摘要
近年来,风力/光伏发电技术快速发展,监测系统变得愈加复杂,影响发电效率的气象数据的分辨率、延时等特性对电网监测提出了更高的要求。文章分析了传统监测系统存在的典型问题,结合4G无线通信技术,设计了一种高分辨率、低延时的并发监测系统,将延时由数百毫秒降低至数十毫秒,分辨率提升到传统系统的5倍,有助于提高发电场的资源利用率,保证数据质量和安全生产。
In recent years,the power generation technology of wind or solar energy has been developed rapidly,and the monitoring system is more complicated.The power grid monitoring has urgent requirement for high-resolution and low-latency weather data,which affect the power generation efficiency.In this paper,the problems existing in the traditional monitoring system are studied.Based on the 4G wireless communication technology,a high-resolution,low-latency concurrent monitoring system is designed.The system reduces the delay to tens of milliseconds,and the resolution is five times that of the traditional system.It helps to improve the resource utilization rate of the power station,and ensure the data quality and production safety.
