摘要 由于风电场采用大量逆变设备,将会向电力系统注入过高的谐波电流。目前风电场设计中通常将风机厂家提供的风机输出谐波电流直接通过电压变比换算至高压侧,所得到风电场注入电力系统的谐波电流偏大。本文通过引入变压器谐波模型,在谐波计算中考虑了对谐波电流影响较大的变压器,计算结果更接近实测值,对风电场设计提供参考。

Abstract:As wind farm using a large number of inverter equipment, it will contribute harmonic current to the power system. Presently in the wind farm design, the total harmonic current is obtained by conversion the output harmonic current provided by the manufacturers to the high side voltage ratio, however, the result will be considered higher. The paper introduces the transformer harmonic model to the harmonic calculation, the result is more close to the measured values, provides the reference for the wind farm design.
