摘要
非线性负载在电网中引起电流和电压波形畸变,产生谐波电压和谐波电流。电网中谐波的存在对传统的电能计量系统产生影响,使计量不准确和不公平。就谐波对电网电能计量系统的影响进行了分析研究,并提出了谐波情况下提高电能计量精度的措施。
Nonlinear load causes the distortion of current and voltage waveform in power grid, and generates the harmonic voltage and harmonic current. The presence of harmonics in power grid will influence the accuracy of traditional electric energy metering. Its influences on the electric energy metering system are analyzed and studied. The measures for improving the accu- racy of electric energy metering are proposed.
