Abstract：This paper analyzes the development and current situation of electric power dispatching data network， and points out the problems that electric power dispatching data network needs to overcome. The construction of the second plane of power dispatching data network helps to solve the defects of single routing plane network， and can significantly improve the reliability and service guarantee ability of business system. MSTP technology is also briefly analyzed， which makes full use of SDH technology. After some column transformation， it can adapt to more types of business applications and support various types of data transmission. This is a significant improvement in the speed of service provision， improving the scalability of the network， and effectively reducing the operation and maintenance costs of the network. Based on MSTP technology， the second network of dispatching data network is established. The combination of the two advantages can improve the reliability， security and efficiency of dispatching data network to a greater extent.

Key words：MSTP technology; SDH technology; dispatching data network; second platform; dual platform network

电力调度数据网主要是用来传输电网自动化信息、继电保护和安全自动装置控制信息、以及调度指挥指令等等，同时也是一种电力生产调度控制大区服务的专用的数据网络，调度数据网的存在实现了电力的实施控制和在线生产交易等多种电力业务，另外它也是智能化电站建设的技术支撑。因此，建立一个安全、可靠、高效、经济的调度数据网十分重要，它不仅能够起到保护系统安全的作用，还能确保不同业务系统之间能够有效隔离，进而有效提高业务保障能力，网络可靠性也得到大大提高，对加强智能电网调度系统建设有着十分重要的意义。目前的调度数……
