Tunneling Horizontal IEC 61850 Traffic through Audio Video Bridging Streams for Flexible Microgrid Control and Protection

In this paper, it is argued that some low-level aspects of the usual IEC 61850 mapping to Ethernet are not well suited to microgrids due to their dynamic nature and geographical distribution as compared to substations. It is proposed that the integration of IEEE time-sensitive networking (TSN) concepts (which are currently implemented as audio video bridging (AVB) technologies) within an IEC 61850 / Manufacturing Message Specification framework provides a flexible and reconfigurable platform capable of overcoming such issues. A prototype test platform and bump-in-the-wire device for tunneling horizontal traffic through AVB are described. Experimental results are presented for sending IEC 61850 GOOSE (generic object oriented substation events) and SV (sampled values) messages through AVB tunnels. The obtained results verify that IEC 61850 event and sampled data may be reliably transported within the proposed framework with very low latency, even over a congested network. It is argued that since AVB streams can be flexibly configured from one or more central locations, and bandwidth reserved for their data ensuring predictability of delivery, this gives a solution which seems significantly more reliable than a pure MMS-based solution.

The Research, Implementation and Telegram Analysis of IEC61850 Services Mapping to MMS Read

IEC61850 uses the abstract communication service interface (ACSI) and specific communication service mapping (SCSM) definition method. Most of data structure and communication service are mapping to Manufacturing Message Specification (MMS), but MMS has high abstraction, many 61850 ACSI services are mapping to one mms service [6]. At the same time there are many fuzzy definitions even mapping deviation phenomena, different vendors may have inconsistent understanding to the standard, this is harmful to the interoperability. This paper provide analysis and comparison to the 61850 ACSI services mapping to the MMS read, including GetDataValues, GetDataSetValues, GetBRCBValues and so on, and based on these, firstly gives implementation using the mms-ease lite of SISCO Company and detailed explanations of actual telegram. Our research is helpful to eliminate understanding difference and achieve interoperability. System test uses multiple popular software of different company to simulate as server, and the widely used network protocol analyzer software Omicron IEDScout is used to capture packets, the result verifies our implementation satisfy the functionality and interoperability.

Role-based access control for substation automation systems using XACML

There has been an increasing need for accessing data of internal equipment and devices of a substation system from external systems as power grids evolve. This has also introduced growing concerns on data security. In response to the concerns, IEC 62351 has proposed role-based access control (RBAC) for substation automation. In this work, we present a novel approach for implementing RBAC based on IEC 62351 for substation automation using eXtensible Access Control Markup Language (XACML). We integrate the approach with IEC 61850 by extending Abstract Communication Service Interface (ACSI), Manufacturing Message Specification (MMS), and System Configuration Language (SCL). A major advantage of the approach is that it fully conforms to both IEC 61850 and IEC 62351 and highly compatible with SCL as both XACML and SCL are XML-based. We implement the approach using OpenIEC61850 which is an open source library for ACSI services and demonstrate the implementation.

Novel Approach for Detecting Network Anomalies for Substation Automation based on IEC 61850

An SA (Substation Automation) system based on IEC 61850 is an intelligent substation; it has been receiving considerable attention as a core component of a smart grid. The explosive increase of threats to cyber security has been expanded to critical national infrastructures including the power grid. Substation Automation has also become a main target of cyber-attacks. Currently, various countermeasures such as firewalls, IDS (Intrusion Detection System)s, and anti-virus solutions have been developed, but to date, these have not sufficiently reflected the inherent features of Substation Automation based on IEC 61850. This study suggests a method of anomaly detection for MMS (Manufacturing Message Specification) and GOOSE (Generic Object Oriented Substation Events) packets, the main communication protocols of IEC 61850 Substation Automation. 3-Phase preprocessing, EM (Expect Maximization), and one-class SVM (Support Vector Machine) techniques are applied. The effectiveness of the suggested method is evaluated through experiments.

Secure Message Transmission Method of MMS Telecontrol Communication Based on AES-CCM

With the application of Ethernet communication architecture in electric power telecontrol communication, new requirements of information security have been put forward based on Manufacturing Message Specification (MMS). IEC62351 standard makes two clear security requirements for MMS, which is confidentiality and integrity. Taking into consideration the increasing costs if one algorithm corresponds to one security requirement, this paper designs a MMS-based security message format, applying AES-CCM encryption algorithm to satisfy various safety demands and analyzes algorithms time costs as well as benefits with an example of authenticated encryption mode. Analysis shows that security and interoperability of telecontrol communication can be improved to a large extent using different modes of AES-CCM algorithm for security message transmission under distinct security requirements.

