220KV变电站综合自动化 -110KV第八回出线保护配置及整定计算 摘要 本设计主要介绍了220KV变电站综合自动化的110KV出线保护设计的过程、原则、方法等，利用现在广泛采用的微机保护原理和整定的新方法进行配置. 关于主接线部分的内容是基础部分，主要介绍了主接线的形式，综合比较各种接线方式的特点、各自的优缺点及变压器的选择原则等，根据任务书要求最终选择满足设计任务的主接线方案。短路电流是非常重要的部分，它主要介绍了不同运行方式下的对称短路与不对称短路计算的目的、原则、方法和具体的数据信息等，为设计中需要的高压电气设备的选择、整定、校验等方面做准备，电气设备的选择及校验主要是利用对称短路的计算结果进行高压电气设备（断路器、隔离开关）的校验。设计的专题部分，也是利用短路计算的结果，详细阐述了继电保护中配置的选择、整定和校验的原则、方法等，具体有反映相间短路的电流电压保护的整定计算与校验；反映接地故障的零序电流保护的整定与校验。 关键词：综合自动化，微机保护，继电保护，整定与校验 Abstract The main design on the 220 KV substation automation 110 KV wit to protect the design process, in principle, methods to take advantage of the currently widely used computer protection principle and the entire set of new methods for allocation On the main wiring part of the contents of infrastructure, mainly on the main wiring in the form of Comprehensive comparison of different forms of connection characteristics, advantages and disadvantages of each option transformer principles, Under the mandate calls for a final choice on the design of the main tasks Connection program. Short-circuit current is a very important part, It introduces a different mode of operation under the symmetric and asymmetric short-circuit short-circuit the purposes of the calculation, methods and specific data information for the design of the high voltage electrical equipment selection, tuning and testing and so on preparations Electrical equipment selection and verification is using symmetric short-circuit the calculation results of high voltage electrical equipment (devices, disconnector) calibration. Part of the design feature, as well as the use of short-circuit calculation, a detailed explanation of relay protection configuration choices, Setting and checking the principles and methods, the specific phase is reflected in the current-voltage short circuit protection of the setting and calibration; Ground Fault reflect the zero-sequence current protection of the setting and calibration. The final three chapters as is the design of
