A Metering Method of Harmonic Energy Loss in Power Distribution Network

非线性负荷的日益增多使得非线性负荷用户在电网中引起的谐波电能损耗的计量成为供用电双方共同关心的问题。本文建立了配电网的谐波分析模型 ,讨论了谐波电能的产生和消耗途径 ,提出了非线性负荷用户在配电网中引起的谐波电能损耗的计量方法。理论分析表明 ,电网中的谐波电能损耗为用户的基波电能与实际所耗电能之差。

Harmonics originated from increasing nonlinear loads in power distribution network may cause excessive energy loss, and the metering of this loss is a much concern of utilities and consumers. A system model for harmonic analysis is established. Based on the model, the production and consumption of harmonic energy is described and a metering method for harmonic energy loss in power distribution network is presented. The theoretic analysis shows that the harmonic energy loss caused by a nonlinear load consumer is the difference between the fundamental energy and the total energy of the consumer.
