35KV变电站设计论文研究分析.docVIP

巍山35KV变电站设计 摘 要 本文是根据中华人民共和国电力公司发布的《变电所设计规程》编写的。 变电站是电力系统的重要组成部分，它直接影响整个电力系统的安全与经济运行，是联系发电厂和用户的中间环节，起着变换和分配电能的作用。电气主接线是变电所的主要环节，变电所的电气主接线，是由高压电器设备通过连接组成的接受和分配电能的电路。反映各设备的作用、连接方式和各回路间相互关系，从而构成变电所电气部分的主体。它直接影响着配电装置的布置、继电保护的配置、自动装置和控制方式的选择，对电力系统运行的可靠性、灵活性和经济性起决定性作用，在确定主接线时，电气接线要满足必要的供电可靠性和保证供电的电能质量。另外主接线应能适应各种运行方式，具有发展和扩建的可能性。 本次设计为35KV变电站初步设计，共分为任务书、说明书、计算书三部分，所设计的内容力求概念清楚，层次分明。 关键词：电 力；电 气；自 动 装 置；电 气 主 接 线 ABSTRACT The weishan 35 kv transformer substation design This text releases according to the Peoples Republic of China power company of 《 the changes the electricity the rules distance design 》. The transformer substation is the importance of the electric power system to constitute the part, it affects the whole safety of electric power system and economies to circulate directly, is a middle link that contacts the power plant and customers, rise the transformation and assign the function of the electric power. The electricity lord connects the line is the vital link that the power plant changes to give or get an electric shock, The electric main connection in transformer substation is the main part of the transformer substation formed by a circuit to receive and distribute power formed by connection via high voltage wiring and reflect all kinds of facilities’ usage, connection manners and relationship between each loops. it will directly affect the collocation of power distribution, configuration of relay protection, choice of automatic equipments and control mode, and have a decision for reliability, agility and economy of power system When ascertain the main connections, power connection shall meet the power reliability and guarantee the power-supply quality. In addition, main connection shall suite to all kinds of operations, and possess the possibility of development and enlargement. This time designs to design for the 35 KV transformer substation first step, ising divided into three parts of mission book, manual, the calculation book totally, the content
