摘要
为了提升静止无功补偿器传统控制模型的整体收敛水平,该文提出非线性负荷配电网静止无功补偿器的混沌解耦控制数学模型。以非线性负荷配电网运行所产生的数据作为依据,计算工作状态下静止无功补偿器参数,建立静止无功补偿器的状态方程;根据补偿器的受干扰情况,构建同步误差方程;在目标方程符合解耦条件的情况下,结合混沌控制理念,构建混沌解耦控制数学模型,并设置安全约束。实验结果表明,提出的数学控制模型在同一激励作用下,敏感度高、求解精度高,整体收敛水平也得到了提升,能够满足非线性负荷配电网的运行需求。
In order to improve the overall convergence level of the traditional control model of static VAR compensator,a chaos decoupling control mathematical model of static VAR compensator for nonlinear load distribution network is proposed.Based on the data generated by the operation of nonlinear load distribution network,the parameters of static VAR compensator under the working state are calculated,and the equation of state of static VAR compensator is established.Construct a synchronization error equation based on the interference situation of the compensator.Under the condition that the objective equation meets the decoupling conditions,combined with the concept of chaos control,a mathematical model for chaos decoupling control is constructed,and safety constraints are set.The experimental results show that the proposed mathematical control model has high sensitivity,high solving accuracy,and improved overall convergence level under the same excitation,which can meet the operational requirements of nonlinear load distribution networks.
