Control Design Strategy to Enhance the Fault-Ride-Through Capability of VSC-HVDC Transmission System Interconnecting Offshore Wind Power Plant
Most of the wind power plants currently installed at North Sea are near to shore connected with the onshore grid through AC cable. AC transmission technology is proven and reliable, but there will be a need to switch from AC to DC transmission since large number of offshore power plants at longer distance to shore are expected to be installed by the end of 2020. Furthermore, to enhance the inte...
متن کاملIntelligent Controller Based Improved Fault Ride-through Capability of Hvdc System Connected to Weak Ac Grid
In the paper, a novel HVDC transmission system operating with weak ac system has been modeled with speed and precision & analyses the control strategy & performance of system, which is controlled using fuzzy. The system can feed a weak or even dead network under fluctuations and big variations of the input power. The fuzzy logic-based control of the system helps to optimize the efficiency of th...
متن کاملCoordinated Control Strategies of VSC-HVDC-Based Wind Power Systems for Low Voltage Ride Through
The Voltage Source Converter-HVDC (VSC-HVDC) system applied to wind power generation can solve large scale wind farm grid-connection and long distance transmission problems. However, the low voltage ride through (LVRT) of the VSC-HVDC connected wind farm is a key technology issue that must be solved, and it is currently lacking an economic and effective solution. In this paper, a LVRT coordinat...
متن کاملInvestigation on Fault-ride Through Methods for VSC-HVDC Connected Offshore Wind Farms
Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage direct current (HVDC) transmission is a favorable opt...
متن کاملImpact of VSC faults on dynamic performance and low voltage ride through of DFIG
A doubly-fed induction generator’s (DFIG’s) sensitivity to external faults has motivated researchers to investigate the impact of various grid disturbances, such as voltage sags and short circuit faults, on its low-voltage ride-through (LVRT) capability. However, no attention has been paid to the impact of internal faults in voltage source converters (VSCs), that interface a DFIG with the grid,...
