虚实结合的馈线自动化系统测试平台设计

Testing platform of feeder automation system with the combination of virtual and reality

馈线自动化的实现模式有多种,不可能在真实配电网上进行实验验证。因此,需要设计馈线自动化系统测试平台来对馈线自动化系统进行测试。分析了配电网的仿真需求,采用RTDS搭建配电网模型并对故障进行模拟。提出了利用虚拟配电终端系统来模拟一组配电终端的运行。在虚拟配电终端系统结构设计中提出了基于CIM的拓扑分析技术来解决虚拟配电终端系统对内及对外的数据关联问题。提出了采用虚拟交换技术来解决多个虚拟终端共享一个网口进行数据交换的问题。在上述技术基础上,设计了一套由RTDS、虚拟配电终端系统、真实配电终端和主站系统组成的馈线自动化系统测试平台。最后在平台上进行测试实验,验证了该测试平台的有效性。

There are variety of implementations of feeder automation,which can't be verified on the real distribution network.Therefore,it is necessary to design a testing platform to test the feeder automation system.The simulation requirements of distribution network are analyzed,and RTDS is used to build the distribution network model and simulate the fault.A virtual distribution terminal system is proposed,which is used to simulate the operation of a group of distribution terminals.In the structural design process of the virtual distribution terminal system,a topology analysis technology based on CIM is proposed to solve the problem of internal and external data association,the using of virtual switching technology is proposed to solve the problem of data exchange when numerous virtual terminals share one network port.On the basis of the above technology,the testing platform of feeder automation system is designed,which is constituted by RTDS,the virtual distribution terminal system,real distribution terminals and master station system.Finally,the test experiment is carried out on the platform,which verifies the validity of the testing platform.
