The device to measuring of the load angle for salient-pole synchronous machine in education laboratory

摘要

This paper presents information about a new device for measuring the synchronous machine load angle in laboratory conditions using the optical encoder. The prototype device is used in education for practical measuring exercises in the study course of electrical machines. Described in the article is block diagram of the measuring device. The operation principle of the device and the measurement principle of load angle of the synchronous machine presents a subject of the article, too. Moreover, the device evaluates operating mode (motor or generator) of the synchronous machine.
