摘要
电厂远程诊断系统诊断功能的实现需建立在大量实时数据的基础上。如何从相对封闭的传统火电领域获取相关发电数据并将数据传输至诊断平台都是亟待解决的关键问题。本文从某大型百万千瓦机组电厂的实际条件与需求出发,研究了数据采集、数据处理、数据缓存、数据发送、数据异常处理机制等方法,给出了系统的实现拓扑结构,形成了一套完整的数据采集和传输方案,可实现与电厂SIS系统的对接,实现机组配套设备数据的接入,实现实时数据和离线数据的安全传输。该设计方案有广泛的适用性,尤其是对需要改造升级引进远程诊断系统的电厂有较强的借鉴性及参考价值。
The realization of the remote diagnosis system of power plant needs to be based on large sets of real-time data.How to obtain the relevant power generation data from the relatively closed traditional thermal power field andtransmit the data to the diagnosis platform are all key problems to be solved.Based on the actual conditions and requirements of a million kilowatt power plant,this paper studies the methods of data acquisition,data processing,data caching,data transmission,data anomaly handling mechanism,and gives the implementation topology of the system,forming a complete data acquisition and transmission scheme.The scheme can interface with the SIS system and the auxiliary equipment,assure security transmission of real-time data and offline data,which is widely applicable,especially valuable for power plants that need to be upgraded.
