针对内蒙古的特定情况，采用以风力发电为主导的小型孤立发电系统提供电能，可保证供电可靠性、节省柴油燃料和保护当地的生态环境。本文所述的小型孤立发电系统以风/柴/储能联合发电的形式提供电能。文章采用序贯Monte-Carlo模拟法实现风/柴/储能发电系统的可靠性评估。根据风电场的风速历史数据，建立风电场的风速时间序列模型。由风速时间序列计算风力发电机的输出功率。在考虑机组随机故障的情况下，由发电机和负荷模型得到蓄电池的时间序列模型。针对样例系统，量化评估了仿真样本容量、蓄电池容量、蓄电池充放电率和风力发电机额定功率等，一些因素对风/柴/储能发电系统可靠性的影响。仿真结果可为风/柴/储能发电系统可靠运行提供依据，为政府及电力部门推广风/柴/储能联合发电向偏远地区供电提供依据。

For the specific situation of Inner Mongolia, use of small isolated power generating system of wind power-led to provide electric energy, can ensure reliability, saving diesel fuel and protect the local ecological environment. In this paper the small isolated power systems was described as Wind / diesel / storage power generating system. This Article use sequential Monte-Carlo simulation method to evaluate the system reliability. According to the historical data of wind farm, establish the wind speed time series model, than calculate the output of WTG. Considering the units random failure, use generator and load models to obtain the battery time series model. To a sample system, quantitatively assessment a number of factors that affect the system reliability, such as the simulation sample size, the battery capacity, the battery charging and discharging rate and the WTG rated power and so on. The simulation results can provide basis for the wind / diesel / storage system reliable operation, and for the government and the power sector to promote wind / diesel / storage co-generation system to remote areas.
