New energy grid-connected active anti-islanding system, method and equipment and computer readable storage medium

The invention discloses a new energy grid-connected active anti-islanding system, method and device and a computer readable storage medium, and the system comprises an intelligent circuit breaker which is provided with an S1 electrode and an S2 electrode, and is connected with the positive electrode and the negative electrode of a power grid side power supply; the first current sensor is electrically connected with the S1 pole of the intelligent circuit breaker and is used for collecting the current of a power grid side power supply in real time; and the second current sensor is electrically connected with the distributed power supply side power supply and is connected with the first current sensor in parallel. The control strategy is accurate and convenient, periodic disturbance interference on the power grid can be eliminated, effective integration can be achieved in the narrow space of the intelligent circuit breaker, and blind spots of passive anti-island detection can be overcome. 本发明公开了一种新能源并网主动防孤岛系统、方法
