Abstract: This paper is used to evaluate the negative sequence currents (NSC) of two generators in a generation plant, which are connected to the power pool through four asymmetrical 345-kV transmission lines. The two generators are located at the southern end of the Taiwan Power (Taipower) grid. These generators are very important to the system and provide base-period generation power. The simulation results by using PSS/E and EMTP are checked with the values from the wide area measurement system (WAMS). It can be observed that the factors such as parallel operations, lengths, current directions, and co-towered conditions of transmission lines will affect the values of NSC. The arrangement of conductors on the same tower in RST-R¡¦S¡¦T¡¦ or RST-T¡¦S¡¦R¡¦ configuration will have significant effects on the NSC values. This study estimates whether the generators need to reduce loading owing to the NSC to protect the generators. The study results give important information abou!
