The Mode Building Of Multiple Lode Flow Solutions And Its Flexible Node Algorithm For Named Operation Solutions In Power System

From the eighties of the twentieth century, voltage stability has been a global focus to research in power engineering and academe. But different researcher sets out from respective study aspect, and has different understanding of voltage stability mechanism. Therefore, voltage stability is still a fresh subject full of challenge and fascination.Under the complicated research background that opinions vary here, there is one view accept by a lot of researchers, the possible multiple lode flow in power system which is a route to study voltage stability. This text under the background of fact that like this, has studing the mode building of multiple lode flow solutions and its flexible node algorithm for named operation solutions in voltage stability calculations. The main research contents are as follows:(1) Considering that has still lacked the mathematics tool that about nonlinear equations set of algebra, the limitation exists yet in the discussion of numerical calculation method whose foundation is the linearization, we have chosen the maximum lode power method as the basis, according the geometric solution about simple AC branch folw fundamental equation's pie chart, to get the characteristic equation h(x, y,t) =0 of various objective physical operational behavior for describing the circuit.(2) To the n nodal network that represented by nodal voltage equation, need to confirm 2n links nodal voltage variable, which should satisfied with 2n nodal power equation, and should meet m desingnated power characteristic equation, it is the mathematics problem that the equation counts more than the variable dimension. But in view of physics , the physical phenomenon is an objective reality that meet the current equation g and the equality constraint condition h at the same time, then it is not separate that current equation g and equality constraint condition h. Utilize their consistent relation, answering can be met the solving of g and h requirement at the...
