分布式配电自动化系统的研究

Research of Automation System for Distributing Substation

论述了城市配电网络的发展和配电网络自动化的进展———由集中式控制向分散控制的转变,介绍了当前典型网络系统的结构和功能,论述了分布式控制底层基于现场总线网络的组建和网络中智能节点的硬件电路设计和软件流程设计,并分析了本系统在配电网中应用对组建成本,难度的降低,对配电系统平时监视控制性能的提高以及对故障时的动作方式的改进,提高了供电质量。并且讨论了本系统的优点和不足,提出进一步改进的建议。

Improvement of automation of distribution station ——from centralization to distribution is discussed in this paper. Construction and function of typical distribution networks in use in developed areas are introduced. Controller area network construction, hardware and software design of field bus intelligent node and its behavior when disturbance occurs are described. In contrast with traditional method such as SCADA and etc, more quality of power supply has been achieved by less fee and more efficiency supported by more advanced communication technology. At last, advantage and disadvantage of this system is analyzed, proposition for improvement is given also.
