摘要:本研究以国内某大型浆厂自备热电站厂用电中压系统为对象，利用ETAP电力系统分析计算应用软件为辅助工具，基于该项目所配套的南瑞综合保护测控装置，探讨了10 kV厂用电系统各种类型的用电设备及发电机的继电保护整定计算，从而在满足继电保护4项基本要求的前提下，寻求继电保护整定的最优方案。

Abstract:Using ETAP power system analysis and calculation application software as an auxiliary tool， based on the supporting equipment NANRI comprehensive protection measurement and control device of this project， the relay protection setting calculation of various types of electrical equipments and generators in the 10 kV auxiliary power system was discussed with the auxiliary power medium voltage system for self-contained thermal power station of a large domestic pulp mill as an object in this study. The optimal scheme of relay protection setting was sought while met the four basic requirements of relay protection setting.
