Plug-and-play unit cabinet for intelligent power grid experiment training based on grid framework

Abstract

The invention relates to a plug-and-play unit cabinet for intelligent power grid experiment training based on a grid framework, which comprises multiple unit cabinets, wherein each unit cabinet forms an m*n array; the m and the n are integers; each unit cabinet is provided with a primary system module, a secondary measurement and control module and a communication module; the primary system modules are provided with primary electric interfaces; the unit cabinets are connected with the adjacent unit cabinets and the secondary measurement and control modules through the primary electric interfaces; the secondary measurement and control modules finish measuring the current of each wire and the voltage of each bus in the primary system modules and controlling a breaker and convert the voltageand current of the primary system modules into the secondary voltage and the current which are consistent with an actual system and transmitted to a monitoring center; and the communication modules realize the mutual real-time communication among the monitoring center, the unit cabinets and the other primary and secondary equipment through different communication channels and are accessed to the communication network of the system through the standard communication interfaces of the communication modules of the unit cabinets, thereby realizing the communication function with each unit cabinetand the monitoring center.

Description

technical field [0001] The invention relates to a grid-based plug-and-play smart grid experimental training unit cabinet. Background technique [0002] The power system physical simulation system is a physical model established according to the principle of similarity and has the same physical properties as the prototype power system. , protection and other analog devices. The power system physics simulation system has the following characteristics: [0003] 1. You can directly observe all the physical processes of the research subject in the power system on the model, obtain a clear physical concept, and conduct qualitative research on the characteristics and processes of the power system very conveniently. [0004] 2. For problems that cannot or cannot be well described by mathematical equations, physical simulations can be used to explore the physical nature of the problems, and the rationality and correctness of existing theories and teaching simulations can be verifie...
