总线式绝缘在线监测系统的同步采样控制

Synchronous Sampling Control of Bus Model On-Line Insulation Monitoring System of Equipments

为便于监测种类繁多、分布分散的变电站高压设备绝缘,阐述了应用现场总线技术组建的总线式电站设备绝缘在线监测系统的结构,提出了多下位机同步采样控制新方法。基于该方法开发的一套电站设备绝缘在线监测系统在实际工程的应用实践验证了该方法和设计方案的可行性。

High-voltage electrical equipment is distributed everywhere in substation. So the bus model on-line insulation monitoring system is adapted. In this paper, the principle of synchronous sampling is put forward. Based on these techniques, a bus model on-line insulation monitoring system is development, and it has already been used in the substation. The method and the design prove to be efficient through test of practical project.
