NAND Flash has become the most widely used electronic stable storage technology for embedded systems. As on-board storage capacity increases, the need for efficient indexing techniques arises. Such techniques are very challenging to design due to

鉴于分布式光伏发电井网系统的电压稳定性对现实生话有重要意义.从下程角度给出380/220 V低压 配电网电压失稳的实用判抓.运用I SC 八I>软件构建了一个分布式光伏电源接入0. } kV配电网的3竹点系 统仿真模型.在此基础上分析了负荷增加、光照强度突降、环境温度增大以及负荷母线发生短路故障等扰动对 负荷电压稳定性的影响。仿真结果表明.当负荷电压接近电压稳定限定伯正常运行时.光照强度突降会使负 荷母线电压失去稳定:温度变化对负荷电压的影响甚微:短路故障消除后负荷母线电压
