Abstract

The invention relates to the technical field of on-line monitoring, in particular to a monitoring on-line data model mapping method based on IEC 61850. Through the method that an IEC 61850 model and monitoring device plant protocol models are mapped, communication protocol conversion is completed, accessing, storing and transferring of transformer substation on-site on-line monitoring device monitoring data to an integrated monitoring unit are achieved, standard accessing of on-line monitoring data to a station end monitoring unit is completed; according to the on-line monitoring data model mapping method, on the basis that data access interface specifications of monitoring devices of plants are standardized, the mapping method with an event as a center based on an embedded database is used. According to the method, the mapping process of a monitoring data model of a traditional on-line monitoring device to the IEC 61850 data model is completed, efficient unified management of various monitoring devices is achieved, and accordingly working efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring, in particular to an IEC 61850-based on-line monitoring data model mapping method. Background technique [0002] The State Grid Corporation of China has introduced a series of standards, stipulating that the smart substation monitoring unit (CAC) connected to various comprehensive monitoring units (or online monitoring devices that meet the communication requirements of the IEC 61850 standard) must follow the I1 interface specification. At this stage, the monitoring data of the online monitoring device of the substation is connected to the dissolved gas in the oil of high-voltage equipment such as transformers and reactors, and the partial discharge monitoring device meets the requirements of IEC 61850 communication on the basis of comprehensive consideration of the importance and economical factors of the primary equipment. In addition to the standard, the communication of most online ...
