Abstract-High-availability Seamless Redundancy (HSR) is an emerging standard that is suitable for mission-critical communication of IEC 61850 based Substation Automation System in smart grid, where the dependability is very important. This redundancy protocol provides zero recovery time by offering duplicated frames for separate physical paths, but it generates and circulates unnecessary traffic inside the network that will degrade the performance of the network and may cause the congestion, delay, or frame loss. To improve the HSR network performance, the main drawback of generating extra traffic should be considered and eliminated. This paper demonstrates comprehensive performance analysis of IEC 61850 based substation automation networks and applies the quick removing (QR) algorithm to improve the performance of the HSR network to overcome the major drawback. The performance analysis includes the HSR modules, i.e., Doubly Attached Node for HSR (DANH), Redundancy Box (RedBox), and Quadruple Box (QuadBox), and IEC 61850 services, i.e., Generic Object Oriented Substation Events (GOOSE), Sampled Measurement Values (SMV), and report service. Performance analysis was conducted to verify the timing constraints described in IEC 61850 as a reference for designing proper HSR network topology. The numerical results show that the frame loss, restricted in mission-critical network, occurs due to large amount of traffic volume, which is the main drawback of HSR. The QR algorithm improves the traffic performance of HSR by reducing the unnecessary traffic along with the decrease of packet loss significantly.

“…Substation communications network usually use TCP/IP protocol stack as a network layer and transport layer protocol, in order to ensure openness and interoperability of systems [9]. An optimized network engineering tool (OPNET) or Riverbed modeler is used to simulate various SAS networks under diverse scenarios, allowing user to set the raw sample rate, fault time, number of faults, background traffic and other configuration parameters [10].…”

Abstract-Substation plays an important role in power system communications for safe and reliable operation of entire power networks. Substation communication networks are connected with various substation intelligent electronic devices (IEDs), which is substation systems lifeblood and the system availability is decided by its real-time performance. International Electrotechnical Commission (IEC) has been developed the standards based on object-oriented technologies for substation automation. IEC 61850 protocol has been applied widely in substation communication applications. It presents new challenges to realtime performance simulation and testing of protective relays. In this paper, an optimized network engineering tool (OPNET) or Riverbed modeler simulation tool/ software has been used for the modeling of IED in substation level network. Based on the simulation results, different types of data stream have been discussed, such as, periodic data stream, random data stream and burst data steam. The typical studies using these models, to construct substation automation system (SAS) network on the OPNET modeler or Riverbed modeler was made to reveal the impact of each affecting parameter or factor to the real-time performance of substation communications system, which is also incorporated in this report.Index Terms-IEC 61850, OPNET or Riverbed Modeler, Power system simulation, Real-time, Substation automation system (SAS), Transmission delay. I. INTRODUCTIONubstation intelligent electronic devices (IEDs) are transmitted data through the data communications network. Once the data packets transfer has been delayed and has not been reached to the target devices within the predetermined period of time, which may lead to extremely serious consequences, and endanger the substation and even the entire grid [1][2][3][4][5][6][7][8]. The key objectives for designing any substation automation architecture are interoperability between the IEDs, satisfaction of communication performance, and extensibility of the architecture. The IEC 61850 is a global communication standard for substation automation system (SAS) defines the communication between the IEDs and not only solves the interoperation problem but also specifies other system requirements like message performance, information security in the SAS networks [6]. Substation communication network transmission packets have strict delay requirements, real-time study for the underlying communication network, in particular, the media access control (MAC) layer protocol, while ignoring the real-time upper-layer protocols [2]. The transmission protocol, network load and networking mode are the main factors affecting the real-time performance of the SAS network [3][4]. Among the transmission delay constitution factors, message packaging and parsing take up most of the time, which relates to the transmission model and protocol [5].According to IEC 61850-5 standards, the messages transmission time requirements for the SAS network must be ensured under any operating conditions and cont...

“…The object model and its services are mapped to the MMS application layer (i.e., layer 7). Only time-critical services, such as Sampled Values and Generic Object Oriented Substation Event (GOOSE) messages, are mapped directly to the Ethernet link layer (i.e., layer 2) in order to ensure openness and interoperability of systems (Kanabar and Sidhu, 2011). Additional mappings to other communication stacks are possible.…”

This paper presents the application of IEC 61850 protocol in electrical power engineering industry for data communication systems between substations. This IEC 61850 protocol presents new challenges for real-time communication performance between Intelligent Electronic Devices (IEDs) within substation because of the Generic Object Oriented Substation Event (GOOSE) messages. The analyses of substation Ethernet and WLAN (wireless LAN) communication delay, its impact factors, various methods and different network topologies which can improve the real-time performance are discussed. For basic analysis of data flow within a substation, the Optimized Network Engineering Tool (OPNET) software is used. The process-to-bay level network simulation model is performed by using the OPNET software. The Ethernet delay and WLAN peer-to-peer performance of the process-to-bay level network simulation results are analyzed which is based on AP (access point), switched, shared Ethernet network or peer-to-peer network.
