风电场装机容量与配电网短路容量的关系

Relationship between Wind Farm Capacity and Short-circuit Capacity of Distribution System

风电场接入配电网引起的电压偏差不仅由风电场装机容量与配电网接入点的短路容量之间的比值K值决定,还与配电网阻抗角及风电场功率因数有关.通过具体算例的计算,给出不同情况下接入配电网的风电场的最大装机容量的建议.

This paper demonstrates that the voltage variation caused by the wind farm not only is due to the relationship between the wind farm capacity and the short-circuit capacity of the distribution system,but also depends on the impedance angle and wind farm power factor.In addition some recommendations are suggested for determining the wind farm capacity under different circumstances via a simple case study.
