Abstract:
Nowadays, many countries are developing renewable energy sources due to the concern of sustainability and pollution of conventional fossil fuels. Wind power has been a major part in the renewable energy market, especially in Europe. In large offshore wind farms, the grid connecting wind turbine converters and the offshore high-voltage dc (HVDC) station is dominated by converters. The fault currents in such a grid have great distinction from that in a conventional grid supported by synchronous generators (SGs) because of the limited overcurrent capability and highly controlled fault currents of converters. As a result, the commonly used protection devices like relays and circuit breakers may have limited functions and even maloperations under such circumstances. Thus, this project aims to develop methodologies to robustly integrate the protection and control of wind turbines as well as the grid interface, under the wide-ranging wind speeds and diverse fault conditions.
The study will, by means of analytical methodologies and simulation tools, perform 1) analysis of fault currents of wind turbine converters and the offshore HVDC station under faults in the offshore ac grid, 2) development of benchmark offshore network with commonly used protection methods, and 3) design of coordinated control and protection of wind turbine converters and the offshore HVDC station.
