Page 40: Voltage Protection 27, 59
Functions 2.2 Voltage Protection 27, 59 Voltage Protection 27, 59 Voltage protection has the task to protect electrical equipment against undervoltage and overvoltage. Both op- erational states are abnormal as overvoltage may cause for example insulation problems or undervoltage may cause stability problems.

Functions 2.2 Voltage Protection 27, 59 2.2.2 Overvoltage Protection 59 Function The overvoltage protection includes three elements (59-1 PICKUP, 59-2 PICKUP, 59 Vp>). In case of a high overvoltage, the switchoff is performed with a short-time delay, whereas in case of lower overvoltages, the switchoff is performed with a longer time delay.

Overload causes the network frequency to drop, which is detected by the under- frequency protection and leads to separation of system components.

Page 62 Functions 2.4 Load Restoration Figure 2-11 Example for Load Restoration with 3 elements In the above example the frequency initially drops below the pickup threshold of the underfrequency element 81-1. The element 81-1 trips. Because of the configured settings (see Table 2-3) load restoration element LR1 is started with the tripping of 81-1.
Page 63 Functions 2.4 Load Restoration During the pickup time of LR2 the network frequency drops briefly below the pickup threshold, but not below the dropout threshold of LR2. This stops the pickup of load restoration element LR2, but does not reset this procedure in the dropout delay time.

Functions 2.5 Monitoring Functions 2.5.2 Trip Circuit Supervision 74TC Devices 7RW80 are equipped with an integrated trip circuit supervision. Depending on the number of available binary inputs (not connected to a common potential), supervision with one or two binary inputs can be selected. If the allocation of the required binary inputs does not match the selected supervision type, then a message to this effect is generated („74TC ProgFail“).

Address 6101 Synchronizing allows you to switch the entire SYNC function group ON or OFF. If switched off, the synchrocheck does not verify the synchronization conditions and release is not granted. Parameter 6102 SyncCB is used to select the switchgear component to which the synchronization settings are applied.

Glossary Battery The buffer battery ensures that specified data areas, flags, timers and counters are retained retentively. 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.
Page 248 Glossary Combination matrix DIGSI V4.6 and higher allows up to 32 compatible SIPROTEC 4 devices to communicate with each other in an inter-relay communication network (IRC). The combination matrix defines which devices exchange which in- formation. Communication branch A communications branch corresponds to the configuration of 1 to n users which communicate by means of a common bus.
Page 249 Glossary Double command Double commands are process outputs which indicate 4 process states at 2 outputs: 2 defined (for example ON/OFF) and 2 undefined states (for example intermediate positions) Double-point indication Double-point indications are items of process information which indicate 4 process states at 2 inputs: 2 defined (for example ON/OFF) and 2 undefined states (for example intermediate positions).

Page 251 Glossary Grounding Grounding means that a conductive part is to connect via a grounding system to → ground. Grounding Grounding is the total of all means and measured used for grounding. Hierarchy level Within a structure with higher-level and lower-level objects a hierarchy level is a container of equivalent objects. HV field description The HV project description file contains details of fields which exist in a ModPara project.
Page 252 Glossary Initialization string An initialization string comprises a range of modem-specific commands. These are transmitted to the modem within the framework of modem initialization. The commands can, for example, force specific settings for the modem. Inter relay communication → IRC combination IRC combination Inter Relay Communication, IRC, is used for directly exchanging process information between SIPROTEC 4 devices.
Page 253 Glossary Master Masters may send data to other users and request data from other users. DIGSI operates as a master. Metered value Metered values are a processing function with which the total number of discrete similar events (counting pulses) is determined for a period, usually as an integrated value. In power supply companies the electrical work is usually recorded as a metered value (energy purchase/supply, energy transportation).
Page 254 Glossary Object properties Each object has properties. These might be general properties that are common to several objects. An object can also have specific properties. Off-line In offline mode a link with the SIPROTEC 4 device is not necessary. You work with data which are stored in files. OI_F Output indication fleeting →...
Page 255 Glossary Protection devices All devices with a protective function and no control display. Reorganizing Frequent addition and deletion of objects creates memory areas that can no longer be used. By cleaning up projects, you can release these memory areas. However, a clean up also reassigns the VD addresses. As a consequence, all SIPROTEC 4 devices need to be reinitialized.
Page 256 Glossary SICAM WinCC The SICAM WinCC operator control and monitoring system displays the condition of your network graphically, visualizes alarms and indications, archives the network data, allows to intervene manually in the process and manages the system rights of the individual employee. Single command Single commands are process outputs which indicate 2 process states (for example, ON/OFF) at one output.
