电网中的谐波电压和电流本身也是一种能源.利用基于磁通可控可调电抗器原理隔离系统谐波,迫使谐波流入谐波提取侧,通过三绕组变压器和基波磁通有源补偿在不取用系统基波功率的条件下提取含量较大的谐波分量.将提取出的谐波能量直接进行利用,或转化为直流或逆变成交流回馈电网,达到谐波利用的目的.利用MATLAB6.5搭建实际系统模型并对谐波提取进行仿真分析,仿真结果表明在谐波含量较为丰富的地方,本方案能有效滤除和提取电力系统谐波进行利用.

The harmonic voltage and current in the grid itself is also a kind of energy.Make use of the principle of magnetic flux controllable and adjustable reactor to isolate the system harmonic,which can reduce system harmonic distortion rate and forced into harmonic extraction side,then through the three winding transformer and fundamental wave flux compensation in the condition of without using fundamental power to extract the large content of harmonic component.The harmonic energy can directly use,or converted to dc or inverted to ac to return to the power grid.Use MATLAB6.5 to build the real system model and to do simulation research,the simulation results proves the scheme can effectively filter and extracting power system harmonic for use where harmonic content is relatively rich place.
