ANVENDELSE I DEN VIRKELIGE VERDEN

Power quality-analyse og -styring

Power quality-problemer kan forårsage alvorlig skade på dit IT-udstyr. Siemens' solutions måler, analyserer og registrerer uregelmæssigheder i realtid ved hjælp af avancerede analysefunktioner til at forhindre forstyrrelser, reducere nedetiden og sikre pålidelig, uafbrudt drift.

Udfordring

Power quality er en ofte overset faktor i datacentrets oppetid. I store bygninger øger vedvarende energi nettets volatilitet, og generering på stedet gør distributionen mere kompleks. Dårlig power quality kan forårsage udstyrsfejl og dyr nedetid.

Løsning

Power quality-overvågning integreret direkte i dit EMS- eller BMS-system hjælper med at forudse forstyrrelser. Power quality-instrumenterne registrerer uregelmæssigheder og sender disse data tilbage til energy management-systemet, hvilket muliggør proaktiv handling.

Måling

Installer power quality meters på forskellige punkter i strømdistributionsnettet for at måle kritiske parametre såsom spænding, overtoner, flimmer og transienter.

Analyse

Evaluer de indsamlede data for at afgøre, om den elektriske energikvalitet overholder acceptable standarder.

Identifikation

Registrer afvigelser fra standarderne, der indikerer potentielle problemer som spændingsudsving eller overtoner.

Improve energy efficiency​

Reducing harmonic distortion and other disturbancesminimizes energy losses and improves the overallefficiency of electrical equipment.​

Increase transparency

An integrated BMS and EPMS delivers visibility into electrical, cooling, and environmental performance, enabling operators to correlate disturbances, run analytics, detect anomalies faster, and manage infrastructure holistically.

Med SENTRON Powermanager kan du værne om oppetiden ved at måle spænding, overtoner, flimmer og transienter i hele netværket. Opnå større stabilitet ved at analysere data for at bekræfte, at energikvaliteten opfylder de påkrævede standarder. Undgå dyre fejl ved at registrere spændingsudsving eller overtoner på et tidligt tidspunkt. Du kan handle hurtigere med kontinuerlig overvågning og alarmer i realtid, så du kan for at håndtere forstyrrelser. Og hold dig på forkant med avancerede analyser, der afbøder problemer, før de påvirker driften.

Consult with experts

Discuss operational goals, uptime targets, and key performance indicators with experts such as Siemens PTI consultants. Identify where power quality measurements are required, such as grid infeed, automatic transfer switches, UPS systems, distribution units, cooling systems, and server racks.

Plan and design your solution

Define the power quality monitoring architecture and determine optimal placement of measurement devices. Ensure the design supports relevant standards, redundancy requirements, and open communication protocols such as IEC 61850 or Modbus TCP.

Deploy and scale your solution

Install power quality instruments such as SICAM Q100/Q200 at critical points in the power distribution network to capture parameters including harmonics, voltage sags and swells, transients, and frequency variations.

Monitor, analyze and report

Use SENTRON Powermanager with the PQ Advisor module to visualize power quality data, analyze disturbances, and create reports based on EN 50160. Dashboards support real-time event tracking, ITIC diagrams, and harmonic analysis. Integration with Desigo CC combines EPMS and BMS data.

Case Study

Power quality recorders connected to the BMS

Company: Greenergy Data Centers

Location: Estonia

Siemens solutions: Integrated BMS-EPMS, power quality, white space cooling optimization (WSCO), low voltage power distribution

With their own 110 kV substation feeding power directly from the grid, Greenergy Data Centers implemented an integrated BMS–EPMS platform to monitor their power quality across HV/MV, LV, UPS, and third-party devices. The EPMS is connected to the network provided by their customers, and it all communicates with the BMS system.

Siemens provided not only the necessary hardware and software, but also the technical solution consulting throughout the project. Learn more!
