摘　　要：从理论上推导了线性负载不产生谐波、非线性负载将吸收的部分基波功率转变为谐波功率注入系统，从而成为系统的谐波源。文中还对线性负载及非线性负载电能计量的准确性和合理性进行了探讨，最后提出了一种合理收取电费的数学模型。In this paper it is deduced theoretically that linear load cannot generate harmonics and non－linear load becomes harmonic source because of its translating part of fundamental power absorbed from power system into harmonic power injecting the power system． The accuracy and rationality of electric power measurement for linear and non－linear load are explored． A rational mathematical model of electric rate is developed．

关 键 词：线性负载 非线性负载 电能计量 谐波
