Abstract | In this paper, a fast harmonic load flow method is proposed for unbalanced radial distribution systems. The proposed method is developed from the commonly used current-injection formulation and forward/backward sweep techniques. By the backward sweep technique, the relations between branch currents and the harmonic sources can be formulated, and then the harmonic voltage of each bus can be solved by the forward sweep technique. The proposed method is more efficient than the conventional harmonic load flow algorithms, since the time-consuming procedure of the Y matrix inverse is not required in the solution procedure. Some applications of the proposed method, such as the frequency scan of driving point impedance at the possible harmonic resonant buses, are also presented in the paper. Test results demonstrate the accuracy and efficiency of the proposed method. |

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.
