长输管道的截断阀室是为了保证发生管道泄漏意外时最大限度的降低损失,减少周边环境污染,具有非常重要的作用。阀室的自动化控制和通信设备为管道运行的SCADA系统及在线检漏系统采集、上传各项数据,基于此原因阀室的供电保障显得十分重要。本文重点阐述风光互补发电系统的原理并分析其在安全可靠、降本高效、节能环保等方面的优势。 Long-distance pipeline cut-off valve chamber is to ensure that the accident occurs when the pipeline to minimize the loss to reduce the surrounding pollution, has a very important role. Valve chamber automation control and communication equipment for pipeline running SCADA system and online leak detection system to collect and upload the data, based on this reason the valve chamber power supply protection is very important. This article focuses on the principle of wind and solar power generation system and analyzes its advantages in safe, reliable, cost-effective, energy saving and environmental protection.
