变压器微机保护的IEC61850改造研究
Research on IEC 61850 transformation of microcomputer-based transformer protection
摘要
Abstract
It is necessary to update the traditional microprocessor-based protection device to meet IEC 61850 in the transformation of digital substation. Taking the transformer protection as an example, this paper adds communication module to original hardware to realize network function. In the software, transformer functions are decomposed and identified by corresponding logic nodes; gas protection logic node class PGAS. Which is not defined in IEC 61850. Is newly developed; implementation process of differential protection is concretely analyzed; finally IEC 61850 server model is constructed, thus completing IEC 61850 data modeling of microcomputer-based transformer protection, which meets IEC 61850 standard. The transformation is simple,cheap and adaptable to current digital substation, with good reference significance and application value.关键词
