With the ever increase of the penetration rate of wind power in the distribution grid

the issue of voltage quality of grid connection of wind power is not neglected. In this paper

the influence factor of distribution power

in case of connecting to the distribution grid

to the power voltage impact is analyzed firstly. Then

the operation feature of wing power connection and the influence feature of voltage of distribution grid are simulated and analyzed based on PSCAD software and with combination of the 13- node calculation example of distribution grid. Finally

as for the unfavorable influence due to connection of wind power to the distribution grid is given

including appropriate selection of instal-lation capacity

of connection position and mode of wind power

of load switching

capacitor and dyn-amic reactive power compensation equipment.
