CERTS Microgrid Test Bed Demonstration Data

The objective of the CERTS Microgrid Test Bed Demonstration, which was hosted by American Electric Power, was to enhance the ease of integrating small energy sources into a microgrid. The project accomplished this objective by developing and demonstrating three advanced techniques, collectively referred to as the CERTS Microgrid concept, that significantly reduce the level of custom field engineering needed to operate microgrids consisting of small generating sources. The techniques comprising the CERTS Microgrid concept are: (1) a method for effecting automatic and seamless transitions between grid-connected and islanded modes of operation; (2) an approach to electrical protection within the microgrid that does not depend on high fault currents; and (3) a method for microgrid control that achieves voltage and frequency stability under islanded conditions without requiring high-speed communications. The test data is grouped by each phase of the project. Each phase of the project has an associated .xls file that contains a log of the test set-up, comments and the folder where the data is stored. The waveform data for each test is stored in a .parquet file. These files can be easily imported using many standard programming languages including MATLAB and using the pandas library in Python. The columns in each file are - Datetime_ns: The datetime stamp of the measurement in nanoseconds. - EventTime_s: The timestamp trigger of the recorded event in seconds. The meter typically records 0.25 seconds before the event and up to 5 seconds after the event trigger - Va: The instantaneous voltage measured on Phase A as a % of the nominal voltage - Vb: The instantaneous voltage measured on Phase B as a % of the nominal voltage - Vc: The instantaneous voltage measured on Phase C as a % of the nominal voltage - Ia: The instantaneous current though Phase A in amps - Ib: The instantaneous current though Phase B in amps - Ic: The instantaneous current though Phase C in amps The data 'Datetime_ns' is timezone agnostic and can be converted to human-readable format for cross-referencing with the test logs using the pandas function pandas.Timestamp.

由美国电力公司（American Electric Power）主办的CERTS微电网测试平台演示项目，其目标为提升小型能源接入微电网（microgrid）的便捷性。本项目通过开发并演示三项统称为CERTS微电网理念的先进技术，达成了上述目标——这些技术可显著降低由小型发电单元构成的微电网在运行时所需的定制化现场工程工作量。

构成CERTS微电网理念的三项技术分别为：
1. 实现并网与孤岛运行模式间自动平滑切换的方法；
2. 无需依赖高故障电流的微电网内部电力保护方案；
3. 无需高速通信即可在孤岛工况下实现电压与频率稳定的微电网控制方法。

本次项目的测试数据按各实施阶段进行分组。每个项目阶段对应一份.xls文件，其中包含测试配置日志、备注信息以及数据存储文件夹的路径。各项测试的波形数据存储于.parquet文件中，此类文件可通过包括MATLAB在内的多种标准编程语言，以及Python的pandas库实现快速导入。

各文件包含的字段说明如下：
- Datetime_ns：以纳秒为单位的测量时间戳，其时区属性无关，可通过pandas.Timestamp函数转换为人类可读格式，以便与测试日志进行交叉比对。
- EventTime_s：以秒为单位的记录事件触发时间戳，该测量仪表通常会采集事件触发前0.25秒至触发后5秒的波形数据。
- Va：A相测得的瞬时电压，以额定电压的百分比形式表示。
- Vb：B相测得的瞬时电压，以额定电压的百分比形式表示。
- Vc：C相测得的瞬时电压，以额定电压的百分比形式表示。
- Ia：A相回路的瞬时电流，单位为安培。
- Ib：B相回路的瞬时电流，单位为安培。
- Ic：C相回路的瞬时电流，单位为安培。
