Distribution Automation - Necessity
  • To measure, protection control and monitor the
    components which are remotely located outside the
    substation
  • To integrate all substations within a circle and
    all such components which are remotely located
    outside the substation for performance analysis
  • To make the fault detection and automatic
    isolation
  • To integrate automatic meter reading to avoid
    manipulation and loss of revenue by integrating
    DA with Automatic Billing and Collection Centre
  • To maintain load shedding schedule automatically
  • To monitor network topology and network
    components (assets) using GIS (Geographical
    Information System).
  • To increase overall efficiency, reliability.
  • To make operation and maintenance easy
  • To save the time gap between a trouble call by a
    customer and actual service by integrating DA and
    Trouble Call Management

Power Quality (PQ) Drivers
  • Penalties by utilities drive harmonic filter
    sales
  • Transition to PC-based controls in manufacturing
    plants
  • IEEE standards foster the use of harmonic filters
  • Rising energy costs promote harmonic filter
    market
  • Reduced equipment life drives harmonic filter
    market
  • Losses in production due to tripping and
    shutdowns incite sales
  • Shift from electric to electronic loads spurs
    market growth
  • Environmental considerations instigate harmonic
    filter market
  • Increase in Nonlinear Loads ignites harmonic
    filter demand

Nonlinear, Harmonic Causing Loads
  • Electronic equipment such as PC
  • Battery chargers
  • Lighting dimmer controls
  • Fluorescent lights
  • Welders
  • Electronic ballasts
  • Printers
  • Photocopiers
  • Fax machines
  • VFD

All Above PQ damagers are mandatory for today's
developed World.
Hence PQ products is getting popular

PQ Products
  • Mechanical Switched Capacitor
  • Current based
  • p.f based
  • Thyristor Switched Capacitor (TSC)
  • STATCOM
  • LV (415V, extendable up to 690V), ratings
    110kVAR, 200kVAR, 500kVAR
  • LV (415V) 1-ph STATCOM, 100kVAR module
    paralleling for high power rating
  • MV (11kV and above) STATCOM
  • Voltage dip compensator

21
STATCOM
  • Input source current is sensed by DSP
  • DSP calculates harmonic components of the input
    current and reactive input power.
  • Counter harmonics and reactive power control is
    generated by the DSP driven Power Electronics and
    fed to power circuit
  • Thus the harmonics and reactive power is
    compensated by active filter

22
CGL STATCOM
  • 32 bit TI DSP controlling high speed IGBT
  • Algorithm on synchronous rotating reference frame
    i.e in DQ co-ordinates leading better harmonic
    attenuation ratio and better PF correction
  • Closed loop active filter with source current
    sensing
  • High attenuation of individual harmonics
  • Programmable selective harmonic elimination
  • PF compensation, leading as well as lagging
  • Selection between PF and harmonic compensation

  • Many units can be used in parallel i.e modular
  • Self current limit present, when overloaded.
  • Graphics LCD display for local monitoring and
    setting.
