Abstract

This paper considers a Matlab-Simulink Model of a system for a load reactive power compensation with consisting of a thyristor-controlled binary switched capacitors (TBSC) and a thyristor controlled reactor (TCR). The capacitors ensure stepwise compensation of reactive power, while the controlled inductance makes it possible to achieve smooth changing of the resulting compensating power within the limits of the minimal capacity in the binary capacitors series. The model uses a very simple algorithm of capacitor control, provided with a logical system that prevents current surges in the moments when capacitors are being connected to the network. The switching of capacitors is set by a closed system for maintenance of the maximal power coefficient. To regulate the inductance in TCR, an invariant system of phase control is used, which maintains the unit value of the power coefficient in the network irrespective of load changes. The realization of the system in the model is maximally close to its possible hardware realization. The functioning of the model has been tested in a wide range of variation of the reactive load power, and the testing confirmed the efficiency of combining a switchable series of binary capacitors and a thyristor-controlled inductance when using the proposed control algorithms.
