110kV数字化变电站二次部分设计 电气工程专业

摘要电气二次部分设计是对一次部分的测量回路、保护回路和控制回路的设计，主要包括的二次功能元件如下：测量仪表、通讯传输系统、继保设备、自动和远传通信设备等。电气二次部分设计是变电站设计中不可缺少的重要环节，二次设计方案的合理性对保证变电站可靠、稳定、安全的运行起着非常重要的作用。变电站监控系统具有遥测、遥信、遥调、遥控（简称“四遥”）等其他远动功能。对于全站来说，还有一套同步对时装置实现对其时钟校正。变电站监控系统还应具备与远方工作站之间的数据交换的功能。总的来说，对完成全站稳定、恰当、充分的监视，计算机监控系统的影响力也是不可替代的。本文根据变电站二次部分设计规程规范，对某 110kV 数字化变电站计算机监控系统部分展开相关设计工作，主要有：对本变电站的二次部分的功能进行分析并总结；对变电站二次部分开展总体方案设计；读懂厂家提供的二次图纸，熟悉厂家提供的保护设备型号和功能；遵循数字化变电站计算机监控系统的配置原则，设计本变电站的计算机监控系统。结合变电站实际一次图纸，给出了本次设计所需要的计算机监控系统组网方案，最终圆满地完成了本次设计。关键词：变电站，二次设计，计算机监控系统IABSTRACTElectrical secondary part design is part of a measuring circuit, protect circuit and control circuit design, mainly includes the quadratic function of the components are as follows: measuring instrument, communication transmission system, the equipment, automatic and remote communication equipment, etc. Electrical secondary part design is an important and indispensable link in the design of substation, the rationality of the design of secondary to ensure the safety of substations, stable and reliable running plays a very important role.Substation monitoring system with remote sensing, remote communication, remote adjustment and remote control (hereinafter referred to as the "four control") and other remote function.
