2. Telecontrol: The second stage involves switchgear telecontrol in addition to monitoring, thus minimizing downtime. Thanks to this application, fault isolation and power supply restoration of de-energized network sections are no longer difficult tasks for power supply utilities.
3. Load flow control: In the third stage, the effects of decentralized power feed-ins are managed via automation. Network losses can be significantly reduced this way.

The 6MD63 bay control unit is a flexible, easy-to-use control unit. It is optimally tailored for medium-voltage applications but can also be used in high-voltage substations. The 6MD63 bay control unit has the same design (look and feel) as the other protection and combined units of the SIPROTEC 4 relay series. Configuration is also performed in a standardized way with the easy-to-use DIGSI 4 configuration tool. For operation, a large graphic display with a keyboard is available. The important operating actions are performed in a simple and intuitive way, e.g. alarm list display or switchgear control. The operator panel can be mounted separately from the relay, if required. Thus, flexibility with regard to the mounting position of the unit is ensured. Integrated key-operated switches control the switching authority and authorization for switching without interlocking.

Application

• Optimized for connection to three-position disconnectors
• Switchgear interlocking interface
• Suitable for redundant master station
• Automation can be configured easily by graphic means with CFC

The efficient operation of modern distribution grids requires quick fault detection, message packing and provision for further processing. The SICAM Fault Passage Indicator (FPI) is one component for that. The FPI is used for phase fault detection and indication and for detection of earth faults in radial or open ring medium-voltage cable networks. 4 external current sensors detect phase faults (L1, L2, L3) and earth faults (E). The current sensors detect phase fault and earth fault currents based on the set current threshold detection, and communicate them to SICAM FPI via an optical signal. The rotary switch on each sensor is used to set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1), 200 A to 800 A (Type 2) and for earth sensors from 10 A to 100 A (Type 1), 40 A to 300 A (Type 2). If the current exceeds the set threshold level, the current sensor will send an input to SICAM FPI via plastic fiber-optic cable. In this condition, the corresponding LEDs are flashing and the binary contacts are picking up. In normal operating conditions, there is no LED indication.

·         Siemens SICAM DISTO Software for detection and storage of fault records

An important function of digital protection is to store disturbance records for more accurate analysis of critical events in the grid. As the memory for such records is limited in the relay it has shown convenient to extract them by use of standardized communication and store them on a hard disk on station level for further use. Serial communication of digital protective devices to Substation Control Systems has been standardized and published as IEC standard protocol 60870-5-103. Recently the new standard for power utility communication IEC 61850 has added much more flexibility and performance to data exchange with different IEDs.

·         Features: SICAM DISTO (disturbance data storage)

is a software package, which recognizes the occurrence of new disturbance records in the connected protection relay fetches them by means of substation communication and stores them in preconfigured directories on the hard disk of a PC. For easy analysis with different tools DISTO uses the standardized OMTRADE  format for all disturbance files according to IEC 60255-24). Whereas DISTO has to translate incoming disturbance records from IEC 60870-5-103 into COMTRADE, the transmitted files in IEC 61850 are already in the right format. 

·         Some protection relays send COMTRADE files packed in zip files over IEC 61850. SICAM DISTO recognizes such files and unpacks them into the right directories. Using IEC 61850, SICAM DISTO expects the transmission of fault records per MMS. The option with FTP is not supported. If using IEC 60870-5-103, DISTO prepares in addition an event list with all protection-relevant information, such as fault number, fault distance etc., both with absolute and relative real time (within a storing disturbance).

·         The stored files contain the time dependent behaviour of currents and voltages before, during and after a disturbance in the grid, plus additional events (e.g. trips). These data can be displayed as graphs on screen using SIGRA or other software tools with analyzing functions. 

·         For accessing the communication to the relays, DISTO makes use of SICAM 230 or 250 SCALA and their integrated communication drivers. Remote access to the stored files is available by use of standard tools of the operating system.

Siemens SIPROTEC 6MD61 Bay Controller

The SIPROTEC 6MD61 enables in a simple, easy way to enhance the number of binary inputs and outputs in the switchgear. It can be used directly in the bay together with other SIPROTEC4 units and also together with SICAM PAS to serve as a central process connection. The IO-Box is based on the SIPROTEC 6MD63 and 6MD66 series, so it can be easily integrated in systems with other SIPROTEC 4 units. The IO-Box supports a wide range of demand for additional binary inputs (BI) and binary outputs (BO), starting from 20 BI+10 BO and going up to 80 BI+53 BO. All important standard communication protocols are supported. With IEC 61850-GOOSE communication, a direct information interchange with other SIPROTEC units is possible. For simplification and cost reduction, the IO-Box is available only without automation (CFC), without keypad and without display.

Online engineering of SICAM A8000. SICAM WEB is the easiest way of configuring and testing SICAM A8000 devices. The configuration and diagnosis of the remote and automation devices of the SICAM A8000 series can be done with a tablet or PC and a standard browser.

Simply enter the IP address of the SICAM A8000 device into the browsers address bar and then, in the SICAM WEB login dialog, enter your login data.

Communication with the SICAM A8000 device will then be bidirectional via an Ethernet connection.

Time-consuming download and installation of software is not required anymore!

Authorizations and the available engineering and diagnosis options depend on whether the user is logged in as an administrator or as a guest.

Based on this, device and diagnostics information can be read out or event and alarm messages can be checked.

Administrators additionally have the right to change configuration data or to start test routines.

User interface

SICAM WEB can be operated with a mouse or via touch screen.

Every function area has its own tile and also its own menu entry.

Communication

SICAM WEB is optimized for low bandwidths regarding data transfer, no matter how the SICAM A8000 device is connected.

The following connection options are available:

• Direct Ethernet connection
• Wi-Fi with a router connected to the device

SICAM WEB has only lean bandwidth requirements.

Configuration

SICAM WEB can be used to read information from SICAM A8000 devices as well as for the complete configuration. Key parts of configuration are signals, for example messages, commands, measured values or counter values.

The signals are configured in a simple and clear workflow:

• Each required signal is defined with its name and an IEC 60870-5-101/104 address.
• Signals are assigned to different targets, for example I/O modules, protocols or the master module.
• An I/O module is selected as target for signals to the process and from the process.
• If data transfer with another station is not done via IEC 60870-5-101 or -104, the telegram address must be converted. In this case, the signals to be transferred must be assigned to the used protocol.
• Internal system functions, like writing data into the alarm or event list, must be directly assigned to the master module as the target for the relevant signals.
• Multiple assignments of the same signal to several targets are possible. In some cases, the configuration of assignment-specific parameters may be required.
• As a last step, all settings are stored in the device.

The process and visualization system SICAM SCC is a central element of energy automation solutions. The system is independent of the substation technology installed. SICAM SCC is compatible with the SICAM PAS Power Automation System, the products of the SICAM RTUs line. And in case you are not using a substation controller in your station: SICAM SCC communicates directly with bay units and protection devices that support the IEC 61850 communication standard. As a result it can be used as an overall HMI system for devices.
