Optimization method and system of offshore wind plant current collection system obstacle avoiding path

The invention relates to an optimization method and system of an offshore wind plant current collection system obstacle avoiding path. The method comprises the following steps of: obtaining an obstacle region in offshore wind plant current collection system topology design, and utilizing a GIS (Geographic Information System) technology to carry out layer processing on the obstacle region; carrying out geometrization processing on the obstacle region processed by the GIS, and obtaining the minimum area rectangular bounding box of the obstacle region; determining the optimization starting point and end point of an obstacle region path, and determining a path region range according to the starting point and the end point; according to the path region range and the minimum area rectangular bounding box, obtaining a path visibility graph which contains the obstacle region; and utilizing an optimal path algorithm to search an optimal path for avoiding an obstacle on the path visibility graph, and finishing the offs
