A set of voltage differential equations describing electromagnetic transient of synchronous machines is derived from Park-Gorev equations. To solve the equations, the author presents a stepwise method with a solution worked out in analytical form for each step. The equations and the method of solution have been used in the computing program of the transient of complex power system with impact load.
This article is presented out of to the necessity of the acoustic logging of petroleum wells.The system is assumed to be a fluid cylinder surrounded by a uniform quasi elastic solid medium and the acoustic logging tool is simulated by a central rod with local vibrating surface.The two dimension fast Fourier Transform(FFT)algorithm is adopted.Sound fields in rocks of different properties using different source frequencies are calculated and the sound pressure waveform curves on a series of recording points a...
In engineering fracture analysis, random boundary imperfections as notches or cracks are common and important. In this paper, we have worked out a class of methods for solving two-dimensional problems of random boundary notches and/or cracks by an extension of Muskhelishvili's method. Through successive applications of analytic continuation, Laurent series expansion and conformal mapping, we finally arrived at a set of linear algebraic equations governing the problem. Then standard computing progra...
