基于IEC 61850的微机馈线保护IED模型的建立

Modeling of microcomputer-based feeder protection based on IEC 61850

IEC 61850标准是当前变电站自动化系统通信的研究热点,而实现IEC 61850标准通信协议的核心内容之一,是必须要在变电站内的IED中建立遵循IEC 61850标准的数据模型。文章以微机馈线保护装置为例,主要介绍了常规微机馈线保护所配备的功能,并将这些功能分解为IEC 61850中定义的逻辑节点,然后按照IEC 61850规约提供的模型来对分解的功能进行建模,最后采用XML语言对建立的IED模型进行了描述。

Nowadays, IEC 61850 is the hot point of substation automation communication, and the one of core works of implementation of IEC 61850 communication protocol is building the data model of IEDs in substation according to IEC 61850 standards. This paper introduces the functions of microcomputer-based feeder protection, and decomposes these functions into a logic defined in IEC 61850-node, then modeling the function of decomposition in accordance with the IEC 61850 model. The IED model using XML language is also discussed in the paper.
