触发式最小电流扰动的孤岛检测方法研究
Island Detection of Triggered Minimum Current Disturbance
摘要
Abstract
According to the periodic change of the output power of the grid connected inverter, a method of minimum current disturbance detection was proposed. When the low-voltage circuit breaker was sepa-rated from the power grid, the arc signal generated was used as the trigger condition, and the minimum current disturbance was activated to detect the phenomenon of the isolated island. According to the Std. 929-2000 IEEE technology, this method was simulated and studied, and the validity of the method was verified. The research results showed that this method not only had no blind area, but also greatly re-duced the time of adding disturbance, which changed the running state of the inverter in overload or un-der load, and improved the service life of the inverter.关键词
