摘要
分析了2×300 MW燃煤式火力发电厂发电机、变压器的继电保护.对发电机进行了整定,并选择了发电机的定子绕组匝间保护.同时,对变压器进行了简单整定,通过对变电所变压器的瓦斯保护、差动保护、过电流保护,完成了本次继电保护的设计.通过此次设计,熟悉了电力系统继电保护的设计方法,提高了实际动手能力.
Abstract
Analyzed the relay protection of generators and transformers in a 2×300 MW coal-fired thermal power plant.The generator was tuned and the stator winding inter turn protection of the generator was selected.At the same time,a simple setting was carried out on the transformer,and the design of the relay protection was completed through the gas protection,differential protection,and overcurrent protection of the transformer in the substation.Through this design,have become familiar with the design methods of power system relay protection and improved my practical ability.
