Abstract

The invention discloses a micro-grid semi-digital semi-physical real-time simulation system based on RT-LAB. An RT-LAB simulation machine comprises a micro-grid module and primary equipment modules located below the micro-grid module, the micro-grid module is connected with each primary equipment module, each primary equipment module is connected with a corresponding first-level control module, all the first-level control modules are connected to a second-level control module, and the second-level control module is connected with a computer; the first-level control modules, the second-level control module and the computer are connected through a switch, so an Ethernet network is formed. The micro-grid semi-digital semi-physical real-time simulation system can be used for simulating dynamic characteristics of a micro-grid and simulating a control method and has good flexibility, the RT-LAB simulation machine is used for simulating primary equipment of the micro-grid, dynamic simulation, verification and extension of photovoltaic power generation, wind power generation, diesel power generation and other micro-grid models can be conducted any time any where, and the micro-grid semi-digital semi-physical simulation system high in universality is formed.

Description

technical field [0001] The invention relates to a micro-grid simulation system, in particular to an RT-LAB-based micro-grid half-digital half-physical real-time simulation system, which uses industrial-grade simulation tools to simulate the micro-grid. Background technique [0002] With the development of the national economy, the electric power industry continues to grow, the power system is also gradually large, and its operation is more complicated. In order to ensure the reliable, safe and economical operation of the power system, the static and dynamic characteristics of the actual power system must be accurately and completely investigated when planning, analyzing and studying the power system. However, traditional analysis methods are difficult to accurately describe these characteristics and predict future accidents. At the same time, the particularity of the power system itself determines that it is difficult to use experimental methods to realize system analysis, ...
