| Abstract | When a power system load parameter is over a certain value, the system will experience a saddle-node bifurcation, and voltage collapse occurs. The difficulty in getting the voltage collapse point is that the system Jacobian matrix has a simple zero eigenvalue at the critical point, causing the Newton method failure in the neighborhood of the bifurcation point. Based on the circuit models of a power system and the theory of manifold transversality, the saddle-node bifurcation point is corresponding to the non-transversal intersection between the solution manifolds of injection equations and the linear network equations in the space spanned by the bus voltage and the injection current. This research studies the characteristics of the two solution manifolds and gives an algorithm based on the Newton algorithm for getting the non-transversal point, and it also can calculate the transversal point |

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.
