电力通信网检修模式下的风险预警机制

Abstract

电力通信网是保证电力系统安全稳定运行的通讯网络，是电网管理、调度自动化和管理现代化的基础。目前电力通信网正常运行模式下的风险管理、预警和评估已经逐步完善并广泛应用，但是针对N − X检修模式下的风险预警并未加以考虑。因此，本文首先简述了研究现状，接着提出应用需求与应用场景，然后详细描述了关于电力通信网N − X检修模式下的风险防范预警算法，包含检修处理、恢复两大模块，计算得到不可再检修的节点设备和链路。如果用户对风险节点设备或链路提出检修需求，即提示业务中断。最后在文末阐述了对未来的展望，分析了电力网和通信网的混合综合仿真及其相互的影响与风险。 Power telecommunication network is not only a communication network ensuring the safe and stable operation of power system, but also the basis of the power grid management, dispatching automation and management modernization. Currently the risk management, risk early-warning and risk assessment of power telecommunication network in normal operation mode have been gradually perfected and widely used. But risk early-warning in N − X maintenance mode hasn’t got the researchers’ concern. Therefore, the paper does some work in this aspect, mainly including: briefly introducing the research status, putting forward the application requirements and the application scenarios, detailing a risk prevention warning algorithm in N − X maintenance mode, analyzing the hybrid simulation of power grid and telecommunication network and their mutual impact and risk, and in the end, prospecting for future development. The algorithm contains two modules: maintenance and recovery. Firstly we get the node devices and links which can’t be maintained any more by calculation, and then if the user has demand for repairing risk node devices or links, system will raise service interruption alarm.
