Analysis of the Status of Voltage and Reactive Power Control in Jiangsu 220 kV Grid

Firstly,the data of voltage,active and reactive power,power factor etc. are statistically compared,and then the method of reactive power balance is used for analysis on the lack of reactive power. Therefore the status of voltage and reactive power control in Jiangsu 220 kV power grid is analyzed from the view of capacity allocation and management. The main problems of reactive power and voltage are pointed out,and corresponding suggestions are presented. The work can be used for reference for optimization of reactive power and voltage control in the future.
