摘要
提出一种基于 SCADA的综合控制变压器分接头和并联电容器组的模糊线性规划方法 ,进行配电站电压无功实时监控。通过推导配电站二次母线电压 V2 的方程 ,建立各物理量的隶属函数及模糊目标函数 ;运用 9域图和线性规划算法 ,得到使 V2 偏差最小的最优调控策略。
A fuzzy linear programming method based on SCADA and used for the combined control of load tap changer and switching over shunt capacitors bank is proposed, to solve the real time vol/var control problem in a distribution substation. With developing the equation of the secondary bus voltage(V 2), establishing the membership functions of variables and the fuzzy object function, making using of nine field figure and linear programming method, the optimal operate policy is obtained to limit the deviation of V 2 to the minimal. This algorithm shows well in practical application.
