Power Quality (PQ) Improvement Systems on LT distribution:
Benchmarking of PQ and Various methods & merits.
Abstract
Various aspects of Power Quality need to cater to issues like:
Voltage Sags and Swells
Momentary mains cycles loss.
Voltage surges and High frequency noise /
disturbance (sometimes called as transients or
glitches)
Current surges and high fluctuation of load
current (normally reflects onto voltage problems)
Current Harmonics and consequential Voltage
Harmonics.
Inter-harmonics on Current and Voltages.
Neutral floating or shifting.
Earthing Problems.
Power Outages and effect of Auto-Reclose
system.
Load Shedding (Specifically with countries
where demand is much higher than generation)
Power frequency Variations.
And some issues that are indirectly related to Power
Quality:
Reactive Power Compensation issues.
Load unbalance between the phases and
Neutral loading.
System Resonance ? Parallel and Series.
Maximum Demand control (kVA demand and
kW demand).
