WinPQ

Electrical supply grids are currently subject to profound change processes. Active power electronics, as found in switching power supplies and inverters, is omnipresent. To achieve CO2 reductions, small, renewable energy generators are being built everywhere. Large, conventional power plants are disappearing. Phenomena such as load flow reversals, overloads, voltage band increases at entry points and asymmetries are now part of daily business. This can be a problem, for example, for highly optimised EDP facilities, but also for industrial control systems that are sensitive to short-term supply failures, harmonics and transient events. The stability of the network may even be in question.

It was only in 2014 that the German Supreme Court determined that electricity is subject to the Product Liability Act. Thus: distribution grid operators are liable for damages caused by poor power quality. With the combination of the Class A-certified measurement device family PQSys and the fully automated server solution WinPQ, A. Eberle offers a comprehensive system for watertight records of power quality. It makes users able to document, assess and demonstrate power quality continuously at any time. Faults can be recognised early on, their causes determined and eliminated. All built-in fault logs and mobile network analyzers from A. Eberle are supported by a SQL database server, to which they can be connected across networks and even in great numbers. Communications connection via control protocols such as IEC 61850, Ethernet, 3G, 4G and analogue modems. The most important thing: the WinPQ software is on top form where large data quantities need to be handled. Automated reporting assistants will fully automatically comb the data for you and report only the most important facts. You can receive standard reports and alarms by email if you desire, or have them laid down in standard formats such as Comtrade, PQDiff or PDF in network drives. Further action is not required. With our well-tuned system solution, consisting of hardware and software, you can keep an eye on power quality at any time.
