Discussion on dynamic var compensation scheme of wind power station

摘要

The change of active and reactive output of wind power station is quite random. If no appropriate reactive regulation is adopted, the voltage change of common connecting points will be frequently. After large-scale wind power station has been connected into the power grid, it will not only affect the power quality of the power grid but also endanger the safe and stable operation of the power grid. This paper has made detailed analysis and calculation of mode and capacity of reactive power compensation of wind power station from the angle of voltage control and power factor control and raises a dynamic var compensation scheme which is suitable for wind power station in coastal area of Jiangsu, providing reference for construction and operation of wind power station in other regions.
