摘要

在安大略省,将农场沼气发电与农村配电馈线连接的经验揭示了电气保护方面的一些挑战。沼气项目规模小(<500kW),同步,以农场为基础,寻找一种经济实惠的保护解决方案,只使用低压设备。公用事业馈线通常在8.3kV和12.5kV电压水平,可能涉及较长的长度,并且由于单相分支的存在而存在明显的不平衡。主要的挑战来自两个要求。

Protection challenges facing Distributed Generation on rural feeders
Experience with connecting farm biogas generation to rural distribution feeders in Ontario has revealed several challenges with electrical protection. The biogas projects are small (<500kW), synchronous, farm-based, and looking for an affordable protection solution involving the use of only low-voltage equipments. The utility feeders are generally at the 8.3kV and 12.5kV voltage levels, can involve long lengths and contain significant imbalance due to the presence of single-phase laterals. The main challenges arise from two requirements.
