Redundant configuration protection system based on layered Markov model

为了实现对电量配置环境的合理保护,设计基于分层马尔可夫模型的冗余配置保护系统。利用完全双重化配置电路,提供交流电子滤波器与CAN总线稳流器所需的匹配电流,完成冗余配置保护系统的硬件执行环境搭建。在此基础上,建立分层马尔可夫决策链,分别从动、静态保护条件两个角度着手,计算冗余电量配置的准则函数结果,实现冗余配置保护系统的软件执行环境搭建,再结合各级硬件设备结构,完成系统设计。实现结果表明,与MEMS惯性处理手段相比,在分层马尔可夫模型作用下,实际电流谐波曲线能够更好地贴合理想波动曲线,可在保护高压电网配置环境的同时,避免冗余电量对应用电网造成击穿影响。

In order to realize the reasonable protection of power configuration environment,a redundant configuration protection system based on hierarchical Markov model is designed.The complete dual configuration circuit is used to provide the matching current required by AC electronic filter and CAN bus regulator,and the hardware execution environment of redundant configuration protection system is built.On this basis,a hierarchical Markov decision chain is established to calculate the criterion function results of redundant power configuration from the perspectives of driven and static protection conditions,so as to build the software execution environment of redundant configuration protection system,and then complete the system design in combination with the structure of hardware equipment at all levels.The results show that compared with MEMS inertial processing means,under the action of hierarchical Markov model,the actual current harmonic curve can better fit the ideal fluctuation curve,which can protect the configuration environment of high⁃voltage power grid and avoid the breakdown impact of redundant power on the application power grid.
