摘要：

为有效协调电网环境中的配置容量,针对不同模式分布式多电源开环接线法的可靠性展开研究。利用多电源滑模控制器协调分布式转矩间的电流比数值,进而计算电动机结构体的开环曲率,完成步进两相混合接线模式设计。重构配电网环境中的所有分布式节点,按照多级优化准则,计算开环馈线量的具体数值,完成双层配网规划接线模式设计。试验分析结果表明,该模式设计适应电网调度能力较强,与“一字”型开环接线法相比,应用步进两相混合接线模式后的电网容量超过100 TW·h,应用双层配网规划接线模式后的电网导容率达到90%,电网环境中的配置容量得到妥善协调,分布式多电源的应用可靠性出现明显上升趋势。

Abstract:

In order to coordinate the configuration capacity effectively in the power grid, the reliability of different modes of distributed multi-power source open-loop wiring is studied. The multi-power sliding mode controller is used to coordinate the current ratio between the distributed torques, and then the open-loop curvature of the motor structure is calculated. All the distributed nodes in the distribution network environment are reconstructed, and the specific value of the number of open-loop feeders is calculated according to the multi-stage optimization criteria, and the planning and connection mode design of the double-layer distribution network is completed. The experimental results show that the design of this mode has strong adaptability to power grid dispatching. Compared with the “one word” open-loop connection method, the grid capacity after applying the step-by-step two-phase hybrid connection mode is more than 100 TW·h. After the application of the double-layer distribution network planning and connection mode, the conductivity rate of the power grid can reach 90%, and the configuration capacity in the grid environment is properly coordinated, and the application reliability of distributed multi generation appears an obvious upward trend.

Key words: Distributed power source, motor curvature, distribution network reconfiguration
