摘要
海南偏远地区配电系统采用微电网供电,利用当地丰富的风光资源进行发电,在兼顾改造成本的前提下,实现无缝计划型离网转并网运行模式的切换,可靠地为当地居民进行不间断供电。对微电网的运行方式及控制原理进行介绍,从系统工作原理和断路器改造成本两方面阐述微电网离转并改造设计方法。
Micro-grid power supply is taken by distribution systems in remote areas of Hainan. Using the abundant renewable resources,and considering the cost of reconstruction,seamless switch of operation modefrom off-grid to grid-connectedis realized,which provide uninterrupted power to local residents reliably. The operation mode and control principle of micro-grid are introduced. The reforming program that switches regional microgrid from off-grid to grid-connected is represented from system working principle and breakerreforming.
