| Abstract: | This paper presents a new concept of linear dependent loop on the analysis of the linear relations of meter vectors to resolve the problems of power system observability systematically. Some theorems of this concept are also given. Based on this concept, some efficient algorithms, such as direct analysis of matrix H, super bus operation, numeric & topologic combination, are developed to meet the need of real time analysis of system observability determination. Furthermore, such problems as meter backup, system safety, and optimal meter placement can also been resolved well by the application of linear dependent loop concept. |

| Keywords: | linear dependent loop general minimum spanning tree combination of numeric & topologic method meter backup optimal meter placement |
