Abstract

Abstract:

As to resolve the problem of poor performance of STATCOM due to the inefficient performance of PI controller in drastic fluctuating electric environment,a precise discrete mathematical model of the STATCOM is built and a current prediction method originated from Lagranges interpolation is proposed,which attain a high quality prediction of current,consequently resolving control error caused by time-delay due to digital calculation and improving the instantaneity of the current detection,according to the simulation in Matlab.

Key words: deadbeat;control Lagranges interpolation;current-prediction;STATCOM
