摘要
RCS— 91 5 B型母线保护装置具有母联带路的功能 ,但要求有专用旁路母线 ,淮北电厂无专用旁路母线 ,文中分析表明在旁带操作过程中会出现差动电流 ,通过对主系统运行方式及差流计算方法分析 ,给出了解决此问题的方法。
RCS 915B microprocessor based bus protection unit has the function of bus coupler substituting branch, which needs special bypass bus. There is no special bypass bus in Huaibei Power Plant, which results in differential current in the process of bypass substituting branch operation. A solution to this problem is worked out in this paper through the analyses of the primary system operation and the calculation of differential current. Besides, this paper introduces the primary technical advantages in the application of this unit.
