摘要

介绍了变电站IED数据集成的概念,这些数据主要来自数字保护继电器和数字故障记录仪。现代变电站配备了不同类型的简易爆炸装置。dfr传统上用于从电力系统中可能需要分析的各种事件和干扰中捕获数据。大多数现代ied(简易爆炸装置),如数字继电器、电能质量计和事件序列记录仪,都可以提供与dfr非常相似的数据记录功能。在最近的一些变电站设计中,DFR功能被dpr提供的等效功能所取代。也有使用dfr和dpr并将其配置为记录相同事件的情况。在这种情况下,dpr的记录被用作事件分析的冗余源。本文论述了变电站数据集成的主要要求:通信与自动化IED数据检索、统一事件数据文件格式、验证事件数据内容、正确处理系统配置参数。通过扩展现有的DFR数据集成和分析系统,并通过引入来自不同变电站ied的数据,讨论了使用所提出概念的变电站数据集成示例。利用数字模拟器对多个IED类型的示例概念进行了评估

Integration of Substation Data
The paper introduces a concept for integration of substation IED data, primarily coming from digital protective relays (DPRs) and digital fault recorders (DFRs). Modern substations are equipped with different types of IEDs. DFRs are traditionally used to capture data from various events and disturbances in the power system that may need to be analyzed. Most of the modern IEDs such as digital relays, power quality meters, and sequence of event recorders can offer data recording function that is quite similar to that of DFRs. In some recent substation designs there are cases where DFR function is replaced by an equivalent function provided by DPRs. There are also cases when both DFRs and DPRs are used and configured to record the same events. In this case records from DPRs are used as a redundant source for event analysis. The paper addresses main requirements for integration of substation data: communication and automated IED data retrieval, unifying event data file formats, verification of event data content, and proper handling of the system configuration parameters. Examples of substation data integration using the proposed concept are discussed through expansion of an existing DFR data integration and analysis system and through introduction of data coming from different substation IEDs. Digital simulator was used to evaluate the concept in the example with multiple IED types
