Abstract
En 中文
This work presents a new methodology for steady state analysis of multiphase electrical systems, the N Conductor Current Injection Method - NCIM. It is based on the current injection method in rectangular coordinates that is defined directly in phase coordinates and applies the Newton-Raphson method in the solution process. The method can be used to analyze any electrical power system. NCIM has the capability to represent many features, such as unbalances, mutual couplings, multi-phase feeders and devices including neutral conductors and groundings, distributed generations and control actions, in such a way that the total dimension of the system of equations is the minimum required to obtain the solution. The method can be applied to analyze both balanced and unbalanced systems, radial or meshed, and can simulate the interconnected transmission, subtransmission and distribution networks, including large-scale systems. NCIM is shown to be very efficient and computationally robust. (C) 2012 Elsevier Ltd. All rights reserved.
