Power Monitoring (EDCO)

The Electricity Regulatory Commission (ERC) was established in 2001 under a government decree. This establishment was part of the government privatization plan.

Technology Integration and under the agreement with EDCO and the ERC, developed and installed a Power Quality Monitoring System at EDCO / Aqaba.

The system was developed on a combination PXI / SCXI system. PXI controller, embedded real-time operating system, with LabVIEW Real-Time was used to acquire waveforms at the substation location. While a server that was located at the central office was connected to PXI machine using industrial wireless Ethernet.

System was designed to meet the following requirements:

• • High speed time logging
  • Wireless, Ethernet connectivity with client/server architectures
  • Data Acquisition, Data Analysis, and Data Presentation all in one platform
  • Synchronized Measurements for electrical power voltages, currents, and digital switchgear
  • Single line Diagram representation
  • Power Quality Measurements including power factor, power metering, harmonic distortion, and transient events including sags, swells, and impulses
  • Extensive graphical plotting capabilities including polar plots, time waveform plots, and statistics
  • Alarming, Reports, and Data Management
  • Sequence of Events Recorder
  • Open and flexible approach, scalable to future systems
  • Integrated platform based on commercial off-the-shelf tools

Following are the measurements realized at the substation:

• • RMS Voltage and current
  • Voltage Harmonics, and Total Harmonic Distortion.
  • Apparent Power (VA), Active Power (Watt), Reactive Power (VAR)
  • Power Factor and Power Factor Distortion
  • Current Phase: Lead or Lag
  • Voltage and current Waveform Chart
  • Phase Angle Polar Plot
  • Voltage and current RMS Trend
  • Transients Recording
  • Earth Fault Indication
  • Measurements based on Voltage & Current readings
