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.

Dynamic Bandwidth

The advantages of Ethernet passive optical network (EPON) are setting it to be a natural ubiquitous solution for the access network. In the upstream direction of EPON, the directional property of the splitter requires that the traffic flow be mitigated to avoid collision. A dynamic bandwidth allocation (DBA) scheme is desirable in optimizing the bandwidth usage further. In this paper, a global priority DBA mechanism is discussed. The mechanism aims to reduce the overall delay while enhancing the throughput and fairness. This study was conducted using MATLAB where it was compared to two other algorithms in the literature. The results show that the delay is reduced up to 59% and the throughput and fairness index are improved up to 10% and 6%, respectively.
