In this paper, is the relay on the 220KV grid. Through the design of the master and the consolidation of power system relay protection of the relevant theoretical knowledge, be familiar with the design of relay protection of power system design steps and skills, according to technical specifications, select the configuration of relay protection and demonstration of the correctness of selection and training works in practice in their own capabilities, innovation and the ability to work independently. The design is based on the Chongqing Water Conservancy and Electric Power Vocational Technology College students of the graduation requirements of the design. The main elements of the design of 220KV power system relay protection configuration and tuning, design elements include: Introduction Chapter; computing systems in the second chapter of the main parameters of the various components; power lines on the road in Chapter III TA, TV changed over the choice and the choice of neutral grounding; Chapter IV grid short-circuit current calculation; section of chapter V of electricity network selection phase distance relay with the setting; Chapter VI of zero-sequence power network relay protection options and setting; Chapter VII the choice of automatic reclosing. Relay to adapt to a variety of changes in the power system's ability to run is limited, therefore, for the relay setting program will be different with different protective effects, how to determine the best setting of a program, it will be engaged in relay protection engineering research. In short, the relay setting both their own skills as well as relay configuration and selection of problems, but also the power system structure and functioning of the problem. In particular, for this article 220KV high-voltage line current differential protection phase put into operation at the scene prior to testing, and technical personnel has been a problem, because lines at both ends of the distance restrictions, on-site laboratory tests can not be as easy as. Keywords: relay coordination program with the power system structure and operation of

在中文当中的TA 有“他”和“她”两个字，但在这张图片中只须要一个字。 所以就用一个“TA”字来代替“他”和“她”了，这能让人读起来就不再去区分两个字中的那一个了。

意思是，只要是人，不管是男的，女的，老的，少的，什么的，什么的都在内了，如果你认为它也可以用手机带钥匙，那也算上得了，不过后边有最好人也掉进去，那就只能是人了。

继电保护这个地区电力系统设计涉及的最小化和限制服务灭弧室损坏设备失效发生。继电保护的作用是造成及时去除一个有缺陷的元素从动力系统。有缺陷的元素可以有一个短路或可运行在一个异常的方式。继电保护系统设计检测这样的失败或非正常条件下快速打开一个最低的断路器隔离有缺陷的元素。快速分离的效果有三个:(1)它减小或防止损害到有缺陷的元素,从而减少修理的时间和费用,并允许更快恢复元素服务;(2)它使严肃性和持续的有缺陷的因素影响电力系统的正常运行;(3)的力量,它能最大限度的实现可以转移在动力系统。第二个和第三个点特别的意义,因为它们表明继电保护的重要作用是在保证最大限度延长使用可靠性和系统设计中。能传送的力量,在系统无损失的同步故障清除的作用时间。很明显,快速故障清除一个更高的功率传输时间允许比长时间清理。高速清除故障经常提供了一种手段来实现更高的权力的转移,从而延缓投资在额外的传输设备。

220 KV electrified wire nettings succeed electricity protection Being studying protects the main body of a book about that 220 KV electrified wire nettings succeed an electricity. By the knowledge designing that electric system succeeds the relevance special field theory that the electricity protects originally time grasping and firming,know well that electric system succeeds the design step that the electricity protects and designs a technical ability, according to the technical code , choose the ability applying the ability , ability to innovate and autonomous working in deploying the project choosing the type correctness and cultivating self in practice that the electricity protects then and expound and prove. Design the graduation practice being that the two-year college graduate graduates demanding but is on the march according to Chongqing water conservancy electric power occupation Tec originally time. The content being that 220 KV electrified wire nettings succeed allocation and adjusting that the electricity protects , designing that includes the main content designing that this time: The first chapter introductions; Every component main part is parametric among second chapter calculation system; TA , choice and neuter that TV unexpected turn of events is compared to count grounded choice third chapter power lines on the way; Fourth chapter power network short-circuit current calculation; Fifth chapter power network alternates from when then, electricity protection way chooses and adjusting secretly schemes against; Sixth chapter power networks zero order succeeds an electricity protecting way choice and adjusting secretly scheming against; Seventh chapters highly value the choice switching in voluntarily. That the electricity protects the ability that the operation adapting to electric system changes all is limited then since various , the composition protecting the adjusting scheme to succeeding an electricity is unlike protection effect that can have no equal to as a result, how to ascertains a optimum adjusting scheme , will be to be engaged in the go into problem giving the engineers and technicians who protects a job an electric shock then. In short ,succeed electricity protection now that the adjusting having oneself artifice problem, there be the problem succeeding an electricity protecting allocation and choosing a type, to still have the electric system structure and to run a problem. 220 KV high-tension lines mark of each other voltaic differential protection throws the scene experiment transporting front especially , with regard to in the main body of a book , is always to perplex a problem of technician , restrict since circuit both ends is at a distance of, the scene experiment can not go to the lavatory like laboratory.【标准翻译后的结果】
