SICAM PAS
Power Automation System – Substation automation system, modular in design and based on the Substation
Controller SICAM SC and the HMI system SICAM WinCC.
SICAM PQ Analyzer
The SICAM PQ Analyzer is used for the following purposes:
- Displaying data measured by a PQ device
- Assessment of these data according to power quality criteria by the SICAM PQS System (...).
The various views of the SICAM PQ Analyzer provide the means for evaluation of archived PQ measured data
and system incidents.
- Incident explorer
- PQ Inspector
- PQ Explorer
- Report browser
- Grid code viewer
SICAM PQS
With SICAM PQS, all fault records and power quality data in a system can be analyzed.
SICAM SCC
The HMI system SICAM SCC (serial communications channel) graphically displays the state of your network.
SICAM SCC visualizes alarms and messages, archives the network data, provides the option of intervening
manually in the process and manages the system rights of the individual employees.
SIGRA
The SIGRA component supports you in analyzing failures in your power system. It graphically conditions infor-
mation recorded during the failure and calculates additional supplemental quantities such as impedances or
RMS values, from the supplied measured values making evaluation of the fault record easier for you. The
quantities can be shown as desired in the diagrams of the following views: time signals, phasor diagrams,
locus diagrams and harmonic components. In addition, you may add more fault records to the failure evalua-
tion, for example, from the opposite end of a line, and synchronize these. SIGRA is also suited to evaluate fault
records of devices from other manufacturers.
SIGUARD PDP
SIGUARD PDP (Phasor Data Processing) is software for monitoring the status of power transmission in exten-
sive power systems. When critical states are approached (frequency stability, voltage stability, transmission
stability, and power swing), this is detected early and displayed. The threshold at which a critical state is
reached and requires intervention can be defined and subsequently changed at any time. In addition,
SIGUARD PDP supports you in the analysis of the power system. Weak points and fault sources can be identi-
fied and eliminated early on. SIGUARD PDP works together with PMUs (phasor measurement units). These
measuring devices are installed in the power distribution systems and connected to the current and voltage
transformers. Time synchronization via GPS having an accuracy of < 5 μs enables the PMUs to acquire the
measured values with amplitude and phase as phasors (indicator values) with high precision and to transmit
them via the communication interface. These time-synchronized measured values from regionally widely
distributed measuring points can be collected and evaluated using SIGUARD PDP.
SIMEAS R
SIMEAS R is a digital fault recorder (like the 7KE85) used primarily in power plants, transformer substations,
medium-voltage systems, high-voltage systems, systems for very high voltages and in industrial complexes for
quality assurance and for monitoring secondary and primary facilities. It measures and documents indicators
defined in international standards (EN 50160). Weak points can be reliably and quickly identified due to its
high degree of functionality. In the event of a fault, all relevant signals are recorded with pre-event history,
