For this reason and thanks to the positive experience gained in initial pilot projects with IEC 61850 in the field of power distribution. It is based on an object-oriented data structure with a strictly hierarchical separation of the process interfaces (data acquisition). the decision was made at an early stage to implement the direct integration of the auxiliary power supply in accordance with IEC 61850. With its object-oriented data structure and the Ethernet network as a communication platform. © Siemens AG 2009. municipal utilities and infrastructure services to industrial locations. Today IEC 61850 is the globally accepted communication standard for switchgear systems and can already be regarded as the state of the art. 4 . This is a complex procedure involving between 1000 and 5000 signals depending on the size of the unit and the energy source. Only a small selection of information would usually be transferred via this interface. IEC 61850 is based on fast.1 Instrumentation. Up to now plants have generally acquired or output this information via bit-parallel or analog input/output modules. The number of devices available with IEC 61850 is increasing steadily and devices for all the tasks of the auxiliary power supply are already available today. These signals are output locally via contacts and need to be engineered. Controls & Electrical Integration of auxiliary power supply Creating a link to and integrating information from the auxiliary power supply is nothing new. it has successfully established itself in all areas of power distribution. 20. Implemented systems range from traction networks (400 kV) to distribution networks (110. With bit-parallel links. This was especially inconvenient in the event of fault evaluations. information has had to be supplied to the I&C system via marshaling racks. in unit protection and in other components of the auxiliary power supply.Siemens Energy Sector 1. through power supply companies. primarily Ethernet-based communication. If greater convenience was to be achieved for the auxiliary power supply. cabled and commissioned. Since IEC 61850 was accepted as the worldwide standard for power distribution systems in 2004. Digital devices with communication interfaces are already implemented in switchgear systems. such as system interlocking or intertripping. The devices are connected via an Ethernet network and to the automation bus of the I&C system. a separate switchgear control system had to be set up as an alternative so as to permit the exchange of information between the two control systems over a dedicated link.

When the control system logs onto the bay control device as a client on startup. the link to the automation. which would again be susceptible to errors. the import interface detects the changes and reduces or adds to the data inventory accordingly. this means that the engineering tool of the bay control device selects all the information visible to the I&C which can be retrieved using this tool. the display of data points. Controls & Electrical IEC 61850 distinguishes between two reporting procedures: „ Static reporting „ Dynamic reporting If devices communicate using the static reporting procedure. This procedure is mainly necessary if the connected IEC 61850 components only support static reporting.anything up to 1200 data points are possible with a SIPROTEC device.e. If the connected IEC 61850 components support dynamic reporting. Since no changes are necessary in the bay control devices. a delta import of the SCD file or signal list is possible. and if additional information is required in the I&C. This selection is visible in the SCD file and is therefore detected by the I&C system. however. this only needs to be added to the I&C system engineering. Importing the signal list automatically deletes all the data points which are not required from the SCD file. the derivation of alarms. etc. Standardization of the structure and content of the SCD files means that they can also come from different system suppliers.Siemens Energy Sector Instrumentation. © Siemens AG 2009. thereby requesting only the data contained in this logon. This is why the SCD also includes all the available data points . During configuration the I&C selects the 20 to 40 items of information which are required. For this reason the signal list is imported in addition to the SCD file and is used for the determining the message scope during the clarification phase. whereupon the data are made available to the I&C system. the SCD file does not need to be reimported. Further processing of engineering data from the SCD files and the signal list is performed using the standard tools of the I&C system. 16 .

A very convenient solution was realized by Siemens in the SIPROTEC 4 devices. In practice the network will usually be a mixture of a ring structure and a star structure.1 Design of IEC 61850 network IEC 61850 standardizes a 100 Mbit Ethernet network as the communication platform. Network design and examples 5. The detailed design of the network is largely determined by the communication interfaces of the connected components. In the LV network and in the links to other auxiliary power supply components. The links to bay control devices and IEC 61850 components are implemented in a star configuration with RJ45 connecting cables. This means that. the network switches are integrated in fiber-optic ring structures. This reconfiguration of the ring is performed with changeover times << 100 ms. ensures the necessary fault tolerance in the network such that. The ring structure and ring management. Controls & Electrical 5. which reconfigures the ring in the event of faults in the network such that all nodes become accessible if at all possible.Siemens Energy Sector Instrumentation. all the other components in the network continue to be accessible and the failure only has minimal effects on operation of the other equipment. if GOOSE functions are used.

A ring structure was exclusively configured in the MV network and in the link to the unit protection. If the device has two interfaces. Although a star-shaped network design is actually permitted by the standard. it is not to be recommended due to the lack of redundancy. which is also standardized in IEC 61850. All Rights Reserved. The simplest form is an RJ45 interface. This permits the device to be connected to a network switch. These feature two fiber optic interfaces at the rear and the switch functionality was integrated directly in the device. a redundant switch can also be connected. . No switches from other suppliers are currently released for use. they can be connected by two different methods: „ By means of a direct link to the fiber-optic rings or „ By means of RJ45 links to additional network switches Direct integration in the fiber-optic ring must always be given preference due to its superior electromagnetic compatibility (EMC) if bay control devices are installed directly in the LV section of the switchgear system.
