Abstract

The invention provides a photovoltaic power station cable length optimization method and device and a cable model selection method and device, and the photovoltaic power station cable length optimization method comprises the steps: obtaining the arrangement information and on-site pile foundation data of a photovoltaic power station, wherein the arrangement information comprises the position of photovoltaic equipment, the position of a support, the type of the support and the length of the support; generating a pile foundation point according to the field pile foundation data, the bracket position and the bracket length; generating an optimal string outgoing point of each string on the bracket according to the bracket type, the position of the photovoltaic equipment and the pile foundationpoint, and generating a unified outgoing point of each row of brackets according to the position of the photovoltaic equipment and the pile foundation point; and calculating the length of an incomingcable according to the optimal string outgoing point and the unified outgoing point. According to the technical scheme, the calculation precision of the cable length can be improved.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic power station design and layout, in particular to a photovoltaic power station cable length optimization method, cable type selection method and device. Background technique [0002] In the design of photovoltaic power plants, the length of cables will not only affect the loss of power generation, but also affect the construction cost. Among them, the incoming cable of the combiner box or inverter is 4mm from the group string on the bracket to the combiner box or inverter 2 There is a lot of room for optimization in DC cables. [0003] At present, in the layout of photovoltaic power plants, it is often estimated that 4mm is based on the arrangement of photovoltaic modules on the string and the position of the combiner box or inverter 2 The length of the DC cable is estimated to be 4mm only based on the information on the floor plan 2 The length of the DC cable is roughly estimated,...
