Because massive harmonic interference in the electrical network, it causes signal - sampling to include the very big harmonic in the measurement system, for eliminating measurement result influence by harmonic, the paper has an in - depth study of fourier transformation harmonics analysis measurement principle, analysis the forming reasons of frequency spectrum leakage and railing effect during measurement, achieves phase locked loop and frequency multiplier technique to realize integer - period synchronous sampling and eliminate impact of frequency spectrum leakage and railing effect in the result of measurement, and investigates in depth theory on phase locked loop and frequency multiplier technique, gives the method of realizing phase locked loop and frequency multiplier technique
由於電網中存在大量的諧波干擾，導致測量系統中取樣信號也含有很大的諧波，為了消除諧波對測量結果的影響，論文深入研究了傅立葉變換諧波分析法的測量原理，分析了測量中頻譜泄漏和柵欄效應形成的原因，提出了採用鎖相環倍頻技術實現信號的整周期同步采樣，消除頻譜泄漏和柵欄效應對測量結果的影響，並對鎖相環倍頻技術的理論進行了深入研究，給出鎖相環倍頻技術的實現方法。 -
