Parameter Identification of Asynchronous Load Nodes

Asynchronous loads (AL), because of their low negative-sequence resistance, produce the effect reduced unbalance at connection points. Therefore, proper modeling unbalanced load flows in power supply systems requires properly accounting for AL. Adequate models induction motor can be realized phase frame reference. The effective use such is possible only if accurate data on parameters equivalent circuits positive and negative sequences are available. Our analysis shows that techniques used to determine these basis reference yield markedly disparate results. It overcome this difficulty by applying parameter identification methods paper proposes a technique individual motors asynchronous nodes. results computer-aided simulation allow us conclude using identification, we obtain an model node, provides high accuracy both balanced flow analysis. By varying parameters, demonstrate proves valid over wide range values. We have proposed nodes with loads, including electrical drives equipped static frequency converters. With aid AL paper, it solve following practical tasks management electric systems: increasing operating conditions; making informed decisions when taking measures reduce grids while balancing adjustment
