摘　　要：根据国标GB/T 1029—93和美国标准IEEE std 115—1995推荐的保梯电抗法,目前制造厂确定同步电机额定负载下的励磁电流所采用的作图计算法,既费工时又存在人为随机误差。采用Microsoft Excel2000软件包(以下简称Excel软件)编制了数值计算程序。该程序方便快捷、计算结果精度高,同时还可用于电厂负载温升试验时额定负载励磁电流的推算和无刷励磁同步发电机负载励磁电流及转子平均温度等的间接测定。A calculation procedure of excitation current on load of synchronous generators is compiled by using Microsoft Excel 2000 package, which is based on Potier Reactance method recommended by the Chinese standard GB/T 1029 and the American Standard IEEE std. 115-1995. The calculated result shows that the procedure is more convenient and accurate than the traditional drawing numeration. This procedure can also be applied to the calculation of excitation current when temperature rise test is performed at rated load, the on-load excitation current and average temperature of the rotor for brushless excitation synchronous generator.
