Research On Fast Solution To System Of Linear Equations In Power System

Bus impedance matrix has a very important role in the calculation and analysis in the power system, which is widely used. And it is the core foundation of various calculation in power system. On the basis of long-term research to the traditional sparse symmetric matrix technology used in power system calculation, we put forward new sparse symmetric matrix technology that used in Gauss elimination method, Gauss-Jordan elimination method, triangle decomposition method, factor table method to solve the linear equation fast. It is mainly aimed at the matrix operation in large power system and clever innovative use of symmetry and sparse feature of the matrix. Effectively avoid the calculation of a large amount of unnecessary elements and increase efficiency of the operation, save computation time. Through the new calculation method and the traditional methods of power system operation time of comparison, it proves the efficiency and feasibility of new sparse symmetric technology. The project completion will significantly improve the speed of the related calculation in power system. It provides a new train of thought To various online calculation of power system(real-time calculation) and to improve the real-time monitoring and the safety reliability of the power system.
