摘要:
在现代调度中心中需要有效的在线安全分析手段,但是如果电网参数是病态的,就会使得分析计算的迭代不能很快收敛,在时间上造成拖延。这种现象意味着报警不及时和运行水平的低劣。这是当前急需解决的课题之一。本文首先给出一种适用于工程计算的病态识别指标,然后应用一种新的潮流算法,即支路差值解耦潮流算法来识别病态,查找病态的敏感元素,再通过施加某种扰动来促使迭代的快速收敛。对七个电网进行了试算,其中四个通常被认为是病态的,所有算例都证明了本方法是有效的。
Abstract:
This paper presents a simplified index to recognize ill-conditioning for the basic linear equations and power system analysis problems. A new loadflow formulation is then presented. A key advantage of this new decoupled branch difference (DBD) load-flow algorithm is its ability to both recognize the physical parameters causing ill-conditioning, and thereby through a simple procedure to numerically eliminate the ill-conditioning. Test rsults on seven systems, four of which are taken from the literature of ill-conditioned power systems, are presented.
