基于最小线损目标的长距离中压线路电压优化

Voltage Optimization of Long-Distance Medium-Voltage Line Based on Minimum Loss Goals

针对长距离中压线路的特点,基于最小线损目标,采用前推回代法和遍历搜索算法,建立了电压水平优化模型。通过初始化线路参数和负荷运行数据,理论计算线路无功补偿的最优位置、最优补偿容量,并综合考虑电压约束条件和经济性约束条件,最终得出最优优化方案。通过某典型长距离线路,验证了程序的正确性,有效指导长距离中压线路电压优化工程实践。

Considering the long-distance medium-voltage line characteristics,and based on the minimum line loss goals,using forward /backward substitution method and traversal search algorithm,a voltage level optimization model was established. By initializing the line parameters and load operational data,optimal reactive power compensation position,the optimal compensation capacity can be theoretically calculated. Eventually the optimal optimization program was formulated by considering voltage constraints and economic constraints. Finally,the correctness of the program was verified by a typical long-distance line,and effective guidance can be provided for the voltage optimization engineering practice of long-distance medium-voltage lines.
