高峰期电能传输中断的Petri网控制方案

Research on Petri Net Control Scheme for Power Transmission Interruption during the Peak Periods

传统的电能传输系统作为智能电网的基础核心主体,其运行的稳定性将直接影响智能电网的整体性能。特别是高峰供电阶段,电能传输系统必须具备较强的故障自愈能力。文章针对传统电能传输系统的基本结构及其监督控制系统,给出其Petri网形式化定义;通过对模型的分析,提出一套故障检测及定位方案;针对高峰用电期,提出一套优化的故障恢复方案,在保证系统具有较强自愈能力的同时,尽可能提高应急线路的利用率和系统故障的可恢复率。最后,通过一个实例对提出的方案进行说明并分析。

As an infrastructure, a traditional power transmission system （ TPTS） is the main body in a smart grid. Its stability af-fects the overall performance of smart grids. Especially,fault self - healing capability of TPTS is necessary and important for smart grids during the peak power transmission periods. TUs paper proposes the definitions of TPTmodel was analyzed and the schemes to detect fault and locate fault were presented. Moreover, a during the peak power transmission periods to improve the utilization rates of power emergency lines and system fault restoration rates.Finally, an example was given to illustrate the schemes.
