Abstract :
This paper presents an advanced time domain model of a three-phase cycloconverter for Low Frequency alternating Current (LFAC) transmission systems. The model is based on the quadratic integration method. The proposed time domain model has been demonstrated to be accurate, robust, and reliable as compared to other integration methods such as the trapezoidal integration. The goal of this paper is to present a realistic model of a three phase cycloconverter and to integrate this model in an advanced time domain simulation method for LFAC systems. Examples of wind farms with LFAC transmission systems are presented. Furthermore, the proposed method is expected to be used for transient stability studies, harmonic studies, and fault studies of wind farms with LFAC transmission systems.
