Realistic Australian Medium Voltage Feeder with Associated Low Voltage Feeders

This is a realistic data set based on a real-world power distributed network. Though the data set is constructed carefully, and sanity tests have been performed for both the topology and the impedance values in the data set, there was no further validation performed as part of this work. The data represents a single medium voltage feeder and 33 associated low voltage feeders in OpenDSS format. \n\nThe medium voltage feeder data originates from suburban part of Australia. It is an 11 kV feeder with a variety of residential LV feeders underneath, with an operational voltage of 400/230 V +/-10%. \n\nAn OpenDSS model containing this data has been constructed. To make the data realistic for the Australian context, we have also made a number of additions to the data set based on engineering rules of thumb and best practice.\n\nThe data were obtained and cleaned in order to support a research project in 2025 on the calculation of dynamic operating envelopes.\nLineage: The data is being provided by GridQube. \n\nThe following information has been obtained by tracing the data from the GIS:\n• Operational topology, which is radial\n• Construction codes or cable properties\n• Line lengths\n• Customer service points\n• Switch locations\n• Transformers and their electrical properties\n\n\nTo make the data realistic for the Australian context, we have also made a number of additions to the data set based on engineering rules of thumb and best practice:\n• Added neutral grounding points at the Wye side of the MV/LV transformers\n• Added neutral grounding points at the customer sides\n• Mapped line/cable information to approximate impedances through the modified Carson’s equations\n• Customers in all of the networks have been assigned a single-phase connection phase-to-neutral, with connections assigned mod 3 to the phase wires, i.e. a b c a b c …\n• Open and closed switches have been kept in the model\n

本数据集为基于真实电力分布式网络的写实型数据集。尽管本数据集经过精心构建，并已针对拓扑结构与阻抗值完成合理性校验，但本研究未对其开展额外验证工作。该数据集以OpenDSS格式存储，包含1条中压馈线及配套的33条低压馈线。

其中中压馈线数据源自澳大利亚郊区，为一条11 kV馈线，配套多条住宅类低压馈线，运行电压为400/230 V ±10%。

已基于该数据集构建OpenDSS模型。为适配澳大利亚本地场景以增强数据真实性，研究团队依据工程经验法则与行业最佳实践，对数据集进行了多项补充完善。

本数据集采集并清洗自2025年一项关于动态运行边界计算的研究项目。数据溯源：本数据集由GridQube提供。

以下信息均通过溯源地理信息系统（GIS）中的数据得到：
• 径向运行拓扑结构
• 线缆敷设规范与电缆参数
• 线路长度
• 用户服务点
• 开关位置
• 变压器及其电气参数

为进一步适配澳大利亚本地场景以提升数据写实性，研究团队依据工程经验法则与行业最佳实践，额外对数据集开展了如下补充：
• 在中低压变压器的星形侧增设中性点接地点
• 在用户侧增设中性点接地点
• 通过修正版卡森方程（Carson’s equations）将线路/线缆信息映射为近似阻抗值
• 为所有网络中的用户分配单相相-中性线连接，并按mod 3规则分配相序（即a→b→c→a→b→c……）
• 模型中保留了分合闸状态的开关设备
