equipments, LT Capacitor Units. Dynamic compensation of Harmonics by
Harmonic Filter Panels (Tuned and Detuned Reactors), Active Filters
(OSF Harmonic Filters), Reactive Power Control Relays. Maximum Demand
Control Systems, Energy Management Systems. Reactive Power Compensation Electricity
suppliers charge for all the power they deliver not only the active
power needed to drive motors, etc, but also the reactive power needed,
for example, to maintain the magnetic fields of motors. Only part of
the reactive power is included in the price for electricity. If the
reactive power is generated by a power plant, the distribution system
and all the equipments have to be dimensioned to cope likewise.
The capacity thus, has to be much higher than is actually
needed. It is therefore sensible to generate the reactive power where
it is needed or at the Main Distribution Point.
The benefits are :
correct dimensioning of distribution system and equipment brings
savings at source. No need for reinforcement of transmission or
distribution systems. Cheaper electricity rates, no reactive power
charges.
Harmonic Filtering In
connection with reactive power compensation, power quality should also
be considered. Harmonic filtering reduces the risk of technical
faults and disturbances. Voltage distortion resulting from
harmonic currents are caused by inverters, DC drives, motors,
fluorescent lighting, converters, UPS, VFDs, arc furnaces etc. In
practice harmonic currents are everywhere. Harmonic filtering
brings a number of bonuses: • Disturbances
in telecommunications and data transmission are minimized. • Electronics
control systems, converters, motors and generators operate
without interruption and to their full capacity. • No
risk of overloading cables, nuisance tripping of relays or fuses. • Poor
power quality may remain unnoticed for a long time. Quality
deficiency may easily bring extra costs in the form of high
electricity bills and an oversized power system.
