3.5.3 Energy/Quadergy

Energy and quadergy over the integration period can be calculated from the metrology output registers:

Where, x = [A, B, C] and:

• f_s = 4000 Hz is the output integration sample rate
• P_x is active power of all harmonics of phase x
• Q_x is reactive power of all harmonics
• S_x is apparent power of phase x
• P_x_F is active power of fundamental harmonic
• Q_x_F is reactive power of fundamental harmonic
• S_x_F is fundamental apparent power of phase x
• ACC_P_x is the accumulated active power quantity for all harmonics
• ACC_Q_x is the accumulated reactive power quantity for all harmonics
• ACC_P_x_F is the accumulated active power quantity for fundamental harmonic
• ACC_Q_x_F is the accumulated reactive power quantity for fundamental harmonic
• ACC_I_x is the accumulated fundamental and all harmonics current quantity
• ACC_V_x is the accumulated fundamental and all harmonics voltage quantity
• ACC_I_x_F is the accumulated fundamental harmonic current quantity
• ACC_V_x_F is the accumulated fundamental harmonic voltage quantity
