改进直流法在静态安全分析中的应用

Application of the improved direct current load flow algorithm on static security analysis

在电力系统静态安全分析中 ,直流法由于具有简单、快速、便于实时计算等优点而得到广泛应用 ,然而由于其计算精度较差使得计算效果不够令人满意。文中提出了一种改进的直流法来提高直流法的计算精度。通过IEEE的标准算例对该算法进行了验证 ,结果表明所提出的方法是有效的。

The direct current load flow model is broadly applied in the static security analysis in power system because it is simple and easy to calculate rapidly. Unfortunately, it is not so satisfied because of its low precision. One kind of improved direct current load flow model is put forward to improve its precision in the paper. The proposed approach was tested on the standard IEEE14 bus and IEEE30 bus system. The results of simulation show that the method is effective.
