永州南500kV变电站无功补偿装置的选择及配置

根据永州南电网发展现状,该地急需动态无功补偿装置进行无功和电压平衡。本文通过对多种无功补偿装置的比较,在永州南500 kV变电站选用TCR+FC型SVC,并对SVC各支路配置进行分析计算,得出配置参数。该套SVC将作为湖南电网仅有的一套动态无功补偿装置,对于湘南电网的电压稳定发挥重要作用。

Selection and configuration of reactive compensation equipment for 500 kV substation in south of Yongzhou

According to the present situation of power grid in south of Yongzhou,a dynamic reactive compensation equipment is needed urgently to maintain the balance of reactive power and voltage.According to the comparison of multiform reactive power compensators,the TCR combined with FC and filter SVC are selected for 500 kV substation in south Yongzhou,and the corresponding configuration parameters are obtained by calculating and analysis of each branch of SVC.The SVC will be taken as the only set of dynamic reactive power compensator of Hunan power network,and play an important role for voltage stabilization of power grid in south Hunan.
