基于IEC61850标准的变压器微机保护建模

Transformer Microcomputer Protection Modeling Based on IEC61850 Standard

提出了一种符合IEC61850标准的变电站内通信系统的变压器微机保护框架模型。以一种变压器微机保护为例,遵循面向对象建模和抽象服务映射的思想,按照IEC61850保护功能对其进行了功能分解,使其分解为功能的最小单位———逻辑节点;对变压器保护相关服务做了介绍,并确定变压器保护服务模型;构建了变压器保护模型,使其符合IEC61850标准。文中所使用建模方法对其它保护设备同样具有较好的参考价值。

With the development of IEC61850 standard, digital substation construction has become practice engineering stage from theoretical research phase. This paper presents a framework model of IEC61850 Standard communication system in the substation transformer microcomputer protection. Based on a kind of transformer microcomputer protec- tion for example, ,following the idea of object oriented modeling and abstraction of service mapping, according to IEC61850 protection function for its function decomposition, the paper makes it into the smallest unit logic node. Re-lated services for transformer protection are introduced and the transformer protection service model is determined the transformer protection model is built to meet the IEC61850 standards. The use of other modeling method to protect the equipment also has a good reference value.
