摘要
介绍了换流阀损耗和换流变压器损耗的计算方法。根据IEC61803中的损耗计算模型,采用时域分段法计算谐波,开发出换流站损耗分析软件。换流站损耗算例分析显示,用时域分段法精确算得的谐波电流对直流侧换流阀及平波电抗器的损耗计算值影响不大,但对交流侧的换流变压器损耗计算值影响则较明显。
The calculation methods for power losses of thyristor valve and converter transformer are introduced. According to the models in IEC 61803, an analysis software for power losses in HVDC converter stations is developed, which is based on a time domain piecewise method for harmonic current calculation. A calculation example of power losses in a converter station is analyzed, showing that the harmonic current value calculated with the time domain piecewise method has little impact on the loss values of thyristor valve and smoothing reactor in the DC side, but marked influence on the loss value of converter transformer in the AC side.
