| 摘 要： | 在变电站电压无功功率综合控制系统(VQC)中,使用传统九区域图法存在设备频繁调节或振荡调节缺陷,因此,提出了在调节变电站分接头或投切无功补偿设备之前,能准确预测设备动作之后的补偿侧母线电压变化值和主变压器各侧的无功潮流变化值的算法.使用该算法,不仅可以提高控制准确性,而且可以提高控制可靠性,避免设备频繁调节或振荡调节.

| Abstract: | In substation voltage and reactive power integrated control system（VQC）,using traditional nine regional methods,there would be defects in oscillation adjustment or frequency adjustment.So a new algorithm is proposed,which can accurately forecast the bus voltage and reactive power flow in value,before switching transformer taps or adjusting reactive compensation equipment.Using this algorithm,it not only can improve the control accuracy but also can improve control reliability and avoid frequent equipment adjustment or oscillation adjustment. |
