    摘要:

    为提高缆系海底观测网的用能效率和运行可靠性,根据其物理架构特点设计了远程电能监控系统的总体结构,根据功能将该系统划分为数据采集、负载管理和网络分析三个子系统,说明了子系统的主要功能和相互关系.并研究了该系统的时间同步方案、负载供电优化策略和网络分析算法.通过理论分析,获得了分支单元节点电压向量的加权最小二乘状态估计公式,并基于电切换型分支单元的可控性,提出了海缆接地故障定位的新方法.研究内容可为未来国家海底观测网的设计和运行提供参考.

    Abstract:

    In order to increase the power efficiency and operating reliability of cabled seafloor observatory networks (CSONs), the overall structure of the remote power monitoring and control system (PMACS) is designed according to the CSONs’ physical characteristics. The PMACS is divided to three subsystems, which are the data collection subsystem, the load management subsystem, and the network analysis subsystem. The functions and relations of these subsystems are introduced and the time synchronization scheme, load power optimization, and network analysis algorithms are studied. Through theoretical analysis, the weighted least square state estimation of the branching unit voltages is generated and a novel method for the ground fault location of the CSONs’ submarine cable is presented based on the controllability of power switching branching units. The study can be a reference to the construction of national CSONs in future.
