毕业设计(论文)论 文 题 目:变电站电气一次系统设计专 业: 电力系统与其自动化专业 容 提 要随着电力体制改革的进一步深化，电网建设得到了迅速进展，为了适应市场机制，提高经济效益，促进电网安全稳定运行，越来越多的变电站实现了无人值班。实践表明，无人值班方式增强了设备可靠性，简化了生产管理环节，降低了电力建设造价，推动了供电网络运行科学化管理。因此，变电站实行无人值班已成为电网进展的必定趋势。本设计为 110kV 变电站电气一次部分初步设计，采纳无人值班管理模式和综合自动化控制方式。本设计一次部分严格根据无人值班变电站设计规程的规定进行设计。该变电站装设两台主变压器，站电气主接线分 110kV 和 10kV 两个电压等级，110kV 和 10kV 接线同样采纳单母线分段接线方式。本设计正文分设计说明书和设计计算书两个部分：设计说明书包括概述、电气主接线方案的比较和确定、变压器选择、短路电流计算说明、电气设备与导线选择。设计计算书包括短路电流计算、电气设备选择与校验。关键词：110kV 变电站；电气主接线；电气设备SummaryWith the further in-depth of electric power system reform, electric network construction has been developed rapidly. In order to adapt the market mechanism, increase economic benefit, promote the electric network being safe to be run steadily, more and more unattended substations have been realized. Practice indicates, the unattended way has strengthened the dependability of the equipment, simplified the link of production management. It reduces electric power build fabrication cost and promote power network manage run scientific. So, the substation implements unattended mode has already become the inexorable development trend of electric network.This design is for the electric departmentdevice of the110kVhigh-voltage substation to adopt unattended management mode and integrated automation system. The designabide strictly the rules of the unattended substation design regulations. This transformer substation installs two main transformers, in the stat...
