A Simulation Platform for Complex Electric Energy Metering Environment

随着电力电子技术的发展和应用,电源及负载的多样性使电力系统变得越来越复杂,也导致了电能的精确计量变得越来越困难。为了解决复杂工况下电能计量场景再现的难题,文章设计一种复杂电能计量环境模拟平台。该平台可将不同场景的电压电流波形数据在上位机中生成模拟波形,由功率放大器放大为功率电压和电流,在实验室再现特定的电能计量环境,并对待分析计量表与标准计量表的计量进行误差分析,达到对应场景下的电能计量方法的实验验证。该复杂电能计量环境模拟方法在某实际应用中取得了很好的效果,为以后复杂电网下的电能计量研究提供了参考。

With the development and application of power electronics technology,the diversity of power sources and loads makes the power system more and more complex,which also makes the accurate measurement of electric energy more and more difficult.In order to solve the problem of reproducing electric energy metering scenarios under complex working conditions,the paper proposes a method to implement a complex electric energy metering environment simulation platform.The method can generate the simulated waveform data of voltage and current of different scenarios in the host computer,and amplify them into power voltage and current by the power amplifier,and reproduce the specific electric energy metering environment in the laboratory,and analyze the error of the metering of the meter to be analyzed and the standard meter to achieve the experimental verification of the electric energy metering method under the corresponding scenarios.The simulation method of complex power metering environment proposed in this paper has achieved good results in a practical application and laid the foundation for future research on power metering under complex power grids.
