摘要
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。
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.
