The embodiment of the invention discloses a method, a device and equipment for determining a current collection line of a mountain photovoltaic power station. The method comprises the steps: determining the shortest road and the shortest road length between every two pieces of power station equipment based on road information of a photovoltaic power station and position information of the power station equipment, wherein the equipment comprises a booster station and a box transformer substation; constructing a total cost model based on the shortest road and the road length; performing optimization calculation on the box transformer substation sequence according to a preset optimization algorithm and the total cost model, and determining a current collection line topology with the lowest cost. According to the embodiment of the invention, the road between the power station equipment is optimized, so that the design that the cable is laid along the road can be met, the distance between the equipment is the shortest distance along the road, and the connection mode of each current collection line is the connection with the lowest comprehensive cost; moreover, the method provided by the embodiment of the invention can be automatically calculated by equipment such as a computer, and has the advantages of high efficiency and short design period.
Description
technical field [0001] Embodiments of the present invention relate to collector line technology, and in particular to a method, device and equipment for determining a collector line of a mountainous photovoltaic power station. Background technique [0002] In the photovoltaic power station, the box transformer in the power generation unit of the photovoltaic factory is connected to the booster station through the collector line. When the position of the box transformer, the location of the booster station and the number of collector lines are determined, it is necessary to design the connection of the collector line The method (which box-type transformers are connected to a collector line, and the connection topology between the box-transformers in a collector line), different connection methods of collector lines will cause differences in the selection and amount of cables, and ultimately affect Therefore, it is necessary to optimize the design of the collector line to redu...
