Energy Quality Assessment Software
Electrical grids are currently undergoing radical change. Active power electronics as used in switching power supplies and inverters are ubiquitous. To achieve CO2 reduction goals, small, renewable energy generators are being installed everywhere. Big, conventional power plants are disappearing.
Phenomena such as backfeeding, equipment overloads, voltage spikes at feed-in points and asymmetries are part of day-to-day business. This is a problem for highly optimized data centres and industrial controls that are sensitive to short dips in supply, harmonics and transient events. Even the stability of the grid is vulnerable.
With the combination of the Class A-certified PQSys family of measuring devices and the fully automated WinPQ server solution, A. Eberle offers a comprehensive voltage quality system that will stand up in court. It enables users to document, evaluate and prove the quality of the voltage at any time. Faults can be detected, the source determined and the cause remedied early.
All of the installed fault recorders and mobile grid analyzers from A. Eberle are supported and can be connected across grid levels, in large numbers, to an SQL database server.
Communication over SCADA protocols, such as IEC 61850, Ethernet, 3G/4G and analogue dial-up modems is possible. The WinPQ software is at its absolute best when it comes to controlling large amounts of data. Automated reporting assistants automatically explore the database and report only the things you need to see. You can receive standards reports and alerts by email or in standard formats such as Comtrade, PQDiff or as a PDF document on the hard disk. It’s that easy!
Our fine-tuned hardware and software solution enables you to keep an eye on the voltage quality at all times.
“WinPQ System solution for all installed fault recorders, power quality monitoring devices and mobile grid analyzer by A. Eberle Continuous power quality monitoring – from high voltage to the end customer as a system. Intuitive despite a large amount of data.”
The philosophy behind the WinPQ system: An ‘All-in-one’ system overview
The WinPQ client-server software with database is an intelligent system solution that automatically monitors faults and the grid quality in parallel across several measuring devices. Different device versions are available for different requirements and voltage levels. The evaluation software supports all installed A. Eberle fault recorders. TCP/IP, fibre optics, RS-232, 3G, 4G and analogue modems can be used to communicate with the devices.
In addition, all of the data measured by the mobile grid analyzers can be imported into the database and correlated with the data on the installed devices.
The database is generally installed on a server to guarantee it’s always running. The database supports any number of concurrent WinPQ clients.
WinPQ can be used with the following databases: MySQL, Maria DB, MS SQL and Oracle DB.
The system’s key features include;
The WinPQ database analysis software enables you to easily create abstract views of many measurands that have no time correlation: from the measured data’s timing diagrams to highly accurate error logs.
A click of the mouse is all that is needed to generate an EN 50160 report: with millions of records across the whole measuring area. If a measurement is exceeded, the time behaviour (cyclical data) can be directly displayed.
Permanently archive several years of cyclical data timing diagrams. Direct link with sampling values if thresholds are exceeded.
Highly accurate analysis across the 10 ms TRMS logs and sampling values with up to 40.95 kHz.
½ period recorder TRMS average values of all voltages (phase-to-phase and phase-to-ground), currents, active power, reactive power, apparent power and frequency.
