摘要
在配电网严格数学模型的基础上,针对配电网拓扑分析、潮流计算及故障恢复等不同应用,建立相应的简化模型,剔除冗余信息,提高处理效率;对于失电区内的分布式电源在故障恢复过程中采用分层运行方式,减少停电范围,充分利用了分布式电源的发电能力;提出了多类型的故障恢复算法,即根据失电区域所在馈线组的网络结构,分别采用合适的算法,以减少不必要的搜索,大大提高了算法的计算速度。通过一个实际配电系统仿真表明,提出的配电网故障恢复方案可以实现非故障失电区的快速恢复供电。
For different applications, the paper establishes the appropriate simplified models based on the rigorous model of the distribution network which can eliminate the redundant information and improve processing the efficiency. The hierarchical islanding in the power failure area can reduce the range of power failure and make full use of the gen- erating capacity of distributed power. Multiple types of service restoration algorithms which adopt the appropriate algo- rithm for different network structures are proposed to reduce the unnecessary searches and improve the computing speed greatly. A practical distribution system simulation shows that the distribution network service restoration algorithm can restore the power of the power failure area quickly.
