摘要
本文针对配电网的特点,以配电网的网损和负序电流为目标建立配电网无功优化运行控制的数学模型,并使用简化梯度法对其求解,得到配电网各补偿节点配电网无功优化运行控制的指标。经算例验证,本文提出的配电网无功优化运行控制方案,能有效地提高配电网的电压水平,兼顾网损最小和负序电流最小。
According to the characteristics of distribution network, in this paper, it is establishing the mathematical model of automatic voltage and reactive power operational control, to the loss and negative sequence current distribution network for the goal and use the simplified gradient method for solving, get the target of automatic voltage and reactive power operational control at every compensation node in distribution networks. By the numerical example, this paper, the program of voltage and reactive power operational control in distribution networks, can effectively improve voltage level in the distribution networks, taking into account the minimum loss and minimum negative sequence current.
