“…General Structure of SCN As shown in Fig. 1, a typical SCN is constituted of two parts: a process bus network and a station bus network [5], [6]. A process bus network typically carries Sampled Value (SV) (defined in IEC 61850-9-2), Generic Object-Oriented Substation Events (GOOSE) (defined in IEC 61850-8-1) and often Manufacturing Message Specication (MMS) (defined in IEC 61850-8-1) messages [7].…”

“…Table VII shows the sensitivity values for the maximum message delay of G1, when going through Port6 of the Center Switch. L [0,6] max is the packet length of the longest messages tagged with priority from 0 to 6 that goes through Port6. C is the transmission rate of Port6.…”

“…From the results listed in Table VII, it can be concluded that increasing C can reduce the maximum message delay of G1, and reducing ∑ L 7 has a more significant effect on the reduction of the maximum message delay, which is affected by the segmentation of the network, networking scheme and so on. The maximum message delay can also be reduced by shortening L [0,6] max and L G1 . Based on the sensitivity values, the network performance can be optimized by improving the SCN design and adjusting the corresponding parameters, which is the key function of the proposed method.…”

A custom designed and well monitored substation communication network (SCN) can maintain the fast and reliable information transmission and lead to improved operation and management of a substation automation system (SAS). In order to achieve this goal, a traffic flow model, including a port connection model, a traffic flow source model and a traffic flow service model of a SCN is developed in this paper. Based on the traffic flow model, a traffic flow calculation algorithm is designed to obtain the distribution of traffic load and maximum message delay. In order to verify the accuracy of the proposed method, the SCN of a simplified substation is established in the laboratory. And the distribution of traffic load and maximum message delay calculated using the proposed method is compared to that measured by a network analyzer. Further more, possible applications, such as network device selection, network performance analysis and sensitivity analysis, of the proposed method are demonstrated based on a typical 220 kV substation.Index Terms-substation automation system (SAS), traffic flow analytical model, IEC 61850, traffic load distribution, maximum message delay distribution.

“…Signals measured by instrument transformers are digitized and converted to sampled value (SV) Ethernet packets in the MUs, and transferred to the IEDs. Trip, blocking and status signals are transferred through the process bus network using GOOSE [3]. SV and GOOSE are the main information units in the process bus network, and their most rigorous total transmission time shall be below 3 ms, which was clearly and definitely provided in IEC 61850-5.…”

Communication system plays a crucial role in the smart grid, which requires distinct qualities and services closely related to application requirements. A process bus network in the smart substation is a very important component of the smart grid communication system. With the aim to evaluate the performance of the process bus network, the network model and information flow model of the process bus network are constructed and an algorism to calculate the information flow of the network is proposed. Finally, in order to illustrate the calculation procedure, a process bus network of a real substation is taken as a case to study. The same process bus network of the case is also established based on the OPNET platform to make a comparison between the simulation results and the results obtained using the proposed method. The comparison results show the validity and accuracy of the proposed model and algorithm.Index Terms-Smart substation, process bus network, information flow model, information flow calculation.

“…There is also an opportunity to introduce smart technologies into transmission networks to improve observability and control of the high voltage power system, and to achieve greater interoperability between substation control equipment. Sampled value (SV) process buses are a means of achieving this [2], and the benefits of a digital process bus have been well documented in the literature [3]- [5]. Full scale process bus based substations have been commissioned in China, and more are under construction [6].…”

Ethernet is a key component of the standards used for digital process buses in transmission substations, namely IEC 61850 and IEEE Std 1588-2008 (PTPv2). These standards use multicast Ethernet frames that can be processed by more than one device. This presents some significant engineering challenges when implementing a sampled value process bus due to the large amount of network traffic.A system of network traffic segregation using a combination of Virtual LAN (VLAN) and multicast address filtering using managed Ethernet switches is presented. This includes VLAN prioritisation of traffic classes such as the IEC 61850 protocols GOOSE, MMS and sampled values (SV), and other protocols like PTPv2. Multicast address filtering is used to limit SV/GOOSE traffic to defined subsets of subscribers.A method to map substation plant reference designations to multicast address ranges is proposed that enables engineers to determine the type of traffic and location of the source by inspecting the destination address. This method and the proposed filtering strategy simplifies future changes to the prioritisation of network traffic, and is applicable to both process bus and station bus applications.
