The present invention discloses a method for detection and protection of an island with an anti-theft and anti-tripping function aiming at large-scale wind power. The method comprises: initializing a node type table and a node connection table; monitoring breaker tripping signals in a power grid, updating the node connection table according to the monitored breaker tripping signals, and starting a anti-theft and anti-tripping function module at the same time; and determining whether an island is formed or not according to the updated node connection table. Aiming at a large-scale wind power generation system, the island detection and the protection from an island are performed at the high-voltage main grid of the power supply, and therefore the method for detection and protection of island with an anti-theft and anti-tripping function aiming at large-scale wind power is rapid, accurate, efficient, safe and stable. According to the technical scheme, the method for detection and protection of island with an anti-theft and anti-tripping function aiming at large-scale wind power does not need to consider the line weight and can rapidly perform protection from an island.
