摘　　要：在新能源技术广泛应用的时代,微电网系统的稳定运行越来越重要,现阶段常规的电网故障检测和保护技术已经不能满足需求。因此,有必要根据微电网的运行特点,研究微电网故障分析和保护方案。研究发现微电网故障检测分为单一特征检测与多特征检测两种,单一特征故障检测虽然易于试验但容易出现误报,多特征故障检测虽然技术要求更高但更加准确。在微电网运行保护方面主要有基于本地信息和信息交流两种方案,基于本地信息的微电网保护方案虽然易于实现但不适用于微电网的智能化发展,希望本研究结果能够为提高微电网运行故障检测与保护水平提供理论参考。In the era of wide application of new energy technology, the stable operation of microgrid system is becoming more and more important. At present, the conventional power grid fault detection and protection technology can no longer meet the demand. Therefore, it is necessary to study the fault analysis and protection scheme of microgrid according to the operation characteristics of microgrid. The study found that microgrid fault detection is divided into two types: Single feature detection and multi-feature detection. Although single feature fault detection is easy to test but prone to false positives, multi-feature fault detection is more accurate although the technical requirements are higher. There are two main protection schemes based on local information and information exchange in microgrid operation protection. Although the protection scheme based on local information is easy to implement, it is not suitable for the intelligent development of microgrid. It is hoped that the results of this study can provide a theoretical reference for improving the fault detection and protection level of microgrid operation.
