| Abstract: | Real time measuring of power phase angle with high precision is a key technique for the monitoring and controlling system of dynamic safety and stabilization of electric power systems.Traditional measuring method of power phase angle of a generator can't meet the real time requirements,therefore a new method utilizing the rotating speed of the generator based on GPS has been proposed.The principle and realization mode of the distributed measuring unit is described.Experimental result proved that synchronization between each vector can be realized by this method and the synchronization of real measured phase angle is assured.The method has theoretical and practical value. |
