Technical and Economic Evaluation Model of Organic Insulated Tubular Busbar Transmission Conductor

Abstract

organic insulated tubular busbar with its excellent technical performance in the low-voltage power of distribution system has been amply augmented. But in China its service life is rather short, the technical and economic evaluation of insulated tube bus lacks relevant research, which brings some obstacles to the promotion and use of it. Therefore, in this paper, a technical and economic evaluation model of insulated tube busbar based on conductor technical and economic evaluation index is proposed. Based on the theory of system dynamics, this paper studied the conductor decision factors of intrinsic excitation and external excitation. And the mutual coupling relationship among different conductors are considered. Then, compared with the traditional evaluation indicators of busbar, an index system of system-component of busbar, which can comprehensively reflect the technical and economic level of the conductor, is established. The index system has the function of evaluation and decision-making. The evaluation results show that the technology advantages of the insulated tube busbar can be transformed into the benefit of the system operation under the condition of large-scale use.
