国家与周边国家之间的互联互通提供了一个大电网。随着风电技术的进步、风电装机容量的增加，风电对电网的影响也成为重要的研究课题。大型电力系统正面临新的挑战，例如可再生能源（特别是风力发电）的渗透率不断提高、需求不断增长、资源有限以及电力市场竞争激烈。在此条件下，大电力系统面临着电压调节、潮流控制、保护和稳定等重大运行问题。传统的独立（单元）保护方案无法保护大规模电网系统，特别是在发生大扰动后。众所周知，大的扰动可能会引发一系列级联中断，从而导致整个系统停电，并对设备和社会造成灾难性后果。目前采用的用于实现保护的方法在这种配置方面并不是显着的进步。必须将保护和控制方面的进步引入风电场应用领域，以满足这种配置的特定需求和挑战。本文对可再生资源输电线路传统保护技术进行了全面的综述，并指出了该技术的主要缺点。还给出了当今可用于应用和应对此类挑战的保护的最新技术和新趋势。部署在智能电网上的智能设备和基于智能的无线设备可以增强并为应对此类挑战提供新颖的想法。
Interconnection between countries and surrounding countries provides a large power grid. With the improvement of wind power technology, increase of wind power capacity, the impact of wind power on the grid has become an important research topic as well. Large power systems are facing new challenges, such as increasing penetration of renewable energy sources, in particular wind generation, growing demands, limited resources, and competitive electricity markets. Under these conditions, the large power systems have had to confront some major operating problems in voltage regulation, power flow control, protection, and stability. The traditional stand alone (unit) protection schemes are not capable to protect large scale grid system, particularly after large disturbances. As it is known large disturbances might provoke a series of cascading outages, which can lead to the total system blackout and catastrophic consequences to the equipment and society. Current approaches adopted for implementing protection are not significant advancement in such configuration. Advancements in the protection and control have to be brought into the domain of wind farm application to address the specific needs and challenges of this configuration. This paper introduces a complete survey about traditional protection techniques for transmission line connected with renewable resources and the main shortcoming points for such techniques. Also the most recent techniques and new trends of the protection available nowadays for applying and facing such challenges are given. Smart devices deployed on the smart grid and smart based wireless devices can enhance and provide novel ideas for facing such challenges.
