The balance is reactive voltage level to ensure the basic conditions 。 Voltage power quality is one of the important indexes , Voltage quality of power system stability and the safe operation of electrical equipment, wiring losses, industrial and agricultural production safety, product quality, electricity intensity and the life of the people will have a direct impact on electricity consumption. Reactive power is affecting the voltage quality was a major factor in the quality of voltage and reactive power are inseparable. To a distribution line as an example, Comparison of several methods pensation capacity of pensation capacity of the distribution of the best methods of calculation. At the end of t his paper , introduced a voltage and reactive power control system of three voltage substation control system and VQC substation control device Principle .
