Abstract: The increment of adjustment of transformer substation is always ignored with the traditional voltage and reactive control in transformer substation. Especially when the adjustment to the tap of transformer or the group of reactive compensation equipment is occurred near the critical value, the oscillation is easily generated. To overcome the default, the traditional method is improved in this paper. Because the increment that generated by adjustment of voltage and reactive power can change the value of reactive power of reactive compensation equipment and the voltage value which transformer supplies, the voltage and reactive control adopts the method that considers the increment of adjustment of transformer substation. With calculating the taps of transformer and the value of reactive power, the rapid and accurate adjustment can be implemented.
