The solution of the bordered linear systems required in Newton’s method to solve the minimally extended system was realized by block elimination algorithm,thus sparsity of Jacobian matrix of power flow equations could be fully exploited to enhance calculation efficiency.

The paper analyzes the parallel algorithm design schemes for a new architecture of supernodes,discusses different methods of data distribution and task partition in detail,gives an example,namely the blocked Gauss Elimination algorithm,and points out how to develop parallel algorithms for supernodes based on the existing shared and distributed algorithms.

In order to handle this problem,which will cost much CPU time and memory room if only using one CPU to do it, the parallel multisection recurrence algorithm is adopted by using several CPUs to get the ground state energy of Helium atom at the same time.

Power Quality in harmonic and inter-harmonic online rapid detection methods become increasingly concerned about this window interpolation based on the theory of fast Fourier transform spectrum analysis,according to the power system harmonics and inter-harmonic characteristics,the"elimination"of harmonic harmonic detection.
