Abstract:For power companies, numerous equipment and devices play important roles in their daily operation. Distribution network serves a quite crucial part, which guarantees its better performance and can better the power transmission. That being the case, automation technology emerges in the distribution network application and hence the distribution network automation (DNA) is formed. Aiming at enhancing yet even more the performance of the distribution network automation, this paper studied the application of passive optical network technology in the distribution network automation technology, hoping to lay a sound foundation for the development of China’s power industry.

This paper presents the implementation of CMTS (Cable Modem Termination System) with PON (Passive Optical Network) technology to transfer IP data in HFC (Hybrid Fiber-Coax) network. By describing the theoretical basis and main function of each module, we introduce work principle of this device: converted the format of data transmitting in HFC network so that it can transfer in IP network, then achieved the aggregation of IP data to transport layer device by PON technology. The results show that the SNR is high and the bandwidth achieves expected value, so this design scheme is feasible.

Smart Substation

Ethernet passive optical network is a new optical access network technology characterized by low cost, high bandwidth, little electromagnetic interference, strong scalability, and powerful compatibility. The auxiliary control system of smart substation includes video surveillance system that carries large data volume but raises low real-time requirement. Constructing the auxiliary control system in the station with Ethernet passive optical network can effectively solve the problem of export bandwidth allocation without using a switch, thus greatly saving the investment in network construction and the costs for life-cycle maintenance. It is therefore regarded as an efficient new networking scheme for the auxiliary control system of smart substation. This paper analyzes the feasibility of applying Ethernet passive optical network technology in the auxiliary control system of smart substation, proposes a program to construct a 220kV smart substation using Ethernet passive optical network, and conducts an economic comparison, in an attempt to provide a new solution for the data transmission of the auxiliary control system of smart substation.

This article presents a design of a database model used to gather and analyze data frames transmitted over gigabit passive optical network (GPON) in the downstream direction. An issue with this kind of system is the difficulty in analyzing a transmission on the optical part which is caused by the difference among devices using Ethernet frames technology and passive optical network technology with usage gigabit encapsulation method. In this article, a principle of the downstream direction is described. Next, the design of the database model for the analysis of transmitted data is discussed. Based on the design and implementation of the database, a script capable of processing data gathered by a programmable network card is proposed. The script for physical layer operation, admission, and maintenance (PLOAM) messages analysis is written in the Python programming language.

P2p Service

AbstractFor the effective bearer of P2P-type services, a P2P service bearer reorientation method for passive optical network for long-distance wide access based on P2P protocol message and wire-speed message identification is proposed. However, the reorientation method still has the possibility of relocation failure, so it is modified – that is, an improved P2P service bearer reorientation method based on optical line terminal (OLT) and optical network unit (ONU) cooperation. And the tool NS2 is used for network simulation analysis. Through simulation analysis, it is verified that the modified reorientation method improves the data traffic burden at the core network and at the OLT.
