Abstract: | The authors present the analytical development of a controller scheme for a static VAr system and present detailed simulation results to highlight its effectiveness in comparison with a discrete PI (proportional-integral) stabilizer under a variety of operating conditions for power transmission systems. The adaptive stabilizer is suitable for microprocessor digital implementation as the numerical steps involved are minimal. The adaptive stabilizer uses a stochastic variant simplified parameter estimator routine, thus providing a faster sampling rate and identification of a larger number of parameters in real time. The implementation of this stabilizer is simple as it involves additions, multiplications without matrix inversion, etc |
