能源互联网继电保护研究与展望

A Survey on Wide-Area Backup Protection in Energy Internet

能源互联网的建设为继电保护领域的发展提供了机遇,然而传统继电保护系统在复杂互联的电网保护中已凸显能力的不足。以广域测量技术、通信技术、计算机技术为基础,能源互联网继电保护发展为着眼于全局角度的广域保护。本文通过对能源互联网继电保护与传统继电保护的对比,介绍了能源互联网继电保护的功能、结构,以纵联差动保护为例阐述了能源互联网继电保护的主要特征,并对其未来发展进行了展望。

The construction of energy Internet provides an opportunity for the development of relay pro-tection. However, the traditional relay protection system is inadequate in the complex inter-connected power grid protection. Based on wide area measurement technology, communication technology and computer technology, the energy internet relay protection has developed into a global perspective of the wide-area protection. Through comparison of the energy internet relay protection and traditional protection, the function and structure of energy internet relay protection are introduced, and the main features of the energy internet relay protection are described in the case of the differential protection. Besides, the future development is prospected in this paper.
