在输电网中引进网络重构的概念,提出可以通过输电网络重构发挥输电网自身潜力而实现提高系统可靠性、降低短路电流、优化系统潮流、消除输电阻塞、释放发电能力、减少用户停电损失等目的。在运行实践中输电网络重构有多种实现方法,阐述了上海电网徐行/黄渡分区进行输电网络重构的实践及有效缓解500kV外顾双线潮流从而解决限制上海最高用电需求能力的瓶颈问题,为2007年上海电网迎峰度夏顺利进行提供了保障。
Introduced the concept of network reconfiguration in transmission network and put forward that it can realize the potential of transmission grid through the reconstruction of transmission network to improve the system reliability, reduce the short circuit current, optimize the system power flow, eliminate the transmission congestion, release the generating capacity and reduce the power outage of users Other purposes. There are many ways to reconstruct transmission network in operation practice. The practice of transmission network reconfiguration in Xuhang / Huangdu sub-area of Shanghai Power Grid and the bottleneck to effectively limit the power consumption of 500kV external power line and double-line in Shanghai to solve the problem of maximum power demand in Shanghai Issue, for the summer of 2007 in Shanghai peak summer peak provides a guarantee.
