    Abstract: On the basis of the large-scale development of wind power current situation in certain area, combining with the concrete cases, this paper studied on the impact of different wind power grid connected methods on the main transformer depressurization power, voltage fluctuation, short circuit and system tide of PCC (point of common coupling), found out the key factors influencing on wind power capacity of grid acceptance and proposed measures to improve the PCC voltage regulation capacity via increasing the reactive compensation of wind power plant. The main transformer capacity and load in substation were increased to enhance the grid structure etc measures to raise the PCC wind power capacity of grid acceptance to provide references for the following wind power access system design.
    Key words: access grid; point of common coupling; power balance; voltage fluctuation
