智能变电站录波方案的探索与实践

Research and practice of wave recording scheme for smart substation

结合目前智能变电站的工程实践,研究提出智能变电站的录波方案。在智能变电站建设中,仍需要配置独立的录波装置,录波装置应整合网络记录分析等功能,实现三态录波。录波装置应适应不同的变电站过程层组网结构,注意数据同步性、数据真实性等问题。录波装置记录合并单元的输出更可行,记录可能非同步的原始报文值并进行同步,可选择展现同步或非同步值,甚至原始报文。录波装置要保证接入的GOOSE报文冗余可靠,并且保证足够的GOOSE报文分辨率。要开展录波数据的深度利用和拓展应用,充分结合其他数据,构建统一数据信息平台,实现站端和调度端的状态估计、三态数据分析等高级应用。

The wave recording scheme for smart substation is presented combined wlm me practice. Independent wave recorder is still needed,and it should integrate the functions of network recording and analysis,realize the tri-state recording,be suitable for different network structures of station process level, and pay attentions to data synchronization and data authenticity. It is more practical to record the output of merging units. The asynchronous original message should be recorded and synchronized,both being optionally shown. The received GOOSE message should be redundant and reliable,with enough resolution. Combined with other data,deep and expanded applications of recorded data should be developed on unified information platform to realize the state estimation and tri-state data analysis in both substation and dispatch center.
