【摘要】：对分布式光伏发电进行可靠监控,可保障其安全稳定运行。首先构建了分布式光伏发电系统监控网络,然后采用三角形部署法进行传感器节点部署,该方法简单易行,但在实际运行中会因为感知受限而遗漏部分目标点;为了解决监控遗漏问题,提出概率感知部署法对目标点进行逐个覆盖。对2种方法进行仿真对比,结果表明:概率感知部署法可对三角形部署法遗漏的目标点进行逐个覆盖;当节点感知概率约束值较大时,概率感知部署法所需传感器节点明显少于三角形部署法。
[Abstract]:Reliable monitoring of distributed photovoltaic power generation can ensure its safe and stable operation. Firstly, the monitoring network of distributed photovoltaic power generation system is constructed, and then the triangular deployment method is used to deploy sensor nodes. This method is simple and feasible, but it will miss some target points because of the limitation of perception in practice. In order to solve the problem of monitoring omission, the probabilistic perceptual deployment method is proposed to cover the target point one by one, and the two methods are simulated and compared. The results show that the probabilistic perceptual deployment method can cover the missing target points one by one. When the value of perceived probabilistic constraint is large, the sensor nodes required by probabilistic deployment are obviously less than that of triangular deployment.
