Abstract:

微网技术作为一种普及新能源的新兴方式，具备灵活的运行方式、可靠的供电能力和优质的电能质量，是未来电力工业发展的重要方向，但是传统的继电保护对微网的保护效果并不明显，需要研究新的保护方案。本文在分析微网特性的基础上，提出了微网保护需要考虑的问题；接着比较了微网保护与传统配网保护以及有源配电网保护的异同，在此基础上提出了微网保护配置的特点与难点；然后从含微网的配网保护以及微网系统自身保护研究两个方面对国内外微网保护研究现状和成果进行了总结。最后，就未来微网保护给出了一些建议。
Micro network technology as a new way to popularize new energy, with flexible operation mode, reliable power supply capacity and quality of power quality, is an important direction of the future development of the power industry. But the protective effect of traditional relay protection is not obvious, and the new protection scheme is needed. The paper put forwards the micro grid protection needs to be considered in the analysis based on micro network, and then compared the micro network protection and the protection of traditional distribution network and active distribution network protection of the similarities and differences, based on proposed micro network protection configuration characteristic and the difficulty. And then from containing micro grid distribution network protection and micro grid system, its protection of two aspects of domestic and foreign micro grid protection status and achievements of the research on are summarized. Finally, some suggestions are given for the future micro grid protection.
