摘要
传统系统缺少电网信号监控风险预警体系,导致信号监控风险预警效果较差,为了解决该问题,提出了基于调控一体化电网信号监控风险预警系统。根据系统总体架构,对电网信号进行监控,构建以太冗余双环网,为系统提供充足电力,安装信息采集器,通过风险信息采集电路获取相关信息,设计监控器,选择型号为LM358的阻值放大器,根据电路阻值转换原理,对电网信号进行实时监控,进而改善噪声干扰问题。根据电网信息监控风险预警体系,设计软件工作流程,实现对电网信号监控风险预警。通过实验对比结果可知,该系统最高预警效果可达到91%,大大降低电网事故发生概率。
The traditional system lacks the early warning system of power network signal monitoring risk,which leads to the poor effect of early warning of signal monitoring risk. According to the system architecture,the network signal is monitored,the Ethernet redundant double-loop network is constructed to provide sufficient power for the system,the information collector is installed,the relevant information is obtained through the risk information collection circuit,the monitor is designed,and the resistance amplifier of LM358 is selected. According to the circuit resistance conversion principle,the network signal is obtained. Real time monitoring is carried out to improve noise interference. According to the risk early warning system of power network information monitoring,the software workflow is designed to realize the risk early warning of power network signal monitoring. The experimental results show that the highest early warning effect of the system can reach 91%,greatly reducing the probability of power grid accidents.
