It simulates the faults states of electric power system which includes faults on load-side, faults on system-side and cut-load.
利用MATLAB/SIMULINK建立三相四线APF的仿真模型,对其在电力系统故障状态下的运行行为进行仿真,包括负载侧发生各种故障、系统侧发生各种故障以及突然甩负荷等情况下的仿真,分析了系统在不同故障状态下对有源电力滤波器工作性能的影响,为研制实用化的三相四线有源滤波装置提供了理论支持。
By means of the judgement of the difference between failure volume , the switch beside the fault point is quickly tripped ,and the area not in fault is turned to normal .
本文介绍了一种通过GPRS通信的馈线自动化系统故障定位方式,通过对故障状态量差的判断,迅速跳开故障点两侧的智能开关,恢复非故障区域的供电,实现了馈线系统故障的一次性隔离。
Based on sorting fault cases reasonably,fault state vector of case set was introduced and regarded as a symbol.
在对故障案例合理分类的基础上,引入案例集故障状态向量作为案例的分类标志,引入案例发生频率以实现相似案例的最终择优选择,将权重向量放在各个案例集中分别计算。
