Parameterization and Analysis Software

DIGSI 5

1.4.1
Description
DIGSI 5 is the versatile engineering tool for parameterization, commissioning, and operating all SIPROTEC 5
devices. Its innovative user interface includes context-sensitive user instructions. Simple connection to the
device via USB and Ethernet IF enables you to work with a device easily and efficiently. The full capabilities of
DIGSI 5 are revealed when you connect it to a network of protection devices: Then you can work with all of the
devices in a substation in one project.
DIGSI 5 offers superior usability and is optimized for your work processes. Only the information you actually
need to carry out your tasks is shown. These can be reduced further via expanded filter mechanisms. Consis-
tent use of sophisticated and standardized mechanisms in the user interfaces requires less training. DIGSI 5 is
tailored to specific requirements. The free software variant DIGSI 5 Compact offers everything that is required
for a single device. The DIGSI 5 Standard Version is suitable for complex scenarios with several devices.
DIGSI 5 Premium contains the full functionality you need to raise your productivity to a new level.

SICAM PQS/SICAM PQ Analyzer

Description
Siemens SICAM PQS allows all fault records and network quality data (PQ data) to be analyzed in one system.
The protection of power distribution equipment is crucial in assuring a reliable electricity supply. The user
expects full availability of electrical energy at a consistently high standard of quality. Thus, for power-system
protection, for example, it is becoming increasingly difficult to distinguish between critical load cases and
short-circuits with minimum fault currents. The demands on optimum use and the corresponding parameteri-
zation of protection devices are rising. Intensive evaluation of available information from secondary equip-
ment using fault recorders is therefore essential. This is the only way to ensure today's currently high levels of
reliability and availability in electricity transmission and distribution systems for the future as well. Addition-
ally, the growing use of power electronics often has a noticeable impact on power quality. The result is poor
power quality, which can cause interruptions, production outages, and high follow-up costs.
Compliance with the generally valid quality criteria for electricity-supply systems as defined in standards (for
example, EN 50160) is therefore vital. The basis must be reliable recording and assessment of all quality
parameters. Weak points and potential fault sources can be identified early on and systematically eliminated.
With the software solution SICAM PQS, Siemens is setting new standards: For the first time, it is possible to
evaluate and archive centrally all network quality data from the bay level with one integrated software solu-
tion in a vendor-neutral manner. This gives you a quick and uncomplicated overview of the quality of your
system. With SICAM PQS, you can keep an eye on all relevant data: Fault records as well as all network quality
measured data. For combined applications, SICAM PQS is also easy to expand to a substation automation
system.
