基于虚拟现实技术的变电站交直流电源仿真设计

Simulation Design of AC and DC Power Supply in Substation Based on Virtual Reality Technology

由于电源结构复杂,需要对变电站交直流电源结构进行分层,导致现实中设计变电站交直流电源分层结构成本高,因此提出虚拟现实技术,仿真设计变电站交直流电源。根据Multigen Creator所创立的变电站实体和场景模型,利用Unity 3D仿真平台实现虚拟变电站各种功能,在变电站三维虚拟场景与各项辅助功能下,构建分层分布结构的变电站交直流一体化电源模型。该电源模型将站用交流电源和直流电源以及不间断电源(UPS)等设备结合进行一体化设计和配置,利用统一智能虚拟平台,实现变电站交直流电源集中管控与供电,并检测电源在线状况。一体化电源模型运行情况及相关信息可以经一体化监控模块显示,同时转换成标准模型数据,利用标准DL/T860格式与当地站控层交换机连接,上传到远程控制中心,实现电源系统控制。经验证,该方法能够有效降低变电站交直流电源设计成本;同时,该方法可应用到变电站交直流电源培训系统仿真设计领域,具有重要的培训应用价值。

Because of the complex power supply structure,it is necessary to stratify the AC-DC power supply structure of substation,which leads to the high cost of designing the hierarchical structure of AC-DC power supply in substation in reality.Therefore,the virtual reality technology was put forward,and the AC-DC power supply of substation was designed by simulation.On the basis of the substation entity and scene model created by the Multigen Creator,the Vega simulation platform was used to realize various functions of the virtual substation.Under the three-dimensional virtual scene and various auxiliary functions of the substation,the integrated AC-DC power supply model of the substation with hierarchical distribution structure was constructed.AC power supply,DC power supply and UPS power supply was used in this power model.Combined with integrated design and configuration,the unified intelligent virtual platform was used to realize centralized control and power supply of AC and DC power supply in substation,and to detect the on-line condition of power supply.Integrated power supply system operation and related information was displayed by integrated monitoring module and was simultaneously converted into standard model data,using standard DL/T860 format to connect with local station control layer switch,upload to remote control center to realize power system control.It is proved that the proposed method can effectively reduce the design cost of AC/DC power supply in substation and has good economic benefits.
