This paper expounds the importance and complexity of power line carrier communication （PLC） technique. Test simulation system is established for low voltage PLC by distributed mode. This system breaks through the existing concept of centralized test, reflects the actual running condition, and conducts the comprehensive test on the features of low voltage PLC. Distributed test architecture is characteristics of the simulation system, not only the performance indicators can be tested, but also the routing topology of PLC system and the received signal quality of the communica- tion products. Simulated environment laboratory is established to imitate PLC scenes of various operating conditions through impedance matching. Regular changing laws of routing and received signal quality of PLC can be mastered. This test simulation system can provide a scientific basis for inspecting PLC system and quality of PLC products.
