How it was calculated
- Connected equipment load = 2,000 kW
- Demand = 2,000 × 0.6 = 1,200 kW
- Motor share = 60% → 720 kW (drives natural PF 0.82)
- Reactive compensation: Qc = 1,200 × (tanφ₁ − tanφ₂) = 443 kvar
- Harmonic-source share = 25% → 300 kW → Ih = 137 A (30% THDi)
- Loads: P=2,000 kW, PF 0.82, 8 circuits
- Demand: 2,000 × 0.6 = 1,200 kW
- Transformer: S = 1,200 ÷ 0.95 = 1263.2 kVA → 1,600 kVA standard
- Loading: 1,263 ÷ 1,600 = 79% (good range)
- Voltage regulation: 79% × 4% × sinφ ≈ 1.0% at full load
- HV: In 92.4 A, Isc 28.9 kA → KYN28A-12-630-315
- LV: In 2309 A, Isc 53.5 kA (Xfmr Z 4% + system 0.3%) → GGD-2500, 2 feeder panel(s)
What drives the cost
- Equipment — the transformer/switchgear/inverter is the largest single line item.
- Storage (where applicable) — batteries are the biggest swing factor.
- Copper & freight — copper-linked cabling and freight shift landed cost ±5–10%.
Frequently asked questions
What demand factor applies to an industrial park?
An industrial park with many factories never runs every machine simultaneously; a demand factor of 0.55-0.7 is typical. A 2000 kW connected load at 0.6 kd and 0.9 pf gives ~1330 kVA demand, so a 1600 kVA transformer or two 800 kVA units suit. The calculator uses demand factor and motor share to size the MV/LV plant.
How much harmonic filtering does a factory-heavy park need?
When 60% of load is motors on VFDs and 25% is non-linear (rectifiers, UPS), THDi can reach 15-25%. IEEE 519 limits THD to 5-8% at the point of common coupling, so a detuned capacitor bank (7% reactor) or APF is required. The calculator sizes compensation and detuning from the harmonic share.
What is the standard MV/LV architecture for an industrial park?
Typical architecture: 10 kV (or 35 kV) utility feed -> ring or radial MV switchgear -> one transformer per factory or block -> 0.4 kV switchboards -> motor control centers. A 10 kV ring with RMUs along the ring offers N-1 supply. The calculator sizes the transformers, switchgear and compensation for the aggregated park load.
How do I allocate transformer capacity per factory?
Give each factory its own transformer sized to its demand plus 20-25% headroom, or share one large transformer for small tenants. Separate transformers isolate faults and simplify metering, but shared units cost less. The calculator aggregates the park demand and shows the single-transformer and split-transformer options.
What power factor should an industrial park maintain?
Utilities usually require 0.9-0.95 power factor and levy penalties below ~0.9. Industrial parks with motor-heavy load typically start at 0.75-0.85 and add capacitor banks to reach 0.95. The calculator computes the required kvar compensation to correct from measured pf to target and sizes the LV capacitor bank.
What redundancy does a park MV network usually provide?
A ring-main MV network with normally-open tie provides N-1 redundancy: any cable or RMU fault is isolated and load restored from the other direction. Radial feeders are cheaper but lose supply on a fault. The calculator's architecture notes cover ring vs radial options and their reliability trade-off.