Service-oriented communication architecture for automated manufacturing system integration

The heterogeneity of industrial environments is one of the most important challenges in the context of automated manufacturing system integration. To realize common industrial messaging services, this study employs service-oriented philosophy to realize manufacturing message specification (MMS) services and proposes a new concept of MMS Web Services, which rediscovers the semantics of MMS. Then, this study presents manufacturing communication model based on MMS and Web Services and provides service-oriented communication architecture (SOCA). On the basis of describing MMS, a protocol data unit (PDU) design based on Web Services and VMD server message transmission interfaces, manufacturing communication subsystem using unified modeling language model is discussed in detail. In particular, to verify the validity of the proposed design method, a prototype system has been achieved. The resulting prototype proves the effectiveness of MMS standard, Web Services middleware and service-oriented concepts in the design of manufacturing communication architecture. The combination of MMS and Web Services can bring truly platform-independent and language-independent communication capability for automated manufacturing system and improve its flexibility, reconfigurability and interoperability. Furthermore, the proposed communication architecture can be seamlessly integrated into manufacturing control systems or management systems in plug-and-play fashion.

DCOM and MMS–based control software architecture for automated manufacturing system

In this paper, we introduce the manufacturing message specification (MMS) and compare two distributed object approaches–distributed component object model (DCOM) and common object request broker architecture (CORBA), suggest characteristics that DCOM is more suitable for automated manufacturing system (AMS) control software integration. In order to make a control system provided with interoperability and reconfigurability etc., a hybrid control system is built for AMS, then a control software architecture is presented for AMS based on distributed object DCOM middleware and MMS standard. The object-oriented DCOM communication protocol is used to implement the MMS in a distributed object mode. DCOM and MMS combination brings the operating system independent communication capabilities to manufacturing devices such as CNC machine tools and industrial robots in AMS. Control software implementation of MMS concepts in the DCOM environment is particularly discussed. Finally, to verify the control software architecture for AMS, prototype development has been implemented in VC++ 6.0 developer environments.

Integration of manufacturing services into virtual environments over the internet

Virtual reality (VR) is a rapidly developing technology that has a wide spectrum of industrial and commercial applications. Networked (distributed or shared) virtual environments (VE) are of growing interest to modern manufacturing industry; a dominating use of networked virtual manufacturing environments (VMEs) is on-line visualisation and collaborative control of 3D information. This has to be supported by real-time data transfer. To meet a broad range of common requirements for Internet-based VE communications, particularly for virtual manufacturing and collaborative design and control, this paper presents a networked virtual environment system that is designed to support networked virtual design and manufacturing. The system is implemented with manufacturing message specification (MMS) standards so as to integrate a range of manufacturing services into networked VEs over the Internet.

QoS and network resources management for communication in distributed manufacturing processes

In this paper, we present a multimedia communication model based on the virtual manufacturing device (VMD) concept that has been defined in the international manufacturing message specification (MMS). This model called the virtual communication support (VCS), makes it possible to cohabit different communication techniques, such as ATM and ethernet, provides a multi-profile solution to introduce real-time multimedia applications and manages network resources. Its specification and design used to perform workstation capabilities to avoid network bottleneck. For these purposes, it defines a service set between the application layer and the other communication layers to manage network resources reservation negotiate the quality of service (QoS) and ensure real-time service execution. The design of this communication model is based on the idea of the specification and description language (SDL) use. It is a formal description technique that enables model validation, extension and reusability. The dynamic behavior of this model is being checked with the message sequence chart (MSC). The implementation and the experimentation of this VCS model are being achieved using the JAVA language. It is being done on the fast-ethernet local area network equipped with multimedia and manufacturing devices.

A Generic MMS–Based Holon Structure

Abstract This paper is about decentralised intelligent manufacturing systems, with the specific aim of proposing a generic Manufacturing Message Specification (MMS) based holon which can be used to control different manufacturing devices with simple reconfigurations. MMS is avendor–independent communication protocol for manufacturing devices and is used as a tool to control heterogeneous manufacturing devices. The generic MMS–based holon structure was implemented in the Microsoft Windows environment and incorporates stand–alone devices such as a robot or a CNC Lathe into a networked environment. The outcome of the research shows that the MMS protocol is suitable for generating modular mini–structures to implement holonic, biologically oriented and fractal manufacturing systems.

Industrial systems communications: Design and integration

The configuration of the communication between entities of an automated production system could be derived from the design of its information system. Thus, our objective is the design and integration of the industrial communications of distributed automated systems. Based on the information system study, without having recourse to new modelling tools, we want to generate the configuration of the communication system while guaranteeing consistency between these two systems. Hence we offer to the designer of the production system the means that are necessary for the realization of his or her system. In order to reach our objective we are using objectoriented design methods (i.e. OMT: Object Modelling Technique) for the information system study and the industrial protocol MMS (Manufacturing Message Specification) for the communication system. In order to allow the transition step from conceptual stage of the information system to the MMS environment, we have defined some translation rules. These rules are studied from the point of view of the implementation constraints. In order to validate our approach and its feasibility we have presented a remotecontrol application of an industrial robot with feedback video for which the MMS objects and services are generated.
