Abstract:

Aiming at the transmission of receiving distribution system connected by multi-infeed voltage source coverter high voltage direct current (VSC-HVDC), the controller for converters of VSC is developed from the prospective of active power and alternating voltage regulation, while the eigenvalue analysis is introduced to investigate the influence of the control strategy on the system stability. In order to verify the feasibility of the control scheme, simulations have been done on the platform of PSCAD/EMTDC. It is shown that the topology of the multi-infeed VSC-HVDC can provides a cost-effective way to supply power to the receiving grid, which is also of satisfactory control effects.
