MMC prototype

Project Name:                                                        Do-MMC

Identification:“Design of Modular Multilevel Converter for DC grid”

Description or Abstract:

• Aims:
  • Develop a Lab prototype of Modular Multilevel Converter (MMC)
  • The prototype must be as closest as possible to the full scale transmission grid MMC
• Main characteristics:
  • V_dc= 400V ; V_g= 116V at 50Hz ; P_rated= 5kW ; Q_rated= 1,5kVAR
  • 20 Sub-modules by arm

• Period: from October 2014 to December 2016
• Sponsors: The Nord Pas de Calais’ Council, the French State, Cinergia (Spanish Power Electronics Company) and RTE (French TSO)
• Context:HVAC to HVDC Conversion ; Transmission Power System
• Main results:
  • Develop a control architecture of a MMC with lots of switches (240 switches)
  • Use the real time simulation as an aid in the control of complex converters.
  • Produce experimental results of the MMC advance control method proposed by the team
  • Produce two copy of the prototype in order to propose a point-to-point link
