This paper analyzes the operation and control principle of the two transmission technologies, i.e. Line-Commutated Converter-HVDC (LCC-HVDC) and Voltage Source Converter-HVDC (VSC-HVDC) for wind farm integration. It explores the fault ride-through (FRT) capability of the two HVDC under fault conditions according to the characteristics of the two kinds of converters. To ensure satisfactory ride through grid faults, the current limit controller is initiated to reduce the active power injected into the HVDC during the fault. The approach adopted may avoid the overcurrent or overvoltage in the converter and the tripping of the wind turbines, as well as facilitate the fast recovery. Comparative simulation results verified that LCC-HVDC and VSC-HVDC could prevent the fault propagation and ensure the wind farm operation continuously in the event of severe grid fault. |
