利用同步电机的某些瞬变过程检测同步电机参数是常用的方法。同步电机瞬变过程持续的时间很短,只有零点几秒到几秒,常规的方法是用示波器将电机瞬变过程的数据记录,然后从示波图上读取数据来计算分析得出有关参数,其精度难以保证。本文以抛截法(1)测同步电机参数为例,介绍了单板机在电机瞬变过程数据采集中的应用,系统的组成及软件设计,使求取参数的方法简单而且精度提高。 It is common practice to detect synchronous motor parameters using some of the transient processes of a synchronous machine. Synchronous motor transient process continued for a very short time, only a few tenths to a few seconds, the conventional method is to use the oscilloscope motor transient data records, and then read the data from the oscilloscope to calculate the analysis of the parameters , Its accuracy is difficult to guarantee. Taking throwing method (1) as an example to measure synchronous motor parameters, this paper introduces the application of single board computer in the process of motor transient data acquisition, system composition and software design, so that the method of obtaining parameters is simple and the accuracy is improved.
