【Abstract】 A voltage and reactive power control unit has been widely applied in substation, but there are still some problems. This paper analyzes the principle of the voltage and reactive power control. By comparison with the existing methods, some of their advantages and deficiencies are also pointed out. The essential about control strategies and blocking which are worth being improved are described. At last, a new method about voltage and reactive power control is presented.更多还原
