摘要:
变电站的工作环境属于强磁环境,其中的弱电设备更容易受到外部雷达信号、GPRS信号和内部强电设备的电磁信号干扰,而传统变电站抗电磁干扰系统的误报警率高、信号滤波效果差,为此提出一种基于点云数据的变电站弱电设备抗干扰系统设计。抗干扰系统的硬件部分由STM32F103V型主控芯片、信号发射端子,信号接收端子,电源工作模块和点云数据滤波模块构成,详细介绍了主控芯片的电路结构和点云数据干扰滤波的原理,并给出基于点云数据的空间滤波网状结构,及弱电设备电磁干扰控制流程。实验数据的分析结果表明,提出基于点云数据的抗电磁干扰系统外部雷达信号滤波能力,与内部设备之间高频滤波能力,都优于传统的抗干扰系统,同时在电磁干扰误报警率控制方面的性能表现,也优于传统的DDC抗干扰控制系统和PLC抗干扰控制系统。
Abstract:
The working environment of substation belongs to strong magnetic environment, in which weak current equipment is more susceptible to interference from external radar signal, GPRS signal and internal strong current equipment, while the traditional anti-electromagnetic interference system of substation has high false alarm rate and poor signal filtering effect. Therefore, an anti-interference system design of weak current equipment of substation based on point cloud data is proposed. The hardware part of the anti-jamming system consists of STM32F103V main control chip, signal transmitting terminal, signal receiving terminal, power supply working module and point cloud data filtering module. The circuit structure of the main control chip and the principle of point cloud data interference filtering are introduced in detail. The spatial filtering network structure based on point cloud data and the electromagnetic interference control flow of weak current equipment are given. The analysis results of experimental data show that the filtering ability of external radar signal and high frequency filtering ability between internal equipment and point cloud data based anti-electromagnetic interference system are superior to traditional anti-jamming system. At the same time, the performance of error alarm rate control of electromagnetic interference is superior to traditional DDC anti-jamming control system and PLC anti-jamming control system.
