The PC operating program DIGSI 4 is the user interface to the SIPROTEC devices, regardless of their version. It is designed with a modern, intuitive user interface. With DIGSI 4, SIPROTEC devices are configured and evaluated – it is the tailored program
for industrial and energy distribution systems.
All energy suppliers – whether they provide electricity, natural gas, water, or district heating – face ever greater and more complex demands as they implement new energy mixes. SICAM 230 is a scalable system for a broad range of applications and can be used from an integrated energy system for utility companies to a monitoring system for smart grid applications.
The SICAM 230 architecture is completely consistent – from the on-site controls to the redundant multi-hierarchic control system. New in the control room: SICAM 230 supports multi-touch controls. Use familiar gestures such as “swipe” or “zoom” for optimal control – to move or zoom in on a world view, for example. Adaptable multi-screen concept: SICAM 230 allows different monitor configurations within a single project. Screen layouts and user concepts can be tailored to the individual.
The user interface and display elements of system windows such as lists, trend charts, and log outputs can be parameterized, so users see only those features relevant to the processes they monitor.
Systematic locking mechanisms at the operating system level ensure secure operation, blocking unauthorized access to other system functions. Installing SICAM 230 is comparable to configuring standard software such as the Microsoft Office Suite. OPM II is the ideal tool to create and maintain the basic data model. This object-oriented process data manager is part of the SICAM TOOLBOX II engineering software for the entire SICAM product family.

SICAM Fault Passage Indicator (FPI) is a device that is used for detection and signalling of short circuit and earth-fault on medium voltage cable networks.
4 external current sensors detect the phase faults (R, Y, B) and earth-fault (E).
The current sensor detects phase fault and earth-fault current based on the set current threshold detection and communicate to SICAM FPI via an optical signal.
By using the rotary switch available on the individual sensor, you can set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1 Series), 200 A to 800 A (Type 2 Series) and for earth sensor from 10 A to 100 A (Type 1 Series), 40 A to 300 A (Type 2 Series).
When the current exceeds the set threshold level, the current sensor provides an input via plastic fibre-optic cable to SICAM FPI. In this condition, the corresponding LEDs blink. In normal operating condition, there is no LED indication.
SICAM FPI is used as a fault detection and indication unit. SICAM FPI is used in the feeder and distribution automation of secondary medium-voltage systems that ranges from 10 kV to 36 kV.

Automatic load shedding: Fail-safe power supply for core components
In case of overload, automatic load shedding stabilizes the power supply of large-scale industrial plants through the prioritized disconnection of consumers, thereby ensuring that core processes remain under power in critical situations and expensive downtimes are avoided. This function is especially important when grid stability is put at risk by critical events. In this case, low priority consumers are disconnected in order to restore the balance between energy generation and consumption.
Prepared for every eventuality
To ensure grid stability at all times, the automatic load shedding system analyzes all possible fault patterns in advance and calculates which loads will need to be disconnected. In the event of a fault, the system recognizes which of these scenarios pertains and disconnects the relevant consumers within a tenth of a second.
Power-based load shedding continuously calculates the necessary reactions to critical scenarios that could occur and is therefore prepared for all eventualities at all times. This predictive approach is used for fast load shedding as well as for blocking of large loads.
Fast power-based load shedding
Critical events – like a disconnection from the external power utility grid or the failure of a generator in island mode – require the fastest load shedding possible in order to limit the resulting drop in power frequency and prevent triggering of the underfrequency protection. The system only sheds as much load as necessary for restoring the rated frequency.
Dynamic power-based load shedding
In stable island mode, loads change as needed by the industry process. These variations are balanced by the primary control of the on-site turbines. As the power requirement increases, the spinning reserve decreases, reducing the capability for starting big loads. Dynamic load shedding monitors the spinning reserve for a defined limit value. While it is permissible to exceed the limit for short periods, load is shed if these periods last for longer in order to restore the required reserve. In addition, in island mode large consumers are monitored while in the idle state. If the spinning reserve falls below these starting power level, a signal inhibits the start and so prevents grid overload.
Frequency-based load shedding
This function is available both as an independent main function for ordinary applications and as a reserve function for fast power-based load shedding. It monitors when the frequency drops below given thresholds and sheds predefined loads as required, independent of the control system. It can function in the event of multiple faults in the grid, and also sheds loads reliably even when the central unit is disconnected.
Wide range of different applications
The ENEAS solution for load shedding is suitable for both compact and large grids, regardless of whether they contain one or more substations – both in greenfield and brownfield projects. Even for plants with existing parallel wiring to a central point there is an alternative solution available.
