中国配电自动化的进展及若干建议

Development of Distribution Automation in China and Some Suggestions

总结了近年来配电自动化技术方面的进展,主要包括:配电自动化主站通过符合IEC 61968标准的信息交互总线与其他信息系统交互;成熟可靠的故障处理策略并具有必要的容错能力;广泛采用以太网无源光网络(EPON)、工业以太网、通用分组无线业务(GPRS)、WiMax、电缆屏蔽层载波等通信技术;采用超级电容器作为其备用电源的储能元件。论述了配电自动化系统测试技术的重大突破,即通过模拟各种故障现象和场景,测试配电自动化系统的故障处理性能。对于配电自动化技术的进一步发展提出了3条建议:继电保护与配电自动化协调配合;借助配电自动化提高配电网供电能力;借助配电自动化提高配电网应急能力。

The development of distribution automation（DA） in China is summarized including the information integration by the IEC 61968 based enterprise service bus（ESB）;the well-developed and robust fault location,isolation and restoration program;wide application of the advanced communication technologies,such as Ethernet passive optical network（EPON）,general packet radio service（GPRS）,WiMax,etc;super-capacitor based back-up supplies for terminal units.The progress in the test of the distribution automation system（DAS） is described,which can evaluate the fault location,isolation and restoration property of a DAS by simulation of various fault scenarios.Three suggestions are given,namely,coordination between relay protection and DA,improvement of the capacity of distribution grids by DAS,and enhancement of the ability to handle the emergency situations by DAS.
