摘　　要：基于面向对象技术的Visual C++语言为开发环境,开发了电力系统谐波潮流计算程序,利用该程序对某地区的风电机组接入电网后所产生的谐波进行评估,计算并网点电压、电流的总畸变率,确定山西某地区的风电场接入系统公共连接点PCC(point of common coupling)处的谐波畸变情况。由于公共连接点处的谐波畸变值超过了国家标准(GB/T14549-93)规定的允许值,因此,必须在公共连接点处加装滤波器进行谐波抑制。With the increasing scale of wind power,the influence of wind power harmonic on power grid has become more and more obvious and has restricted the capacity and scale of wind power.Using Visual C^＋＋ program based on object-oriented technology,a calculation program of power system harmonic flow was developed.Using the program,we can calculate the harmonic generated by the wind power connected into power system,the total distortion rate on voltage and current at the point of common coupling（PCC）,and analyze the distortion condition of harmonic at PCC. Because total harmonic distortion of PCC exceeds the national standard of harmonic （GB/T 14549-93）, it is necessary to install filter to suppress harmonic.
