Abstract

In the HVDC project

the equivalent interference current is often used as the standard to limit the DC harmonic level. The study of equivalent interference current simulation at different working conditions is particularly significant. In this paper

the concept of equivalent interference current is introduced and the calculation method of equivalent interference current for UHVDC transmission system is proposed.The filtering result for different DC filters is obtained by way of calculation of simulation and calculation of equivalent interference current under different DC filter mode. The study result provides theoretical calculation evidence for the selection of DC filter for HVDC transmission system.
