10 kV线路无功优化补偿系统研究

在10kV线路中安装无功补偿装置可有效改善电压质量、提高运行的经济性.但原有的无功补偿模式存在不足之处,为了进一步降低网损,提高用户电压质量,开发了10kV线路无功优化补偿系统,先运用非节点无功优化算法确定10kV线路无功补偿位置及补偿容量,在此基础上研制并安装了集无功自动补偿、电容器保护于一体的智能型户外无功补偿装置,经过试运行分析,可以有效提高电压质量水平,进而提高了运行的经济性.

Study on Reactive Power Optimizing Compensation System of 10 kV Line

Aiming at improving the quality of the voltage and promoting economical operation,Reactive Power Com-pensation Equipment is installed in 10 kV Line.But there is the original deficiency of reactive Power Compensation model.In order to reduce network decrease and raise user's voltage quality,the Reactive Power Compensation system of 10 kV Line is designed.Firstly,Reactive Power Compensation position and compensation capacity are determined with non-nodal reactive compensatory optimization algorithm.Then the intelligent outdoor reactive rower compensation equipment,which is an integration of reactive power automatic compensation and the capacitor protection,is developed and installed.Trial operation shows that this reactive power optimization compensation system can improve the voltage quality effectively and promote the economical operation of power systems.
