摘要:This paper presents a procedure for modeling and
tuning the parameters of Thyristor Controlled Series Compensation
(TCSC) controller in a multi-machine power system to improve
transient stability. First a simple transfer function model of TCSC
controller for stability improvement is developed and the parameters
of the proposed controller are optimally tuned. Genetic algorithm
(GA) is employed for the optimization of the parameter-constrained
nonlinear optimization problem implemented in a simulation
environment. By minimizing an objective function in which the
oscillatory rotor angle deviations of the generators are involved,
transient stability performance of the system is improved. The
proposed TCSC controller is tested on a multi-machine system and
the simulation results are presented. The nonlinear simulation results
validate the effectiveness of proposed approach for transient stability
improvement in a multimachine power system installed with a
TCSC. The simulation results also show that the proposed TCSC
controller is also effective in damping low frequency oscillations.
