凌津滩电厂通信传输系统改造方案分析

凌津滩电厂通信传输系统自1997年投运以来,未进行更新改造,仍一直使用制式和性能都已落后的陈旧设备,不仅日常维护和管理的难度大,而且给电厂数据业务、语音业务传输的安全性和稳定性带来了很大的安全隐患。本文主要介绍了凌津滩电厂通信传输系统现状和以后的发展模式,对凌津滩电厂通信传输系统可能采用的两种通信传输方式进行了探讨,研究了两种通信传输方式在电厂的运用。

五强溪水电厂通信系统综述

五强溪水电厂通信系统综述湖南省五强溪水力发电厂曾刚五强溪水电厂通信由调度及行政两大系统组成，共计有微波、载波、交换、光纤等通信方式，由于其采用生产区、生活区分离的“新厂新办”管理模式，故有电厂前方、后方、常德基地一厂三址之说，由此也决定了通信的复杂多...

Utilization of Data Communication according to the IEC61850 Standard for Nuclear Power Plant Electrical Equipment Testing

This paper deals with an integration of directly measured electrical parameters with data acquired by data communication from protections and terminals into an advanced monitoring system. Based on the periodic test, the authors of this paper present the possibility of an extended evaluation and more accurate analysis of transient and failure events. For periodical testing, as implemented during the commissioning of power plants in the Czech Republic, a monitoring system of electrical equipment has been used, to record the courses of important electrical parameters and thus, proving the proper functioning of complex technological systems in various operation modes. Data from monitoring system were used to prove the successful results of the test or as a base data for further analysis of failures. The monitoring system has proved itself as a very useful device also when recording unexpected failure events, the cause of which was very quickly and accurately detected by the follow-up analysis. Initially, only the voltage and current data from measuring transformers, analogue transducers and contact relays were used as input data for the monitoring system. After the implementation of new digital protection technology and controlling terminals with inner data recorder, the data from digital devices could be also utilized for the monitoring system.

雪夜抢修

"唐河到新庄方向光缆出现断芯故障!"2021年12月25日18点许,河南油田水电厂通信大队唐河通信站站长贺国平接到值班调度打来的电话。他立即放弃周末休假带领抢修小组快速赶往唐河通信站。到达唐河通信站后,大家立即用光缆测试仪,对故障点进行了定位排查,并很快确定故障点位于14.95公里的古城区域。站长贺国平一声令下。
