摘　　要：为了保证高海拔寒冷地区冬季风电基坑在完成浇筑作业后达到最佳的固化效果(基坑温度大于5℃,养护持续时间48 h),利用自行设计的光伏移动发电系统连接负载储热式电暖器为风电基坑保温。首先进行供热设备用电理论计算,并通过PVsyst仿真软件模拟,确定供热设备功率及数量,再进行供电计算,确定光伏移动发电系统装机容量,最后进行实证分析。结果表明该光伏系统完全满足供电需求。In order to ensure that the wind power pit achieves the best curing effect after completing the pouring operation in the winter of high⁃altitude cold regions(pit temperature is more than 5℃,maintenance duration 48 h),the self⁃designed photovoltaic mobile power generation system connected to the loaded thermal storage electric heater is utilized to insulate the wind power pit.Firstly,the theoretical calculation of power consumption of heating equipment is carried out,and simulated by PVsyst simulation software to determine the power and quantity of heating equipment,then the power supply calculation is carried out to determine the installed capacity of the PV mobile power generation system,and finally the empirical analysis is carried out.The results show that the PV system fully meets the power supply demand.
