In the current era of surging digitalization, data centers, as key hubs of the information age, carry massive data storage and computing tasks, and their stable operation is crucial. And power supply is undoubtedly the "lifeline" of data centers. Any power failure may lead to data loss, business interruption, and incalculable losses. The Ankerui data center power monitoring solution has emerged as a robust D-brand to ensure stable and efficient operation of data center power.

Real time monitoring of Q direction, keeping track of power status

Ankerui's solution utilizes X-input sensors and smart meters to monitor the power parameters of the data center in real-time in the Q direction. From the voltage, current, and power factor of high and low voltage distribution cabinets, to the temperature and load rate of transformers, to the power consumption of various server cabinets, there is no omission. By monitoring nodes distributed in various corners of the data center, the collected power data is transmitted in real time to the monitoring backend. Management personnel only need to click the mouse to clearly see the overall power operation of the entire data center on the monitoring interface, truly achieving full control of the power status.

1. Overview

The power monitoring system realizes the low-voltage distribution system in the data center UPS、 Battery pack ATS/STS、 The precision distribution cabinet, power branch current, PDU cabinet power supply, and other important equipment are monitored, measured, recorded, and alarmed to real-time grasp the operation status and potential hazards of the power supply system, quickly eliminate faults, and improve the reliability of data center power supply.

2. Configuration plan

The following is a typical electrical single line schematic diagram of a large data center. In order to improve the reliability of power supply in the data center, 2 10kV mains power supplies are used, and 10 10kV diesel generators are configured as backup power sources. Install a 500kVA UPS on the 0.4kV side for power supply to precision air conditioning and precision distribution cabinets (intelligent small busbars).

Recommended Configuration

system architecture

The system adopts a distributed structure, with microcomputer protection devices, multifunctional instruments, transformer temperature controllers, DC screens, diesel generator control screens and other equipment connected to the intelligent gateway through RS485 bus or Ethernet. After protocol conversion and data processing, they are uploaded to the power monitoring system to achieve functions such as telemetry, remote signaling, remote control, and abnormal alarm.

Unveiling System Functions

Real time monitoring

The system has a user-friendly human-machine interface, displaying the operating status of distribution lines in the form of a primary distribution diagram. It monitors real-time electrical parameters such as voltage, current, power, power factor, and energy of each circuit, dynamically monitors the on/off status of circuit breakers, isolating switches, ground knives, diesel generator status, diesel liquid level, UPS status, battery information, and related fault and alarm signals of each distribution circuit.

● Detailed electrical parameter query

In the distribution diagram, detailed electrical parameters of the circuit can be directly viewed, including three-phase current, three-phase voltage, three-phase total active power, total reactive power, total power factor, forward active energy, and 24-hour phase current trend curve.

● Run the report

Query the operating parameters of each circuit or device at a specified time, and the electrical parameter information displayed in the report should include: phase current, three-phase voltage, total power factor, total active power, total reactive power, positive active energy, etc

UPS monitoring

The system collects UPS input, output, and bypass three-phase voltage, current, active power, power factor frequency, while monitoring UPS temperature, battery voltage, remaining time under current load, and other data. When abnormalities are detected, an alarm signal will be issued in a timely manner, and the alarm signal can also be classified according to the urgency level.

● Precision distribution cabinet monitoring

The system can display the electrical parameters of the incoming and feeder circuits in the precision distribution cabinet, including current, voltage, power, energy, and switch status. It can also set alarms and classify data, which is taken from the measurement module of the precision distribution cabinet.

Real time alarm

The power monitoring system has real-time alarm function, which can issue alarms for remote signaling changes such as distribution circuit breakers, isolating switches, grounding knife opening and closing actions, protection actions, accident tripping, and other events. The power monitoring system has real-time voice alarm function, and the system can issue voice alarms for all events.

● Historical event query

The power monitoring system can store and manage event records such as remote signal displacement, protection actions, accident tripping, as well as voltage, current, power, and power factor exceeding limits, making it convenient for users to trace the history of system events and alarms, query statistics, and analyze accidents.

● Electric energy statistical report

The power monitoring system supports the integrity of the quantity system with rich report forms. The system has the function of timed meter reading, summary and statistics. Users can freely query the electricity consumption of each distribution node at any time period since the normal operation of the system, that is, the statistical analysis report of the incoming power consumption of the node and the power consumption of each branch circuit.

● User permission management

The power monitoring system has set up user permission management function to ensure the safe and stable operation of the system. User permission management can prevent unauthorized operations (such as remote control operations, database modifications, etc.). It is possible to define login names, passwords, and operational permissions for users of different levels, providing reliable security for system operation, maintenance, and management.

● Remote control operation

The power monitoring system can remotely control the equipment within the entire distribution system. For example, maintenance personnel of the power distribution system can click on the corresponding circuit breaker remote signaling point on the main interface of the monitoring system to call up the remote control operation interface, and can promptly execute the corresponding operation commands of the dispatch system or the station.

● Network topology diagram

The power monitoring system supports real-time monitoring of the communication status of various devices connected to the system, and can fully display the entire system network structure; It can diagnose the communication status of equipment online, and automatically display the faulty equipment or component and its faulty location on the interface in case of network abnormalities.
