| 摘 要： | 本文首先提出了对单个六脉冲换流装置在换流变压器三相漏抗不等情况下的数学模型。以此模型为基础,根据换流站的接线方式并利用直流输电网络的模型,组成整个直流输电系统的数学模型和相应的方程式,然后用牛顿—拉夫逊法求解。本文提出的计算方法,不但能准确地计算由于换流变压器三相漏抗不等而引起的非特征谐波,而且可以同时计及交流系统三相电压不平衡和触发脉冲间隔不相等两个因素。因此这一方法比较完整和准确地解决了非特征谐波的计算问题。

| Abstract: | A .new model of conver ter transformers is presented in this paper considering the unbalance of converter transformers. Based on this model and the models of AC systems and DC transmission line, the whole system equations are obtained and solved by the Newton-Raphan method. The Non-characteristic hamonics solution method for HVDC transmission systems is presented simultaneously considering the imbalance of AC voltages and firing asymmetry. |
