PROBLEMS
Harmonics Mitigation
A pure sinusoidal waveform is an ideal system , but due to non-linear loads , electronics based systems, constant switching loads, automated sytems , DC drives and other loads the power system is injected with harmonics with frequencies in multiples of fundamental , this causes distortion in voltages and pollutes the power quality , leading to heating in cables, transformer , improper operation of systems and switchgear failure. These needs to be addresed as major industries face loss in production due to failure of electrical equipments
Power Factor Improvement
Power Factor indicates how efficiently electric power is used in a system. Due to inductive loads ,operation of dynamic loads ,low loads & imbalance in power systems the PF is adversly affected,leading to utilities imposing penalties. The improvement PF is not only for cutting down energy costs ,but to use energy efficiently & reduce bad environmental effects .
Unbalance Compensation
Unbalance occurs in the power systems when the voltages and currents in the three phases are unequal, this is due to the unequal load distribution in the electrical network. These causes degradation of equipment’s, cable derating, inefficient operation, tripping of equipment, fluctuating torques in the motors etc.., INPHASE has provided special solution to tackle L-L unbalance & negative sequence where the specifically designed controller to measure the components of each line and counteract the unbalance.
KVAH Billing Reduction
KVAh billing is incorporated to ensure that customers use power efficiently with reduced losses .The reactive power is drawn from the grid as per the process of load operation and type of loads like drives, motors, non-linear & inductive loads, which leads to additional billing charges.
Floating Grid PF Correction
Major production & energy industries have their own source of power for uninterrupted power and donot rely on the electricity board completely . The dynamic reactive power (KVAr) is drawn from the grid without a proper compensator meeting the KVAr demand is a major challenge. InPhase Active compensators are proven to be beneficial & efficient in these complex operations. Know more about solutions for floating grid.
