1. What is B-Parameter Using Receiving End Reactive Power Component?

The B-parameter is a generalized line constant in transmission line analysis, also known as short circuit resistance. This calculation specifically determines the B-parameter using the receiving end reactive power component in a transmission system.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ B = \frac{((V_r \times V_s) \times \cos(\beta - \angle\alpha)) - (A \times (V_r^2) \times \cos(\beta - \angle\alpha))}{Q} \]

Where:

\( B \) — B parameter (Ohm)
\( V_r \) — Receiving end voltage (Volt)
\( V_s \) — Sending end voltage (Volt)
\( \beta \) — Beta B-parameter phase (Radian)
\( \angle\alpha \) — Alpha A-parameter phase (Radian)
\( A \) — A parameter (dimensionless)
\( Q \) — Reactive power (Watt)

Explanation: The formula calculates the B-parameter by considering the voltage relationship, phase differences, and reactive power component in the transmission line.

3. Importance of B-Parameter Calculation

Details: Accurate B-parameter calculation is crucial for transmission line modeling, power flow analysis, and system stability studies in electrical power systems.

4. Using the Calculator

Tips: Enter all values in appropriate units. Voltages and reactive power must be positive values. Phase angles should be entered in radians.
