摘　　要：简要分析智能保护测试装置的特点,提出了一种通用的保护测试装置智能板卡程序在线升级解决方案,并详细介绍了设计思路。该方案采用升级程序和应用程序完全分离机制,通过网络及装置内部数据总线传输程序数据,实现程序的在线升级。该方法简单易行,通用性强,已在实际工程中得到应用。The configuration program and setting calculation of the 100% stator ground fault protection based on the NARI PCS-985B equipment are introduced by taking the reform project of generator-transformer-unit protection as an example, and the field testing data validates the correctness of setting calculation. Besides this, the problem of mismatching between the zero-sequence voltage interface of PCS-985B equipment and field device is discussed, and reasonable solution to the problem is provided.
