【摘要】 对江苏220 kV电压监控点电压、功率因数、电容器的投切情况等数据进行了统计分析,并采用无功平衡的方法分析了江苏省各高电压电网系统无功缺额情况。从管理和配置两方面对江苏220 kV电网的无功电压现状做出评估,指出220 kV电网无功电压存在的主要问题,并提出相应的解决方案及建议,可为无功电压的优化运行和管理提供参考。更多还原

【Abstract】 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.更多还原
