| Abstract | This paper presents an innovative method for the placement optimization of power system measurement. The goal of the method is to minimize the number of necessary measurements and required remote terminal units (RTUs), subject to the system observability requirements. Three types of measurements are considered: bus voltage magnitude measurements, branch power flow measurements and bus injection power flow measurements. A fast algorithm for building up the spanning tree in the observability analysis is developed and applied for the measurement placing process. The algorithm consists of two steps. First, the branch power flow and bus voltage magnitude measurements are placed. The spanning tree of the network is selected by choosing the branches that are connected to the buses with large numbers of incident branches. Once the spanning tree is decided, branch power flow measurements are placed on its branches and installed into as few substations as possible. A voltage measurement is also placed in a substation that already has at least one branch measurement installed. Second, the bus injection power flow measurements are placed in selected substations to backup the branch measurements and add up to the robustness of the measurement placement scheme against the loss of observability. The proposed method can be used as a very helpful tool in planning power network measurement systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
