Abstract

Abstract: In view of the high cost of land requisition for urban substations and the increasing demand for power supply reliability of distribution networks, a concept of independent secondary device integrated center (ISDIC) is proposed to realize the compactness requirements of substations and improves the performance of the existing distribution network protection schemes. In order to realize the normal protection function between the center and the substations after change of the protection topology, the site selection for the ISDIC is particularly important, and multiple factors should be considered comprehensively. For this reason, an optimal site selection model is built for the ISDIC by combining the conventional substation site selection schemes and the specific center requirements, which mainly considers such three factors as information delay, resident influence and load distribution. Taking the simple topology of a substation in a city’s urban area as an example, the effectiveness of the model is proved. Firstly, the possible interval of the optimal solution is calculated with the improved artificial bee colony algorithm; and then the ISDIC site node that is most suitable for the center is obtained through precise calculations; and finally the practical engineering significance of the model and the superiority of the method are fully illustrated through analyzing the indexes of the optimal node.
