1. What is Complex Power of Generator under Power Angle Curve?

Complex Power of Generator under Power Angle Curve refers to the product of the RMS value of the phasor voltage and conjugate of the phasor current. It represents the total power in an AC circuit, including both real and reactive power components.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Complex Power (Watt)
• \( V_p \) — Phasor Voltage (Volt)
• \( I_p \) — Phasor Current (Ampere)

Explanation: The formula calculates the complex power by multiplying the phasor voltage and phasor current values.

3. Importance of Complex Power Calculation

Details: Complex power calculation is essential for analyzing power systems, determining generator performance, and understanding power flow in electrical networks under different power angle conditions.

4. Using the Calculator

Tips: Enter phasor voltage in volts and phasor current in amperes. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between complex power and apparent power?
A: Complex power includes both real and reactive components, while apparent power is the magnitude of complex power.

Q2: How does power angle affect complex power?
A: The power angle (δ) between voltage and current phasors determines the distribution between real and reactive power components.

Q3: What are typical units for complex power?
A: Complex power is measured in volt-amperes (VA), with real power in watts (W) and reactive power in volt-amperes reactive (VAR).

Q4: When is this calculation most useful?
A: This calculation is particularly important in power system analysis, generator operation, and stability studies under varying load conditions.

Q5: Are there limitations to this simple calculation?
A: For more accurate results in practical applications, phase angles and power factor should be considered in the complex power calculation.
