单回路整定，主要对象为锅炉汽水系统，所运用的方法为三冲凉控制。-Single-loop tuning, the main target for the boiler water system, the method used for the control of the three showers.

该仿真模型是用来提取单机无穷大系统发生故障短路各线路三相电压的最大值-The simulation model is used to extract single machine infinite bus system short-circuit failure of the maximum three-phase voltage of each line

MATLAB 软件是当今控制系统的设计与仿真中重要的工具软件。该软件仿真方便， 结果直观、准确。本文以单相桥式全波可控整流电路及三相桥式全波可控整流电路为例，叙 述了利用 MATLAB/SIMULINK对整流电路进行建模仿真的方法，并给出了仿真结果波形。 通过对仿真结果分析就可以将系统结构进行改进或将有关参数进行修改使系统达到要求的 结果和性能，这样就可以极大地加快系统的分析或设计过程。 -MATLAB software is the current control system

In this paper, we introduced a new series-shunt type FACTS controller called as distributed power flow controller to improve and maintain the power quality of an electrical power system. This DPFC method is same as the UPFC used to compensate the v
