STEADY STATE OF A SYNCHRONOUS MACHINE IN A BOND GRAPGH APPROACH

摘要

The determination of the steady state of nonlinear systems can be relatively difficult, especially when a considered nonlinear system has many dynamics, there are many iterative process solving this problem numerically as the Newton-Raphson method, this type of process can have a heavy work computationally speaking. The utilization of the bond graph techique is with the purpose to reduce the order of the system. The first step is to obtain a Bond Graph in an integral causality assignment (BGI) then a Bond Graph in a derivative causality assignment (BGD) can be gotten. Hence, the BGD will be less complex by solving with any iterative process. A methodology and a new junction structure to get the steady state of a class of non-linear systems are proposed. This junction structure will have the storage elements in a derivative causality assignment. The proposed methodology is applied to a synchronous machine.
