Design of test platform for electricity information collection system based on multi-network fusion technology

In order to build an electricity information collection system with the satisfied communication performance in the smart grid, it is essential to evaluate the communication performance for low-voltage power line carrier communication (PLC), RS485 communication and short range wireless communication used widely in the electricity information collection system. A communication performance test platform based on the multi-network fusion technology is designed in this paper. By comparing the comprehensive assessment value of the communication performance for different communication modes, the optimal communication mode can be selected. The test results indicate that the test platform can effectively evaluate the communication performance of the multi-network and make a choice for the optimal communication mode in the construction process of the electricity information collection system.
