摘要
超高层建筑配电网的两阶段优化,阶段Ⅰ依据建筑配电变压器标准规格,以负荷饱和度、反峰谷差率和日负荷率为评估指标,优化超高层建筑的供电区划分;阶段Ⅱ以最小化变压器和线路投资成本、系统年网损为目标,优化建筑内变压器和中低压线路的配置方案;以某实际超高层建筑为例进行对比分析,结果表明所提超高层建筑配电网两阶段优化方法不仅能减少设备的初始投资,还可进一步提升超高层建筑配电网运行的稳定性和经济性.
Abstract
The two-stage optimization of the distribution network of super high-rise buildings.According to the standard specifications of building distribution transformers,stage I optimizes the division of power supply areas of super high-rise buildings with load saturation,inverse peak-valley difference rate and daily load rate as evaluation indicators.Stage II optimizes the configuration scheme of transformers and medium and low voltage lines in buildings with the goal of minimizing the investment cost of transformers and lines and the annual network loss of the system.Taking an actual super high-rise building as an example for comparative analysis,the results show that the proposed two-stage optimization method of super high-rise building distribution network can not only reduce the initial investment of equipment,but also further improve the stability and economy of super high-rise building distribution network operation.
