摘　　要：针对分布式并网发电系统中遇到的孤岛效应问题,首先介绍了传统的孤岛检测技术中的主动频移法和滑模检测法,并进行了相应的仿真验证和比较,针对经典孤岛检测技术中的检测盲区限制问题,提出了一种基于间歇混沌理论的孤岛检测技术,并进行了参数的选择及仿真,结果显示,方法有效解决了分布式并网发电系统并网电压突变情况下的系统保护问题,该方法对保证分布式并网发电系统的安全稳定运行,提高系统的可靠性,有一定的参考价值。For the distributed grid system encountered island effect,this paper firstly introduces the traditional technique of active islanding detection method and sliding mode frequency shift detection method,and makes the corresponding simulation verification and comparison. In view of the blind spot limit in the classic island detection technology,an intermittent chaos theory islanding detection technology is proposed in this paper,and conducts a parameter selection and simulation,the results show that the method effectively solves the distributed grid system and network voltage mutation case system protection issues,the program ensures the safe and stable operation of distributed grid system and,improves system reliability,there is some reference value.
