摘要

目前的光伏支架结构都不能完全解决太阳能发电的稳定性与连续性问题。对此

本文提出一种新型面板可折叠跟踪式光伏支架。针对海南省特殊的强风天气

建立了一座并网式光伏电站模型。考虑海南当地气象环境

分析作用在光伏支架上的载荷

采用有限元方法对光伏支架进行静力学分析。为掌握光伏支架结构的动力特性

对其进行模态分析

计算了光伏支架前6阶模态。结果表明:该支架具有智能追光和主动避风的功能

解决了传统杆式追光光伏面板支架刚度小、抗风能力差的问题;采取光电式与程序式混合的追光模式来检测太阳光的高度和方位

在确保追光系统精度的同时

还具有较高的稳定性;在水平风和垂直风作用下

该自适应光伏支架能满足12级风速下的强度要求;第一阶频率9.84 Hz

远大于实际风的频率

不易引起风致共振的破坏

具有较好的稳定性。

Abstract

The current PV support structure can not completely solve the problems of stability and continuity of solar power generation.In this paper

a new type of panel foldable tracking photovoltaic support is proposed.In view of the special strong wind weather in Hainan Province

a grid connected photovoltaic power station model is established.Considering the local meteorological environment in Hainan Province

the load on the photovoltaic support is analyzed

and static analysis of the photovoltaic support is carried out by finite element method.To grasp the dynamic characteristics of photovoltaic support structure

the first six modes of the photovoltaic support are calculated.The results show that

this support has the functions of intelligent light tracing and active wind avoidance

which solves the problems of low rigidity and poor wind resistance of the traditional pole type light tracing photovoltaic panel bracket.Adopting the hybrid light tracing mode of photoelectric and program type to detect the height and orientation of sunlight can not only ensure the accuracy of the light tracing system

but also maintain high stability.Under the action of horizontal wind and vertical wind

the self-adaptive photovoltaic support can meet the strength requirements of 12-level wind speed.The first order frequency is 9.84 Hz

which is far higher than the actual wind frequency

it is not easy to cause the damage of wind-induced resonance and has good stability.
