A system and method for automatically tuning/configuring a power system stabilizer (PSS) in a power system digital excitation control system having an automatic voltage regulator (AVR) that includes providing a control input to the AVR as a function of generating a set of tuning PSS lead-lag phase compensation time constants as a function of received generated terminal voltages, generating an uncompensated frequency response as a function of the received set of generated terminal voltages and using particle swarm optimization (PSO) as a function of the generated uncompensated frequency response, generating a tuning PSS gain value as a function of a determined open loop frequency response of the power system, determining a PSS gain margin, determining a tuning PSS gain; and transmitting the determined set of tuning phase compensation time constants and the determined tuning PSS gain value to the control interface of the PSS.

System and method for automated tuning/configuring of a power system stabilizer (PSS) in a digital excitation control system

The present system and method provides a cross-current compensation control system that provides for improved load sharing performance during the parallel operation of multiple generators through use of a Proportional Integral PI controller or a Proportional Integral Differential PID controller eliminating steady state error in reactive current sharing, with such providing a stable and robust response with uncertain variations of equipment in the power system through improved cross-current compensation when various system parameter uncertainties exist.
