以北京某户住宅为试验平台.调查该住宅单台家电及不同家电组合的谐波特性。通过模拟住户平时生活用电.测量该户配电箱总进线处的谐波数据,并进行拟合,得出该户电流总谐波畸变率THDi随用电负荷增加而减小的变化曲线。最后通过对深圳、上海两地住宅用电负荷与电流总谐波畸变率的测量,验证该拟合公式的合理性。
以北京某戶住宅為試驗平檯.調查該住宅單檯傢電及不同傢電組閤的諧波特性。通過模擬住戶平時生活用電.測量該戶配電箱總進線處的諧波數據,併進行擬閤,得齣該戶電流總諧波畸變率THDi隨用電負荷增加而減小的變化麯線。最後通過對深圳、上海兩地住宅用電負荷與電流總諧波畸變率的測量,驗證該擬閤公式的閤理性。

Taking a household in Beijing as an example for experiment, this paper investigates the harmonic characteristics of a single household appliance and different combinations of household appliances. By simulating normal household power utilization, we measure the harmonic data of the total inlet line of the distribution box for the household, fitting the data and get the variation curve that total harmonic distortion of current THDi of the household decreases with the increase in electricity load. Finally, through measurement of electricity load and total harmonic distortion of current of household in Shenzhen and Shanghai, the reasonability of the fittinu formula is verified.
