Power control of low frequency AC transmission system using cycloconverters with virtual synchronous generator control

摘要

This paper presents a new control scheme for a multi-terminal low frequency ac transmission system (LFAC) operating with a cycloconverter. The multi-terminal sytem uses two-phase LFAC system with a 12-pulse thyristor converter. A control scheme for power control by Virtual Synchronous Generator (VSG) among each terminal is explained in detail to understand the advantages of this method. Circuit configurations and parameters of the application are addressed. Simulation results are provided to illustrate the proposed control scheme on the LFAC system's performance.
