Abstract:

In view of the function test of feeder automation, in order to avoid the adverse impact on the safe operation of power system caused by the test experiment of distribution terminal connecting to the actual distribution network, 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 distribution 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 automatic 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.

Key words: feeder automation, RTLAB, combination of virtual and real, hardware in the loop, power amplifier, power distribution terminal, interface device, fault test
