摘要
本文首次提出了一种求解电力系统中铁道电气化所引起的谐波计算方法,它比较准确地给出了国产韶山Ⅰ型(SS1)电力机车及铁咯牵引网的数学模型,考虑了牵引变电所的不同接线方式,并利用电力系统的数学模型,组成了全系统的数学模型,采用高斯-赛德尔方法迭代求解。本方法可以用研究SS1型电力机车的谐波电流,同时可以计算电力机车在电力系统中造成的负序分量、各次谐波电压及谐波电流。算例结果证明了该方法的有效性。
A computation method for harmonics caused by electric locomotives in power systems is presented in the paper which gives accurate mathematical models for the type -ssl locomotive and traction network with taking d:fferent connecton of traction transformer into consideration. The whole system eguation is then established amd the Gauss-Seidel iteration method is used to solve the eguation. The proposed method can be used to Study the harmenic current of the type—SSI locomotive and to calculate the positive and negative scguencc of harmonie valtage and current componcnts in powor system caused by thc locomotives. The results from a test systen illustrate the effectiveness of the method.
