Grid-architecture-based plug-and-play type intelligent power grid experiment training system

Abstract

The invention relates to a grid-architecture-based plug-and-play type intelligent power grid experiment training system, which comprises a plurality of unit cabinets, wherein each unit cabinet forms m*n arrays (m and n are integers), and is provided with a primary system module, a secondary measurement and control module and a communication module; the primary system module is provided with a primary electric interface; the unit cabinet is connected with adjacent unit cabinets and the secondary measurement and control module through the primary electric interface; the secondary measurement and control module is used for measuring current and bus voltage of all circuits in the primary system module, controlling a circuit breaker, converting voltage and current of the primary system module into secondary voltage and current which are consistent with those of an actual system and transmitting the secondary voltage and current to a monitoring center; and the communication module communicates with the monitoring center, the unit cabinets and other primary and secondary equipment in real time through different communication channels, and is accessed into a communication network of the system through a standard communication interface of the unit cabinet communication module. Therefore, a communication function is realized between various unit cabinets and the monitoring center.

Description

technical field [0001] The invention relates to a grid-based plug-and-play smart grid experiment training system. 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 verified, so th...
