Observation on bus voltage angles through power flow computation for 2010 summer peak of South Korea

In this paper, some results of power flow computation for 2010 summer peak of South Korea are presented following introduction of the Korea power network composed of 154kV, 345kV and 765kV transmission lines. They include: - total MW on 2010 summer peak time - MW demands of major load buses - MW outputs of major generators - bus voltages of significant buses. Bus angles and the angle differences between buses are important for the study of power flow, stability, protective relaying, etc. This paper shows the magnitude of voltage angles for some meaningful buses. Magnitudes of the real and imaginary part of the complex voltage angles of the buses are compared. The spread angle of the network is also observed.
