摘要
智能变电站采用以太网传输采样值、开入量及参数配置信息,网络通信性能直接影响保护装置运行的稳定性和可靠性。智能变电站现场调试和现场检修过程中,网络通信故障通常缺乏有效测试和定位手段。本文首先介绍智能变电站网络通信的测试机理,然后分析智能变电站网络通信典型故障形态,最后针对其网络数据流特征提出一种基于大规模现场可编程门阵列技术的实施方案。试验表明,该方案满足智能变电站网络通信测试基本要求,可有效提升智能变电站网络系统运维能力。
Intelligent substation uses Ethernet to transmit sampling values, binary input and parameter configuration information. Network communication performance directly affects the stability and reliability of the protection device. In the process of on-site debugging and on-site maintenance of intelligent substation, network communication failure usually lacks effective means of testing and fault location method. This paper first introduces the test mechanism of network communication in intelligent substation. Then, typical failure modes of network communication in intelligent substation are analyzed.Finally, an implementation scheme based on large-scale field programmable gate array technology is proposed for its network data flow characteristics. The test results show that the method meets the basic requirements of network communication test in intelligent substation and effectively improves the op-eration and maintenance capacity of the network system in intelligent substation.
