摘要
在多谐波源的电力系统中,谐波源之间相互影响、相互干扰,研究谐波源之间的耦合机理及其权重计算对谐波源责任区分及谐波解耦有重要意义。将多谐波源系统分为集中式多谐波源系统和分布式多谐波源系统来讨论。对于集中式多谐波源系统,在高次谐波频率下,提出基于戴维南等效电路的多谐波源电力系统模型,并给出诺顿等效电路,然后利用偏最小二乘法估算耦合因子大小。对于分布式多谐波源系统,同样建立模型,估算谐波源互阻抗,给出耦合因子大小。最后,集中式多谐波源系统以5谐波源系统为例,建立了MATLAB仿真模型,计算耦合权重;分布式多谐波源系统以IEEE 13节点为仿真模型,给出耦合因子大小。
In the power system,the interaction and influence occur between multiple harmonic sources. The study of coupling mechanism and the calculation of coupling weight is very important in harmonic responsibility and harmonic decoupling. The multiple harmonic sources system is divided into concentrated and distributed system. For concentrated system,at high frequency,Thevenin equivalent circuit is proposed,and Norton equivalent circuit is given too.Then,partial least squares( PLS) is used to estimate coupling index. For distributed multiple harmonic sources system,the model is established to estimate mutual impedance and provide coupling index. Finally,the MATLAB model is built in concentrated system with 5 harmonic sources,and the distributed system utilizes IEEE 13 bus system as simulation model to calculate coupling weight.
