Power qualityの問題は、IT機器に深刻な損傷を引き起こす可能性があります。SiemensのSolutionsは、高度な分析技術を用いて異常をリアルタイムで測定・分析・検知し、障害の防止、ダウンタイムの削減、信頼性の高い無停電運転の確保を実現します。
チャレンジ
Power qualityはデータセンターの稼働時間において見過ごされがちな要素です。大規模な建物では再生可能エネルギーが電力系統の変動性を増大させ、オンサイト発電は配電をより複雑にします。Power qualityの低下は機器の故障や高額なダウンタイムを引き起こす可能性があります。
解決策
Power quality監視をEMSまたはBMSシステムに直接統合することで、障害の予見が可能になります。電力品質計測器が異常を検知し、このデータをEnergy managementシステムに送信することで、事前対応を可能にします。
電力配電網の様々な地点にPower quality Metersを設置し、電圧、高調波、フリッカー、過渡現象などの重要パラメータを測定します。
収集したデータを評価し、電気エネルギーの品質が許容基準を満たしているかどうかを判断します。
規格からの逸脱を検出し、電圧変動や高調波などの潜在的な問題を指摘します。
Reducing harmonic distortion and other disturbancesminimizes energy losses and improves the overallefficiency of electrical equipment.
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.
SENTRON Powermanagerで、ネットワーク全体の電圧、高調波、フリッカー、過渡現象を測定し、稼働時間を保護します。データを分析して電力品質が要求基準を満たしていることを確認し、信頼性を高めます。電圧変動や高調波を早期に検知することで、高額な故障を回避します。継続的な監視とリアルタイムアラートにより迅速に対応し、障害を管理します。さらに、高度な分析機能で問題を運用に影響する前に予防し、常に一歩先を行くことができます。
Whether you’re building a new data center or modernizing an existing one, Siemens provides the expertise, software, hardware, and services to manage and analyze power quality issues in your network.
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.
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.
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.
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.
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!
