中文摘要

随着变换器接口分布式电源在微电网中的普及,故障期间保护装置的有效动作成为技术挑战。由于半导体开关的限流特性,故障电流注入不足。本文提出了一种故障检测与清除控制策略,旨在利用传统保护手段解决变换器主导型微电网的故障清除问题。

English Abstract

The integration of converter-interfaced distributed generation in microgrids has raised several technical issues, including the successful operation of protective devices during faults. The protection issue is associated with the lack of large current injection during a fault, due to limits imposed by the semiconductor switches. This paper proposes a fault-detection and clearing control strategy m...

该研究直接关联阳光电源的构网型(Grid-forming)技术及微电网解决方案。在PowerTitan储能系统和组串式逆变器应用于弱电网或微电网场景时,由于逆变器过流能力有限,传统继电保护往往失效。本文提出的故障清除策略可增强阳光电源PCS产品在孤岛运行及微电网模式下的故障穿越与保护能力,提升系统可靠性。建议研发团队将该控制策略集成至iSolarCloud智能运维平台及PCS底层控制算法中,以优化微电网项目的故障响应性能,增强产品在复杂电网环境下的竞争力。
