DC offset removal of thyristor switched series capacitor and in a novel and simple method
Author(s): M Mahdi Mansouri, Majid Nayeripour
Abstract: As a DC offset is produced when each step of Thyristor Switched Series Capacitor (TSSC) come in and out operation, this DC offset is analyzed and effective parameters are discussed. Then a simple method for its elimination is proposed. The first result of proposed method is that DC offset is removed in half cycle. Another advantage of proposed method is that delay time of TSSC steps for outage reduces from one cycle to half cycle. It means that operation response of TSSC is improved. The proposed method can be used in other series compensators with multi steps.
