摘要
复杂地形条件下光伏电站的多联动平单轴系统与常规的多联动平单轴系统之间存在较大区别,前者对设计、施工提出了更高的要求。分析复杂地形下光伏电站多联动平单轴系统的布置难点,因地制宜采取多种支架形式组合的方式,通过微地形分析及桩顶高程差异化设计,提出适应于复杂地形的布置方法,解决了在不做大范围场平条件下联动内桩长控制及桩顶共面的问题。研究结果满足复杂地形多联动平单轴系统的设计及施工要求。
There is a big difference between the multi-linkage flat single-axis system and the conventional multilinkage flat single-axis system of PV power station in complex terrain,and the former put forward higher requirements for the design and construction.The paper analyzes the difficulties of multi-linkage flat single-axis system in complex terrain.Terrains and combination of different kind of bracket are fully considered,the general layout with a higher degree of terrain adaptation is proposed.According to the analysis of microtopography and the differential design of pile top elevation,the problem of the control of pile length and the coplane of pile top is solved under the condition of no large range of field grading.The research results meet the design and construction requirements of multi-linkage flat single axis system in complex terrain.
