基于RTLAB虚实结合的馈线自动化测试OA

In view of the function test of feeder automation,in order to avoid the adverse impact on the safe op-eration of power system caused by the test experiment of distribution terminal connecting to the actual distribution net-work,and to improve the flexibility,efficiency and correctness of the test,a virtual and real feeder automation test method is proposed.The RTLAB(Real Time Laboratory)real-time full digital simulator is used to build the distri-bution network and simulate the fault operation.A simulated virtual distribution terminal with protection,recloser and in-place FA(Feeder Automation)functions is designed to carry out the RTLAB real-time simulator and physical model hardware simulation research.An interface implementation scheme based on high performance linear power amplifier is designed to form a closed-loop access test system for the measured distribution terminal,and an auto-matic simulation test environment combining virtual and real is constructed.The accuracy of the interface device and the effectiveness of the test platform are verified through the hardware-in-the-loop simulation experiment of the basic fault handling capability test and fault tolerance capability test.
