IV. Muhimman Ƙananan Binciken Tsari
- Tsarin Ƙarfin Da Ƙarfi:
- Formula: Total Initial Investment / Annual Net Benefit (Electricity Savings + Penalty Avoidance)
- Industry Typical Value: 1-3 years (depending on electricity tariff level and power factor condition)
- Net Present Value (NPV):
- Total present value of project benefits considering the time value of money.
- Calculation: NPV = Σ(Annual Net Cash Flow / (1+Discount Rate)^t) - Initial Investment
- Decision Criterion: NPV > 0 indicates economic feasibility.
- Internal Rate of Return (IRR):
- The discount rate that makes the project NPV equal to zero, reflecting capital efficiency.
- Industry Benchmark: Typically higher than the company's cost of capital or bank loan interest rates.
V. Risks and Economic Optimization Strategies
|
Risk Factor |
Economic Impact |
Optimization Strategy |
|
Harmonic Environment |
Accelerates capacitor damage, increases maintenance cost |
Install series reactors or harmonic filters |
|
Overcompensation Risk |
Causes voltage rise, potential equipment damage |
Automatic grouping switching system + Reasonable capacity sizing |
|
Capacitor Lifespan |
High temperatures shorten lifespan, increase replacement cost |
Choose high-quality brands, ensure ventilation/cooling |
|
Load Fluctuations |
Fixed compensation struggles to match demand changes |
Adopt intelligent automatic reactive power compensation (e.g., SVC/SVG) |
