Activity coordination of capacitor banks and power transformer controllers in order to reduce power losses in the MV grid

One of the main issues related to the optimization of the MV (middle voltage) network is to reduce losses of active and reactive power. Lower losses of active and reactive power give not only economic advantage, but also improvement of energy quality. The object of regulation that can be used for these purposes are transformer with On-Load Tap Changer and capacitor's banks. This paper presents results of analysis of the possibility of using capacitor banks installed inside the MV network (in industrial consumer) in order to minimize power losses in the power network. The results of analysis allowed to determine which of the criteria adjustment: constant voltage or maintain constant values of power factor tg fi , in individual buses is better. It was also pointed to the necessity of the coordination between actions of regulators of the transformer and capacitor banks.
