“大运行”背景下，广域分布式地县调控一体化系统能很好地适应地县级智能电网调度自动化建设的需要，但是数据采集、应用、计算机节点的广域分布必然带来故障点增多及运行可靠性降低和数据不一致的风险，设计分区解并列机制的目的就是解决各类网络故障下地县运行的各种问题。文中简要介绍了广域分布式地县调控一体化系统，重点介绍了分区解并列机制的关键技术及实现原理。现场实际运行情况表明，分区解并列机制能有效保障广域分布式地县调控一体化系统的安全、稳定运行。

In the background of“large operation",the wide area distributed prefecture-county integrated dispatching automation system can greatly conform to the construction need of prefecture-county smart grid dispatching automation.But the wide area distribution of data acquisition,various applications and the computer nodes is bound to bring about the risks of more faults and lower reliability as well as the data inconsistency caused by the network faults.The design of network division/recovery mechanism is intended to solve the problems of the prefecture-county dispatching operation due to the network faults.The wide area distributed prefecture-county integrated dispatching automation system is briefly described,with emphasis on the key technology and principles of the network division/recovery mechanism.It is proved that the communication network division/recovery mechanism can effectively safeguard the operation of the wide area distributed prefecture-county integrated dispatching automation system as can be seen from field proj ects in operation. <br> This work is supported by National High Technology Research and Development Program of China (863 Program) (No.2011AA05A118).
