Increasing the technological developments of smart sensors, Information and communication tools (ICT) the traditional electric power systems have emerged with the improvement of Smart grids. Smart grid is defined as a modernized electric power grid with the integration of ICT tools and distributed generation (DG) resources into existing power system to provide continuous, stable and quality of power to all. Present smart grid electric power system network, the fault identification and mitigation is one of very critical task. Current power system structure transformed remarkably due to extension and integration of enormous amount of DG resources at delivery side. To confront the limitations of smart grids, existing fault identification and mitigation methods requires immoderate revision by making use of excellent facilities and tools. That will be useful to attain automation in fault detection, enhance the voltage stability, transient stability, and self-healing ability to perform the desired task. This paper is going to presents a detailed survey about target on various types of faults and fault detection methods in smart grids.

随着智能电网的发展，传统的电力系统已经出现，随着智能传感器，信息和通信工具（ICT）技术的发展。智能电网定义为现代化的电网，它将ICT工具和分布式发电（DG）资源集成到现有的电力系统中，从而为所有人提供连续，稳定和优质的电力。在当前智能电网电力系统网络中，故障的识别和缓解是非常关键的任务之一。当前的电力系统结构由于交付侧大量DG资源的扩展和集成而发生了显着变化。为了应对智能电网的局限性，现有的故障识别和缓解方法要求使用出色的设施和工具进行适度的修订。这对于实现故障检测的自动化，增强电压稳定性，瞬态稳定性和执行所需任务的自我修复能力将非常有用。本文将针对智能电网中各种类型的故障目标和故障检测方法进行详细的调查。
