【摘要】：评估馈线供电能力是保障馈线可靠运行的重要手段。文中提出了一种基于路径描述的馈线分区N-1可装容量计算方法。首先,将同一电压等级配电网以自动/手动开关装置为边界划分馈线分区,视为负荷节点;采用所有负荷节点及其所有可能供电路径的集合描述配电网拓扑结构。随后,以路径状态为变量,建立了馈线N-1安全校验的0-1线性规划模型。针对电网营销部门的实际数据需求,以路径状态和馈线分区可装容量为变量,进一步建立了用于馈线分区N-1可装容量计算的混合整数线性规划模型。最后,以某省会城市实际运行的某一10 k V馈线组为例,验证了所提算法的实用性和有效性。
[Abstract]:Evaluation of feeder power supply capacity is an important means to ensure reliable operation of feeder line. In this paper, a method for calculating N-1 loadable capacity of feeder partition based on path description is proposed. First, the distribution network of the same voltage level is divided into feeder areas with the boundary of automatic / manual switching devices as load nodes, and the topological structure of distribution network is described by the set of all load nodes and all possible power supply paths. Then, a 0-1 linear programming model for the safety check of feed line N-1 is established with path state as variable. According to the actual data demand of power network marketing department, a hybrid integer linear programming model for the calculation of N ~ (-1) loadable capacity of feed area is further established, which takes path state and feeder partition's loadable capacity as variables. Finally, the practicability and validity of the proposed algorithm are verified by taking a 10kV feeder set actually running in a provincial capital city as an example.
