摘　　要：大型离网风机与高耗能的海水淡化装置联合运行将是未来淡水清洁生产技术的开发方向之一。首先根据海水淡化的负荷特性及风电的运行特性,分析含风电、储能、海水淡化负荷的孤立微电网的运行模式及控制方案。在此基础上,根据风速历史数据,计算机组出力及风功率波动的概率分布,提出风电、储能和海水淡化装置的容量配置方案以及孤立微电网协调运行的控制策略,进而提高系统经济效益和安全稳定运行能力。最后基于PXI+c RIO的仿真试验系统搭建某地区海岛微电网,针对风电海水淡化孤立系统不同运行工况进行实时仿真,验证了所提控制策略的可行性。The combined operation of large-scale off-grid wind turbines and energy-intensive seawater desalination equipments will be one of the directions of the cleaner freshwater producing technology in the future. Based on load characteristics of seawater desalination devices and operating characteristics of wind power, the operation modes and control strategies of isolated microgrid with wind power, energy storage and seawater desalination equipments are discussed firstly. On this basis, the unit outputs and the probability distributions of wind power fluctuation are calculated according to historical data of wind speed, and then the capacity configuration of wind power, energy storage and seawater desalination devices and the coordinated control strategy of isolated microgrid to enhance the economical efficiency and stability of the system are proposed, respectively. Finally, a digital-analog simulation platform is built based on PXI＋cRIO. The real-time simulation result for various operating modes of this isolated microgrid system verifies the feasibility of the proposed control strategies.
