Formula Explanations:

Parameters Explained:

1. Voltage (kV): This represents the electric potential difference and is usually given in kilovolts (kV). In substations, voltage level is crucial as it directly impacts the infrastructure required.

2. Power (MW): Power is the rate at which electricity is delivered to or from the substation and is generally measured in megawatts (MW).

3. Demand Factor (%): This is a percentage factor that represents the expected load usage or peak demand over time relative to the maximum possible load. For example, a demand factor of 80% means that the substation typically operates at 80% of its maximum load capacity.

Example Formula:

The formula used here is:

BNR = (Power × Demand Factor) / (Voltage × 1000)

Numerator (Power × Demand Factor): This combines the actual power requirement of the substation with the demand factor. By multiplying these, you obtain an adjusted power value that reflects real-world demand.

Denominator (Voltage × 1000): Voltage is scaled up by 1000 to ensure unit consistency since Power is in MW and Voltage is in kV.

Example Calculation:

Suppose:

  • Voltage = 20 kV
  • Power = 50 MW
  • Demand Factor = 80%

Substitute these into the formula:

BNR = (50 × 80) / (20 × 1000) = 0.20

So, the BNR would be 0.20 based on this specific setup.
