Medium Voltage Distribution Line Carrier Communication Technology Research

The author have taken pat in studyng and designing the prOject of WFPLC3510Iniddle-voltage power line carrier commnication system. A few kinds of signalseparate measures,double cAner frequency automatc switch function and relayfunction are taken into account on the design of WFPLC-Ml Iniddle-voltagedistribution line carrier Modem .Coupling equipment is designed with the filter andcaPacitance fitted togetheL In this paPef, it is also advanced an scheme about cAnersignal spanning the distribution line break. The equipment system has been finishedand put into use, which has better result.The feasibly and necessity of the studying of this problem are posed. The creativework to this problem and the work to article are described simplyThe author introduces the various ways of communication, compares the powerline cdrier communication and others, the question of the system's designing is putforward, the WFPLC35l0 Anddle-voltage power line carrier communication systemhow to work and how to transInit.The technology of the data and cAner communication are generally described.The conception and formula in designing are introduced.Author introduces how to design the hardware and the software. ST7536 isselected by comparing.Author introduces the principle, the technical character and the technical data ofthe device. It is also advanced a scheme about catrier signal spanning the distributionline break.Author Provides the experiment report of the WFPLC-M1 middle-voltage powerline cAner Modem.
