摘要
结合富春江发电厂机组振摆在线监测及保护系统改造工程,介绍了富春江发电厂改造方案的设计与实现。通过新旧在线监测系统及其软硬件配置的对比,深入地分析了原有在线监测系统的现状和存在的主要缺陷,阐述了新系统SJ-9000的性能特点。提出了具体设计方案及系统设备配置,对主要配备的SJ-90B装置和SJ-9000系统的特点进行了介绍。现场实践表明,该方案设计合理,运行稳定,对其他同等规模水电厂机组在线监测设计与实施具有借鉴意义。
Combining the reform project of hydraulic generator vibration and swing state monitoring and protection system in Fuchunjiang Power Plant to introduce the design and realization of reform scheme in Fuchunjiang Power Plant. By the comparison between the online monitoring system as well as the configuration of hardware and software of old and new generations, conducted deep analysis of the current situation and the main defects of the old online monitoring system and the main performance characteristic of SJ-9000 system. Proposed specific designing scheme and system configuration, and gave an introduction of the main configuration and characteristics to the SJ-90B installation and the S J-9000 system. Field practice showed that it is a reasonable scheme with stable operation, and it can provide references for the design and implementation of hydraulic generator vibration and swing state monitoring and protection system of the same-scale hydropower plant.
