变速风力涡轮机在网络中注入谐波电流，这可能潜在地产生电压失真问题。在本文中，一个10兆瓦的风力发电场，打算连接到一个网络与扩展的高压海底电缆线路的案例研究。首先，系统建模方法和谐波潮流计算进行了说明。然后，系统的谐波阻抗计算的各种配置和操作条件下，其主要特点进行了讨论。提供谐波潮流计算以指示潜在的电压失真问题。一个简化的方法，建议在相关的IEC出版物，适用于该系统，其结果进行比较的谐波潮流。还讨论了风电场内谐波电流的求和问题
Variable-speed wind turbines inject harmonic currents in the network, which may potentially create voltage distortion problems. In this paper, a case study is presented for a 10-MW wind farm, intended to be connected to a network with extended high-voltage submarine cable lines. First, the system modeling approach and the harmonic load-flow calculation is described. Then, the harmonic impedance of the system is calculated for a variety of configurations and operating conditions, and its main characteristics are discussed. Harmonic load-flow calculations are provided to indicate potential voltage distortion problems. A simplified methodology, suggested in relevant IEC publications, is applied to the system and its results are compared to those of the harmonic load flow. A discussion on the summation of harmonic currents within a wind farm is also included
