电压的问题关系到系统运行的稳定性及用户的正常使用,它和无功功率的分布有很重要的关系。无功功率会随线路流向负荷端并产生电压的损耗。变电站无功控制是指通过控制并联电容器组投入切除和调节主变分接头开关升降来达到电压水平稳定和无功功率平衡的目的。通过研究变电站V-Q控制的数学模型,分析其控制特性,掌握电压无功控制规律对变电站控制电压水平和无功平衡有着一定的参考价值。
The voltage problem is related to the stability of the system operation and the normal use of the user. It has a very important relationship with the distribution of reactive power. Reactive power flows with the line to the load and voltage loss. Substation reactive control refers to the control of parallel capacitor bank put into the cut and adjust the main transformer tap changer to achieve the stability of the voltage level and reactive power balance purposes. By studying the mathematical model of substation V-Q control, analyzing its control characteristics and mastering the law of voltage and reactive power, it has certain reference value for substation control voltage level and reactive power balance.
