Due to the fault ride-through control strategy, voltage withstand capability, and reactive power / voltage control strategy of wind turbines, the DC transmission capability is greatly restricted, and the transient characteristics of wind turbines and dynamic reactive power compensation devices are mutually coupled, which makes the reactive voltage control characteristics of DC near zone more complicated. In order to effectively solve the problem of transient active support for large-scale wind power grid connection, it is urgent to carry out research on the voltage and power active support technology for the transient process of wind turbines, master the key technologies of active support control for the transient process of wind power and promote the active support of transient wind power. This study may provide a good reference to obtain advances in power grid technology, ensure the safe and stable operation of large-scale wind power grid-connected systems, improve the grid's ability to accommodate wind power, increase the international core competitiveness of key wind power technologies, and promote the scale and sustainable development of wind power industry in China. |
