摘要

提出了一种利用过流继电器保护3.5 kVA发电机绕组的低阻抗保护方案，分析了基于该方案的限制接地故障差动保护。7SJ85过流保护继电器的配置和测试主要集中在其内置的ANSI 87N、REF保护功能上。组成保护系统的元件的配置、参数化和操作使用OMICRON的CMC 356和7SJ85继电器，以及各自的应用软件Test Universe和Digsi 5。测试所使用的数值是基于采用IEC 60909标准和Complete方法(相当于Thevenin)进行的短路分析，分别在MatLab和DigSilent软件中进行计算和仿真。

Differential Protection Analisys For Detection Of Ground Faults On the Generator Stator

The analysis of the restricted earth fault differential protection based on the implementation of a low impedance scheme that allows the protection of 3.5 kVA generator windings using the overcurrent relay in differential structure is presented. The configuration and testing of the 7SJ85 overcurrent protection relay is mainly focused on the built-in ANSI 87N, REF protection function. The configuration, parameterization and operation of the elements that make up the protection system are performed using OMICRON's CMC 356 and the 7SJ85 relay with their respective application software Test Universe and Digsi 5. The values used for the tests are based on the short-circuit analysis applying the IEC 60909 standard and the Complete method (equivalent to Thevenin), which were calculated and simulated in MatLab and DigSilent software respectively.
