• Power quality measurement on low- and medium-voltage networks

Equipment

SIEMOS PQ II

SIEMOS PQ II is used to perform power quality measurements on low- and medium-voltage networks. The equipment enables, among others, detection of short circuits in the network, storage of instantaneous values of AC or DC signals (voltage, current, power), evaluation of voltage quality in accordance with EN50160, IEC61000-2-2 and IEC61000-2-4 standards, real-time frequency analysis up to 170 kHz, analysis of transients, study of electrical loads, evaluation of energy efficiency. The range of applications of the analyser is therefore wide and the possibilities of use in research and project work are correspondingly wide.

The instrument builds on the laboratory's existing range of measuring instruments and adds new functionalities. The most important added functionality is the UMTS connectivity of the instrument, which in practice allows remote access and real-time control of the measurement data acquisition and real-time modification of the data acquisition parameters.

Technical data

The instrument consists of a central data acquisition processor card in a suitable housing and ancillary equipment including a complete set of current probes, ancillary connection material, cable connections, UMTS modem and antenna, carrying case.
The instrument allows the following sampling intervals of the measurement quantities: instantaneous values from 200 ms to 3 sec, frequency measurement at 10 sec, instantaneous measurement n x sec (1 sec to 30 min free).

Other technical data:

• Analog input AC/DC: 24 Bit A/D converter, 40.96 kHz sampling frequency, frequency analysis from DC to 20 kHz;
• Digital input: accepts any external AC or DC trigger pulse (12 - 250 V);
• Amplifier card: 4 MHz, ± 5 kV level;
• Memory: 4 GB; expandable via SD card up to 32 GB;
• Connectivity: USB 2.0, Ethernet TCP/IP, WLAN/WiFi connection, RS232 (DCF or GPS clock);
• UPS: on - power supply up to 3.5 hours.

The rental price for the measuring equipment is EUR 150/day (VAT not included).

Strojna in programska oprema Typhoon HIL za izvajanje simulacij elektroenergetskega sistema v realnem času

Simulator je modularno zasnovana namenska strojna oprema, ki na podlagi principov vzporednega procesiranja omogoča izračune kompleksnih elektromagnetnih in elektromehanskih pojavov v elektroenergetskem sistemu z visoko resolucijo (od 0,5 mikrosekunde) in je uporabniku na voljo v realnem času z visoko natančnostjo. To omogoča izvedbo simulacij v zaprti zanki s poljubno strojno opremo (angl. Harware In the Loop – HIL), kar je najboljši možni približek preizkušanju opreme v realnem elektroenergetskem sistemu. Razpon možnih aplikacij uporabe HIL simulatorja je velik, npr. preizkušanje regulacijskih naprav, zaščitnih naprav, sistemskih ukrepov, prototipov, itd..

Tehnični podatki

Simulator je sestavljen iz osrednje procesorske kartice, ki temelji na FPGA tehnologiji, v ustreznem ohišju in pomožne opreme, med drugim več analognih in digitalnih vhodov/izhodov. Poleg strojne opreme je sestavni del simulatorja tudi programska oprema Typhoon HIL Control Center, ki služi kot vmesnik do strojne opreme in preko katere lahko upravljamo s simulatorjem.
