ABSTRACT:
A process for parallel control of tap transformers in which individual voltage regulators of parallel operating transformers are connected to a single parallel processor by serial data lines and the measured values of the voltage and current amplitudes and the phase angles are transmitted by the voltage regulators to the parallel processor, an interference variable for each voltage regulator is calculated in the parallel processor from the partial load current and the circulating reactive current and is transmitted with the partial load current by the serial data lines to the voltage regulators, and each voltage regulator then calculates an LDC variable for load drop compensation, by summing the measured voltage, the received interference variable and the LDC variable provides a controlled variable or voltage value which constitutes the new set point with respect to which the voltage regulator then controls the transformer to which it is assigned.
