Reactive Power-Voltage Integrated Control Method Based on MCR

In power system, the voltage pulsation and deficiency or surplus of reactive power will have a great effect on the quality of electric power supply. Through the appropriate and effective way of compensation, we can keep the balance of reactive power in the maximum degree by the maintenance of acceptable voltage. That's to say, quality of power supply can be improved greatly by the synthetic compensation of reactive power and voltage. This paper firstly describes the principles of synthetic compensation of reactive power and voltage, then introduces the analyzes the principle of magnetically controlled reactor-MCR in detail and derives the characteristics, lastly designs a controlling strategy of reactive power and voltage based on MCR, so as to achieve the goal of dynamic reactive power compensation.
