摘　　要：本文就八位机用于同步发电机失磁保护的可行性问题进行了探讨和论证,推导了适于八位机减少运算量和计算时间的算法,给出了避免直接乘法运算的快速查表法并提出了一种计算机失磁保护方案.1The feasibility of using an 8-bit microcomputer for generator loss-of-excitation protection is studied. A specific scheme is proposed. The combination of 'square algorithm' with 'quick table look-up method' has improved the real-time calculating speed of the 8-bit microcomputer and made it possible to realize the scheme proposed.
