A method for effective utilization of power distribution apparatus in an industrial park by looping distribution lines is proposed. The proposed method uses a series type Back-To-Back (BTB) converter in loop distribution line. This method solves the problem of heavily-loaded and lightly-loaded lines condition in distribution line autonomously. The problem of heavily-loaded and lightly- loaded lines results in lower utilization of transformers and increases losses in electricity system of the industrial park. By employing this proposed method, effective utilization of apparatus is realized by minimizing circulating current and balancing power of transformers in loop distribution line. One of the major characteristics of the proposed scheme is that the required converter capacity is small and it can be installed close to the transformers in loop distribution line. Analysis and simulation results to validate the proposed method are presented in this paper.
