本文提出了基於換流器與同步發電機的分散式發電系統之應用混沌產生器被動式孤島偵測法。可惜的是，當實/虛功率不匹配率接近於零時，大多數被動式孤島偵測法都無法偵測到孤島現象。
本文介紹了一種應用混沌產生器於被動式孤島偵測法，該方法能夠偵測出實/虛功率不匹配接近零的孤島狀態，利用責任分界點電壓和頻率偏差量作為混沌產生器的輸入訊號。混沌產生器的主要優點是其混沌運動態與發散運動態之間差異明顯。在混合式分散發電系統情況下，考慮導致系統電壓和頻率暫時偏差的非孤島現象，這些事件包括不同類型的故障，例如：三相接地故障、三相短路故障。此外，對於孤島現象，通過接近零的功率不匹配和基於IEEE Std. 1547標準，對提出的偵測法能力進行了驗證。也透由硬體實驗分別以單台換流器與多台換流器，採用IEEE Std. 929-2000標準反孤島效應保護測試，成功實現準確且快速的孤島偵測。

This paper proposes a passive-based anti-islanding detection method for both inverter and synchronous machine-based distributed generations.
Unfortunately, when the active/reactive power mismatch is near to zero, the majority of passive anti-islanding methods can't detect the islanding condition.
This paper introduces a islanding detection method based on the chaos theory that can detect the islanding condition with near-zero power mismatch. The method uses the modified voltage and frequency of the point of common coupling link as an input signal of chaos generators. The obvious change between chaotic and divergent motions in the chaos generators is its main advantage. The non-islanding transient events, which can cause a significant deviation in the voltage-based and frequency-based input signal of detector, are considered in simulations for hybrid distributed generations. These events include different types of faults, like the three phase to ground (LLLG) and three phases (LLL). Further, for islanding events, the capability of the proposed islanding detection method is verified by near-to-zero power mismatch and IEEE Std. 1547-based. Through the hardware experiments, the anti-islanding effect protection test of IEEE Std. 929-2000 is adopted for a single converter and multiple converters respectively, the accurate and fast islanding detection is successful.
