摘要

本文提出了一种改进的过流保护系统，以克服并联配电馈线保护的断点。为了实现适当的保护设置，引入了两个概念，并对它们的性能进行了评估。这些概念是利用智能电网信息的自适应协调和改进的协调方法。修正后的协调随当代最坏故障点的变化而调整。对自适应协调概念、修正协调概念和传统协调概念进行了比较研究。为了研究目的，使用Matlab/Simulink软件包对11 kV配电馈线进行建模。结果证明了改进后的并联配电网协调概念的有效性。

Clearing Break Points of Overcurrent Protection Coordination for Parallel Distribution Feeder

This paper presents a modified overcurrent protection system to overcome the break points of a parallel distribution feeder protection. For realizing an appropriate protection setting, two concepts are introduced, and their performance is evaluated. These concepts are the adaptive coordination exploiting smart grid information and the modified coordination methods. The modified coordination is adjusted with changing of the contemporary worst fault point. A comparative study is done between the adaptive, modified, and conventional coordination concepts. For investigation purposes, a 11 kV distribution feeder is modelled using the Matlab/Simulink package. The results provide evidence of the efficacy of the proposed modified coordination concept for parallel distribution feeders.

期刊介绍： International Journal of Energy, Environment, and Economics publishes original research papers that shed light on the interaction between the utilization of energy and the environment, as well as the economic aspects involved with this utilization. The Journal is a vehicle for an international exchange and dissemination of ideas in the multidisciplinary field of energy-environment-economics between research scientists, engineers, economists, policy makers, and others concerned about these issues. The emphasis will be placed on original work, either in the area of scientific or engineering development, or in the area of technological, environmental, economic, or social feasibility. Shorter communications are also invited. The Journal will carry reviews on important issues, which may be invited by the Editors or submitted in the normal way.
