Abstract :
The new system studied in this paper is made of late-model single chip microcomputer and personal computer. It not only can monitor networks´ frequency in real-time but also can calculate frequency variable then distinguish and record frequency fault course automatically. The whole recording time can come to 30 minutes. It is also equipped with data analytic software under WINDOWS circumstance. The new system can be used in power plants, substations and all levels dispatching station. It will play an important role in monitoring and recording networks´ frequency.The recorded messages will be used in analyzing system frequency characteristic and under- frequency load shedding devices´ performance. It has been used in power system and the effect is very good.
