摘要
为克服直接谐波计算方法的缺点,采用改进算法对独立电网中多个整流器在公共接入点PCC上产生的谐波进行了评估。该方法是在直接谐波计算法基础上通过进一步的校正计算而形成,这样就可以克服直接计算方法因不能考虑谐波电压产生的电流而引起的误差问题,具有较高的精度,而且此方法还免去了迭代计算法复杂的迭代过程,特别适合于对多变换器进行谐波计算。最后仿真与计算结果的比较验证了这种方法的可行性。
An improved direct harmonic analysis method is introduced to evaluate the PCC harmonics with multi-rectifiers in isolated power systems. The method is formed by adding a further emendation calculation on the basis of direct harmonic analysis, it can overcome the shortcomings without consideration of harmonic voltage, and makes the precision more higher. Moreover, this method can exclude the intricate iterative process, and is fit for harmonic analysis for multi-converters. The comparison of simulation with analysis result reveals the feasibility of the method.
