| 摘要: |
| 智能电网的蓬勃发展决定了智能变电站有着广阔的前景。智能变电站在组织结构、网络通信和使用二次设备上与传统的变电站都有很大的不同，使得智能变电站继电保护系统与传统变电站继电保护系统相比有明显优势，同时在数据采集、时钟同步和电磁兼容等方面也存在着一些亟待解决的问题。就地保护概念的提出同时带来了新的挑战。对智能变电站继电保护系统存在的问题进行了讨论。在综述了目前研究现状的基础上，指出了当前研究存在的不足，并对今后的研究方向提出了一些建议和设想。 |

| Abstract: |
| The fast development of smart grid ensures a bright future of intelligent substation. Intelligent substation differs much with the traditional substation in its structure, network communication method and the devices applied, which are all advantages of intelligent substation compared with traditional one. But in the practical operation, it also faces many problems in value sampling accuracy, clock synchronization and electromagnetic compatibility. The new concept “local protection” also brings some problems. The problems above are discussed and the current research results are listed, then the insufficient research points are pointed out and several suggestions and ideas for future research are proposed.
