UPFC最优布点问题研究

An Investigation into the UPFC optimum arrangements

UPFC元件作为一种功能强大的FACTS器件正日益受到广泛的研究和重视，并有望在未来几年内投入实际运行。就其在应用中首先面临的问题即安装地点问题进行研究，在限定UPFC个数的情况下，以总容量成本最小为目标，通过目标潮流寻求电力网络中的最优环路集，并以其中的最佳连支作为UPFC的最佳安装地点。

UPFC elements, the most powerful FACTS devices increasingly widely studied and seriously taken, are expected to be put into operation in a few years. The first problem in its application,i. e. the installation place, is discussed in this paper. In case the number of UPFC is limited and the minimum capacity cost is taken as an objective, the optimum sets of loops for power network can be found through objective power flows. Then the optimum shunt circuit is the best place for the UPFC installation.
