| Abstract: |
| Aiming at the problems of network time synchronization, transmission time delay and large jitter existing in the communication system of intelligent substation, the multiplexing mode of communication network in intelligent substation is studied and the WDM(Wavelength Division Multiplexing) network architecture mode is proposed. The structure of WDM-PON(Wavelength Division Multiplexing-Passive Optical Network) in new generation of smart substation is based on passive optical network and virtual point-to-point bi-directional transmission links and adopts the business isolation technology, which ensures the stability and reliability of the entire network. The performance indexes of WDM-PON are obtained through simulation and analyzed. The analytical results prove that WDM communication network can satisfy the requirements of substation service on communication network and can be applied to the substation communication network. |
