谐波对电能计量影响的研究

Experimental research of harmonic effect on electirc power measurement and the analytic software for measuring error

基于电力系统实时数字仿真系统(RTDS)平台对谐波的电能计量误差进行仿真实验和实测实验,建立能反映谐波功率含量与其实际误差之间关系的数学模型。引入BP神经网络对该模型进行逼近,利用VC++6.0开发"谐波电能误差计算软件"。

This paper takes advantage of RTDS to simulate and meter the influence of harmonic on energy measuring. Then establish the mathematic model that shows the relationship of harmonic power and its influence on energy measuring. The BP neural network is introduced to explain the mathematic model of the nonlinear relationship. An analytic software for harmonic energy＇s measuring error, is developed using VC＋＋ 6.0.
