Abstract

The configuration and the principle of operation of the static thyristor compensator of reactive power with the forced commutation and voltage addition for networks with a compensated neutral have been considered. The integrated indicators of the compensator energy process have been defined for the case when it is powered by a rectangular-shaped voltage in the case of independent control over the switching thyristors. At certain values of thyristor control angles, the specific losses of active power become less than the similar specific losses when the compensator is powered by a sinusoid voltage. This ensures its competitiveness relative to other static compensators.

A method of multicoordinate control over the static thyristor compensators with forced commutation has been proposed. It implies independent control over all switching thyristors in a compensator in accordance with the objective function of the system, which is determined under condition that the specific losses of active power do not exceed their economically justified level.

A circuit to control the static thyristor compensator with forced commutation and voltage addition has been suggested. The application of the circuit makes it possible to reduce active power losses in the compensator when controlling the reactive power and to execute independent control over the phase reactors. Real-time microprocessor control over all elements of the system makes it possible to enable the required algorithm for switching commutation thyristors and to implement multi-coordinate control over the compensator energy processes. An algorithm for operating the microprocessor system of the static compensator when controlling the reactive power has been constructed. The algorithm, due to an increase in the voltage addition coefficient during the action of a negative half-wave of supply voltage, makes it possible to reduce the specific losses of active power in the electrical network and compensator
