The previous generator excitation control system is based on AVR control of generator terminal voltage. This system can't accommodate reactive power up to the facility limit even when the power system voltage decreases to the limit for stable operation. We attempted to develop advanced excitation control system (PSVR) to achieve higher constant sending end voltage of power station. We intended to apply the system to the generator connected to a 500kV system which contributes most effectively to the voltage stability of a bulk power transmission system. This PSVR produces higher control gains than the AVR, the following functions were adopted: (1) AVR gain reduction circuit, (2) phase compensation circuit, and (3) damping improvement by enlarging the limiter of the PSS. In addition, various functions were provided. These include voltage slope characteristics to balance the reactive power of adjacent generators and PSVR output and terminal voltage limiter to stabilize the generator operation. Previously to an application to a real system, a transient response test was performed by combining PSVR and generator simulator to verify the damping improvement and stability of the voltage control.
