| Popis: | With the increasing wind power penetration, the dynamic behavior of modern power systems changes. Wind turbine generators (WTGs) should provide the ancillary services to enhance the transient stability of the power system. Currently, the installed WTGs are required to equip with the low-voltage ride-through (LVRT) capability based on the grid codes; that is, the WTGs should stay connected to the grid during short-term voltage drops. This paper reviews control stategies of the WTGs for providing the LVRT capability. First, the extra devices for limitating the transient current and voltage in WTGs are introduced. Then, the control techniques for the reactive power support without any additional components are reviewed. This investigation provides useful information to wind turbine manufacturers and grid operators. |
