The importance of generator power angle is described briefly. Measurement method and calculation method to determine generator power angle are introduced. A generator power angle calculation model based on synchronous phasor measurement is presented. It makes use of generator's sampling data of voltage and current. The method is simple to master, easy to realize, and good to model adaptability,which can be used in real-time power angle calculation. Simulation results reveal that the method has fine accuracy while metting engineering demand. When the method is used in whole net phasor measurement systems, dynamic variations of power angle can be monitored accurately. It lays a foundation for the safety and stability monitoring of system.
