基于智能变电站“三层两网”框架标准的仿真培训系统研究

为实现智能变电站的标准化、沉浸式仿真，在“三层两网”框架下建构一种仿真培训系统，根据智能变电站的分层结构，利用PACAD/EMTDC，采用面向对象的建模技术逐个建构IED设备模型，并据此，使用OPNET建立与之对应的通信网络模型，并基于Socket接口进行数据交互，以实现电气与通信的一体化仿真，据此，搭建仿真培训系统的整体框架；引入3D Max建模工具构建IED设备可视化组件，在Unity3D创设的虚拟环境中通过可视化组件的装配，来构建可复用的沉浸式的三维仿真环境。通过实验分析可知，该系统的仿真数值与实测数值之间的误差均在2%以下，且能够适用于不同的仿真培训，具有复用、经济性。

Research on simulation training system based on "Three Layers and Two Networks" framework standard of intelligent substation

In order to realize the standardized and immersive simulation of intelligent substation，this paper constructs a simulation training system under the framework of "three layers and two networks".Firstly，according to the hierarchical structure of intelligent substation，using PACAD / EMTDC，object-oriented modeling technology is used to construct IED equipment models one by one.Based on this，OPNET is used to establish corresponding communication network model，and Socket is used to connec. In order to realize the integrated simulation of electrical and communication，the overall framework of the simulation training system is built；at the same time，3D Max modeling tool is introduced to build IED equipment visualization components.In the virtual environment created by unity3d，the reusable immersive 3D simulation environment is constructed through the assembly of visualization components.Finally，through experimental analysis，it can be concluded that the error between the simulation value and the measured value of the system is less than 2%，and it can be applied to different simulation training，with reusability and economy.
