摘 要
变电站作为电力系统中承担升降压与潮流调整功能的重要组成部分，一旦发生故障得不到及时有效的解决，将会引起整个电力网的异常甚至是崩溃。而变压器作为变电站中的核心设备，其安全等级决定了整个变电站的运行效益。所以，一个安全、可靠、经济的变压器保护设计，将会对电力系统的运行起到至关重要的作用。
本文是对给定资料的220kV变电站主变压器保护进行配置与整定计算的设计说明书。该设计的主要过程为：通过对该变电站原始资料进行分析，进行电气一次主接线设计后，得到电网简化图，从而有针对性地对其主变压器保护进行配置及整定计算。其中计算部分主要包括短
路电流计算、设备选型参数计算、保护配置的整定计算；所需绘制的工程图纸主要有电气一次主接线图和变压器保护配置图。

ABSTRACT
Substation is very important in the power system because of its function of changing the voltage and adjusting the trend of power. When of faults are not be solved timely and effectively, they will cause the irregular operation or even collapse in the power system. T
he transformers are regarded as the core equipments in the substation, its safety level determines the running benefit of the whole substation. That’tsmms to say, a safe, reliable and economic design of transformer protection, will play a crucial role in the operation of the power system.
This article is the instruction and procedure of the configuration and setting calculation of a main transformer protection in a 220kV substation. Analyzing the raw data of the substation, determining the main electrical wiring forms, and then we can get the grid simplified diagram, which is used for doing configuration and calculation of the main transformer protection. The part mainly includes the short circuit current calculation, equipment selection, and the setting calculation of the protection configuration. The main electrical wiring diagram and the protection’s configuration diagram will be needed.
