广域继电保护与传统继电保护的探究

Wide-area protection and study of traditional relay protection

继电保护是电网安全的首道防线,对其进行研究意义重大。通过对继电保护的现状及传统继电保护在系统运用中遇到的问题进行分析,并分别对广域继电保护原理进行论述,在此基础上,探究广域继电保护在结构上的分类,并对其算法进行深入研究。通过总结广域继电保护和传统继电保护的特点,对它们的功能做出定性区分。结果表明:传统继电保护在保护对象、适应能力等方面有很大不足,而广域继电保护以其自身在电力、计算机和通信方面的优点正在逐步成为电网保护的新宠。

The security of power grid relay protection is the the study. Through the status of relay protection and traditional were analyzed, and respectively of wide area protection principle first line of defense power grid security,is of great significance to protection relay in the system application encountered problems are discussed, on this basis, to explore the wide area relaying pro- tection in the structure of classification and the algorithm were studied. By summarizing the characteristics of wide area relay protection and traditional relay protection, the function of them is qualitatively distinguished. The results indicate that the traditional relay protection in the protection of the object, adaptability, etc. there is a great shortage, and wide area relaying protection by itself in power, the advantages of computer and communications is gradually becoming the new darling of the protection of the electric grid.
