Example Embodiment
[0037] The preferred embodiments will be described in detail below with reference to the accompanying drawings. It should be emphasized that the following description is exemplary only, and is not intended to limit the scope of the invention and its application.
[0038] figure 1 It is a flow chart of a mode-based voltage control method for a wind farm cluster provided by the present invention. figure 1 , the method specifically includes the following steps:
[0039] Step 1: Obtain the real-time voltage V of each wind farm grid connection pointi , the cluster control center will connect the real-time voltage V of the wind farm to the grid i and the voltage target value V issued by the dispatch center i-ref For comparison, set the allowable voltage fluctuation range to be V D ;if |V i -V i-ref |≤V D , no voltage adjustment is performed; if |V i -V i-ref |>V D , then go to step 2;
[0040] Step 2: Calculate the current adjustable reactive power capacity of each wind f...
