Problems solved by technology
[0007] First of all, the current modeling of online temperature monitoring of smart substation equipment has not eliminated the defects of locality, dispersion and isolation of information obtained from each temperature monitoring point
[0008] Second, with the support of the IEC61850 standard, it is impossible to uniformly model the information of each temperature monitoring point into IEC61850 standardized information, and it is impossible to build an integrated information platform for smart substations

Description
technical field [0001] The invention relates to a model for online temperature monitoring of intelligent substation equipment in the field of power transmission and distribution. Background technique [0002] At present, the State Grid proposes to build a strong smart grid with informationization, digitization, automation, and interaction as the basic technical characteristics. As an important foundation and support for a unified and strong smart grid, smart substations are an indispensable construction for the realization of smart grids. content. [0003] Smart substations require the construction of a unified information communication platform. The devices in smart substations must be interoperable, and the interfaces, protocols, and data models must be compatible. It is an inevitable trend of technology development for smart substations to choose the IEC61850 standard as the basic communication protocol. [0004] Although the role of auxiliary equipment has become more p...
