Page 20: Overall Operation
Introduction 1.1 Overall Operation Overall Operation The digital SIPROTEC 7SD80 overcurrent protection is equipped with a powerful microprocessor. It allows all tasks to be processed digitally, from the acquisition of measured quantities to sending commands to circuit breakers. Figure 1-1 shows the basic structure of the 7SD80 device.
Page 21 Introduction 1.1 Overall Operation The analog-to-digital (AD) element consists of an analog-to-digital (A/D) converter and memory components for data transmission to the microcomputer system. Microcomputer System Apart from processing the measured values, the microcomputer system μC also executes the actual protection and control functions.
Page 22 Introduction 1.1 Overall Operation Power Supply The functional units described are supplied by a power supply (PS) with the adequate power in the different voltage levels. Transient voltage dips may occur if the auxiliary voltage supply system becomes short-circuited. Usually, they are bridged by a capacitor storage (see also the Section 4 Technical Data).
Page 23: Application Scope
1.2 Application Scope Application Scope The digital Line Differential Protection SIPROTEC 4 7SD80 is a selective short-circuit protection for overhead lines and cables with single- and multi-ended infeeds in radial, ring or any type of meshed systems of any transmission level. The measured data are compared separately for each phase.
Page 24 Introduction 1.2 Application Scope conditions for switching (e.g. switchgear interlocking) can be defined with the help of integrated user-config- urable logic functions. Messages and Measured Values; Recording of Event and Fault Data The operational indications provide information about conditions in the power system and the device. Meas- urement quantities and values that are calculated can be displayed locally and communicated via the serial interfaces.

Functions 2.2 Phase Comparison Protection and Ground Differential Protection Phase Comparison Protection and Ground Differential Protection The differential protection can be used in solid or resistive grounded, isolated and resonant-grounded systems. It comprises a phase comparison protection and a ground differential protection. The sensitive ground element operates directionally or non-directionally.
Page 49: Phase Comparison Protection
Functions 2.2 Phase Comparison Protection and Ground Differential Protection Phase Comparison Protection 2.2.2 2.2.2.1 Functional Description General The phase comparison protection evaluates the phase currents at both ends of the protected object. The 2 7SD80 devices at the ends of the protected object communicate over their protection interfaces. The phases- pecific comparison and the resulting decision to trip the circuit breaker is made separately for each end.
Page 50 Functions 2.2 Phase Comparison Protection and Ground Differential Protection If the pickup is successful, an internal pickup signal is transmitted to the other device. The element Ιdyn is blocked if the frequency deviates by more than 10 % from the rated frequency. The function is blocked if the communication between the two devices at the ends of the protected object fails for more than two measuring cycles.

Page 403: Glossary
Glossary Bay controllers Bay controllers are devices with control and monitoring functions without protective functions. Bit pattern indication Bit pattern indication is a processing function by means of which items of digital process information applying across several inputs can be detected together in parallel and processed further. The bit pattern length can be specified as 1, 2, 3 or 4 bytes.
Page 404 Glossary Communication branch A communications branch corresponds to the configuration of 1 to n users that communicate by means of a common bus. Communication reference CR The communication reference describes the type and version of a station in communication by PROFIBUS. Component view In addition to a topological view, SIMATIC Manager offers you a component view.
Page 405 Glossary DP_I → Double point indication, intermediate position 00 Drag and drop Copying, moving and linking function, used at graphics user interfaces. Objects are selected with the mouse, held and moved from one data area to another. Earth The conductive earth whose electric potential can be set equal to zero at every point. In the area of earth elec- trodes the earth can have a potential deviating from zero.
Page 406 Glossary ExSI External single point indication via an ETHERNET connection, device-specific → Single point indication ExSI_F External single point indication via an ETHERNET connection, Spontaneous event, device-specific → Fleeting indication, → Single point indication Field devices Generic term for all devices assigned to the field level: Protection devices, combination devices, bay control- lers.
Page 407 Glossary Internal double point indication → Double point indication ID_S Internal double point indication, intermediate position 00 → Double point indication International Electrotechnical Commission, international standardization body IEC61850 International communication standard for communication in substations. The objective of this standard is the interoperability of devices from different manufacturers on the station bus.
Page 408 Glossary LFO-Filter (Low-Frequency-Oscillation) Filter for low frequency oscillations Link address The link address gives the address of a V3/V2 device. List view The right window section of the project window displays the names and icons of objects which represent the contents of a container selected in the tree view.
Page 409 Glossary Measured value with time Measured value, user-defined Navigation pane The left pane of the project window displays the names and symbols of all containers of a project in the form of a folder tree. Object Each element of a project structure is called an object in DIGSI. Object properties Each object has properties.
Page 410 Glossary PROFIBUS PROcess FIeld BUS, the German process and field bus standard, as specified in the standard EN 50170, Volume 2, PROFIBUS. It defines the functional, electrical, and mechanical properties for a bit-serial field bus. PROFIBUS address Within a PROFIBUS network a unique PROFIBUS address has to be assigned to each SIPROTEC 4 device. A total of 254 PROFIBUS addresses are available for each PROFIBUS network.
Page 411 Glossary Single point indication Single indications are items of process information which indicate 2 process states (for example, ON/OFF) at one output. SIPROTEC The registered trademark SIPROTEC is used for devices implemented on system base V4. SIPROTEC 4 device This object type represents a real SIPROTEC 4 device with all the setting values and process data it contains. SIPROTEC 4 Variant This object type represents a variant of an object of type SIPROTEC 4 device.
Page 412 Glossary User address A user address comprises the name of the user, the national code, the area code and the user-specific phone number. Users From DIGSI V4.6 onward , up to 32 compatible SIPROTEC 4 devices can communicate with one another in an Inter Relay Communication combination.
