    Wide Area Measurement System

    Uploaded by

    VIGNESH DHANASHEKHAR
    The Wide Area Measurement System (WAMS) collects high-volume data from across the power grid using new technologies like phasor measurement units and phasor data concentrators. WAMS has two major functions: obtaining data and extracting value from it through analysis tools and algorithms. This advanced measurement system provides critical information and situational awareness to support functions like real-time monitoring, oscillation detection, fault location, and stability assessment in order to improve reliability and avoid blackouts.

    WIDE AREA MEASUREMENT

    SYSTEM
    The WAMS effort is a strategic effort to meet critical information needs of the changing
    power system.
    • It is an advanced measurement technology to collect information.
    • It is based on the new data acquisition technology.
    • The WAMS has two major functions:
    1. Obtaining the data
    2. Extracting value from it
    WAMS’s Major Functions
    • Getting the data is accomplished with a new generation
    of data recording hardware that produces high volume
    recordings.

    • Data is extracted and analyzed using several analysis


    tools and algorithms.
    Major Components of WAMS
    • Global Positioning System(GPS)
    • Phasor Measurement Unit(PMU)
    • Phasor Data Concentrator(PDC)
    WAMS Architecture
    Necessity of WAMS
    a. Immediate actions can be taken if some failures are detected
    when the constant monitoring applications are available.

    b. Early warning system: to improve the reliability

    c. To avoid regional blackouts


    Applications of WAMS

    • Power system Real Time Monitoring


    • Power system Oscillations
    • Fault detection/Location of power systems
    • Power system voltage stability
    • Electric distributed power system
    • Power system state estimation
    WAMS in Smart Grid
    • Wide-area measurement systems (WAMS) in smart grid can be
    defined as a system that captures measurements in the power
    grid over a wide area and across traditional control boundaries,
    and then uses those measurements to improve grid stability and
    events through wide-area situational awareness and advanced
    analysis.

    • WAMS provides visibility that is based on real-time data


    streamed from Phasor Measurement Units (PMU). A host of
    WAMS software applications use this data to provide context-
    specific information, presented through an intuitive user
    interface.
