To adapt to high-voltage large-capacity voltage source converter based high voltage direct current transmission (VSC-HVDC) system, this paper put forward a new valve base control structure, namely multi-agent system (MAS), featuring distributed computing, intelligence, real-time and sharing. With the MAS-based valve base control technology, problems such as massive data acquisition, complex algorithm implementation and comprehensive protection evaluation could be easily overcome. Comparative simulation and performance tests of the MAS structure and the redundant hot standby structure were carried out on the digital-analogue hybrid simulation platform, which proved to be scientific and rational, and thus provides a theoretical support and engineering foundation for the valve base control technology aiming at high-voltage large-capacity VSC-HVDC systems up to hundreds of MW.
