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: |
In order to reliably monitor the secure and stable operation of distributed PV(PhotoVoltaic) system,the easy way is to establish a monitoring network and then apply the triangle deployment method to dispose the sensor nodes. But some target points may be left out due to the sensing limitation,aiming at which,the probabilistic perception deployment method is proposed to cover the omitted target points one by one. The two methods are compared by simulation and the simulative results show that,the omitted target points are covered one by one;and when the probabilistic constraint of node perception is bigger,the sensor nodes needed by the probabilistic perception deployment method are obviously less than those by the triangle deployment method. |
