摘要
传统的配电系统本质上是径向的,并通过一个主电源供电。这些网络有一个非常简单的保护系统,通常使用熔断器、再闭合器和过流继电器来实现。近年来,分布式发电在配电系统中的应用受到了广泛的关注。在电网中存在这样的发电机组,会导致保护装置失去协调。因此,需要有一种能够通过诊断和隔离发生的故障来保护包括DG在内的配电系统的算法。本文提出了一种新的配电网络保护方法。该算法基于将现有配电网划分为几个区域;每一艘都有能力进行孤岛作战。该方案已在伊朗大城市设拉子的部分实际配电网中实施,并对方案的性能进行了测试。配电网仿真和继电器算法实现分别使用了DIgSILENT Power Factory 13.2和MATLAB。
Implementation of a New Protection Scheme on a Real Distribution System in Presence of DG
Conventional electric distribution systems are radial in nature, and are supplied through a main source. These networks have a very simple protection system which is usually implemented using fuses, re-closers, and over-current relays. Recently, great attention has been paid to applying distributed generation (DG) throughout electric distribution systems. Presence of such generation units in a network, leads to losing coordination of protection devices. Therefore, it is required to have an algorithm in hand which is capable of protecting distribution systems that include DG, through diagnosis and isolation of occurred faults. In this paper, a new approach for protecting of distribution networks in presence of DGs will be presented. The algorithm is based on dividing an existing distribution network into several zones; each of them is capable of operating in island operation. The proposed scheme has been implemented on some part of a real distribution network in Shiraz which is a large city in Iran and performance of the proposed scheme is tested on it. For simulating the distribution network and for implementing the relay algorithm, DIgSILENT Power Factory 13.2 and MATLAB are used respectively.
