This paper presents control strategies for a DC transmission system connecting onshore/offshore wind farms to the power network. These control strategies aim to allow the VSC-HVDC transmission system to meet the Great Britain (GB) Grid Code regarding frequency support, voltage/or reactive power support and Fault Ride-Through capability. This paper utilizes the kinetic energy of the wind turbine generators...
This paper presents an analysis and new fault mitigation methods of grid integration of offshore wind farms and oil & gas installations using Voltage Source Converter (VSC) HVDC transmission system. On the fault occurrence in the onshore AC grid, the proposed DC link voltage controller initiates fast output power drop of the wind farm, in order to avoid the overvoltage in the DC transmission link...
Large and distant offshore wind power plants can be efficiently connected to the onshore power grid network using VSC-HVDC (Voltage Source Converter based HVDC) transmission. Chopper controlled resistors can be used to limit the DC line over-voltage when there is a fault on the onshore AC grid and power transfer to the grid is obstructed. Considering the development of full scale converter based wind...
A multi-terminal voltage source converter based high voltage DC transmission systems (MTDC) was used for grid-connection of large offshore wind power generation. The design of a control system was discussed. A four-terminal system was built to test the control idea. Simulation using PSCAD/EMTDC has been carried out under various load and fault conditions.
