摘要
分析非线性负载和冲击性负载对电能质量的影响,给出符合电网信号实际情况的、适用范围更宽的基于随机过程理论的电网信号数学描述.并据此分析了现有电能计量方法产生巨大误差的原因,提出解决问题的方案,给出仿真结果,对提高现有电能计量水平有一定的参考价值.
This article analyzed the influence of the non - linear loads and the impact loads to the power quality, and produced electric network signal mathematics description that based on the stochastic process theory. It has conformed to the electric network signals＇ actual situation and the wider applicable scope, analyzed the reason why the existing electric energy measuring method has a huge error, proposed solved the problems plan and gave the simulation results. To raise the level of the existing electric energy measurement, it has a very good practical value.
