型lcc串并联谐振变换器众多参数是相互影响的,在对edm电源系统进行分析与仿真基础上,对参数设计进行了优化设计,再次,对拓扑及edm电源进行了建模与仿真分析,确保了该edm电源设计的可行性,最后研制了输出峰值电流为20a的电流型edm电源样机,并通过对原理样机的实验,验证了参数优化设计的正确性及电流型lcc串并联谐振变换器的edm电源的优越性。
