Abstract

The connection of new installations, as wind power plants, into the public grid requires that some conditions are fulfilled. Their aim is among others to ensure a proper power quality in the grid and to ensure a high probability of electromagnetic compatibility. The harmonic emission of individual sources is one of the power quality concerns, because they can damage and increase heating in devices. However, as there are other power electronics loads are connected, the correct assessment of the harmonic emission from one specific source is not straightforward. in this paper, a review of the most used methods for harmonic emission determination is presented and some considerations are discussed regarding their use in wind power plants harmonic contribution. Depending on the application, one method is more suitable than the other. However, assumptions are necessary with any method, especially for the harmonic impedances. For wind power plants not all the presented methods are suitable. Also, further investigations are needed to determine the harmonic impedance of the wind power plant and public grid, especially around resonant frequencies.

风力发电厂谐波排放的几种测定方法

新设备，如风力发电厂，接入公共电网需要满足一些条件。他们的目标是确保电网中适当的电能质量，并确保高概率的电磁兼容性。单个源的谐波发射是电能质量问题之一，因为它们会损坏设备并增加加热。然而，由于有其他电力电子负载连接，从一个特定的源谐波发射的正确评估是不直接的。本文综述了目前常用的谐波排放测定方法，并对其在风力发电厂谐波贡献测量中的应用进行了讨论。根据应用的不同，一种方法比另一种方法更合适。然而，任何方法都需要假设，特别是谐波阻抗。对于风力发电厂来说，并非所有的方法都适用。此外，还需要进一步研究确定风力发电厂和公共电网的谐波阻抗，特别是谐振频率附近的谐波阻抗。
