METHOD OF DETERMINING PARAMETERS OF LINEAR CAPACITOR BANK FOR DESIGNING ITS MODEL Russian patent published in 2008 - IPC G01R25/00 

FIELD: physics; measurements.

SUBSTANCE: method involves measuring instant values of current and voltage. The array of readings of instant values of current and voltage are obtained in the same instants in time t_j=t₁,t₂,...,t_N, with sampling interval of , where T is the period of the current/voltage signal; N is the number of readings for a period T. The values are then stored as current values, and the voltage difference ΔU₁₂(t_j) is determined for the voltage difference between the end and the beginning when there is longitudinal connection of the capacitor bank or the voltage difference between the beginning and the end when there is transverse connection. The digital readings of the voltage difference are then stored as current readings. The voltage differences are then differentiated: ΔU'₁₂(t_j) and ΔU'₁₂(t_j+1). The value of the voltage loss ΔU'_12P(t_j) is then calculated: , the value of the reactive component of the current i_C(t_j) is then determined: The capacitance of the capacitor bank C_i is determined as the ratio of the reactive component of current i_C(t_j) to the calculated voltage loss ΔU'_12P(t_j). The value of the active resistance of the capacitor bank R_i is determined: The average values of the active resistance and capacitance of the capacitor bank for one period are calculated. These values are the final results.

EFFECT: simplification, increased accuracy and information content of measuring instant values of current and voltage.
