- To put into operation a large amount of non - linear load , make in harmony wave of rural power grids serious becoming in pollution , pass to rural local electric wire netting main in harmony analysis of wave source , put forward in order to restrain from insert rural power grids in harmony wave source voltage total in harmony wave distortion rate and the containing rate change last device number pulsating for increase of goal , increase the pulse of the current change device and install light specified value electricity active wave filter mix with passive wave filter near the harmonics source to control the wave in harmony
摘要大量非线性负荷的投运，使农村电网的谐波污染日趋严重，通过对农村地方电网主要谐波源的分析，最终提出了以限制接入农村电网的谐波源的电压总谐波畸变率和各次谐波电压含有率为目标的增加换流装置脉动数，以及在谐波源附近装设小额定值的电力有源滤波器配以无源滤波器的混合型电力滤波方式，以进行谐波治理。 - Different measurement standard produce the estimate for the meter ' s measurement error . the theoretic analysis shows that the non - linear load is harmonic source , and the harmonic produced by it is transformed by part of basic wave absorbed by it from power system , therefore , traditional measurement mode has some
通过对非线性负荷的理论分析表明，作为谐波源，非线性负荷所产生的谐波是吸收基波的一部分转化而来，从而说明传统的计量方式具有不合理性，提出相应的解决方法和对策，并建议一种新的电能计量方式供同行研究探讨。 - What the subject researching is that power energy should be measured with base wave ammeter to power systematic nonlinear user ; and that it is high veracious by base wave ac parameters measurement method to those not bad contaminative . it is well known that all kinds of ac parameters including of base wave and harmonics , but the content of harmonics in power systems increase largely with the mass disturbance to power using high - power electric equipment . which makes wave shape of voltage and current aberrence , so the measurement veracity and reliability decreased largely . at the same time brings out serious infuency to safe run of power system and electric equipment . the power which any non - linear loads consumes can be divided into two sides , one is base power absorbed in power and the other is minus harmonics power
本课题所研究的问题是针对电力系统非线性负载用户采用基波电度表来计量电能；而对谐波污染不严重的线性用户采用基波交流参数测量的方法仍然具有较高的准确性。众所周知，各种交流参量都包含基波和各次谐波，然而随着电力电子技术的迅速发展，大功率的用电设备对电网的干扰也是越来越严重，导致电力系统谐波含量迅速增长，使电压和电流的波形产生严重畸变，测量的准确性和可靠性都大大降低，同时也对电力系统和用电设备的安全运行带来严重的影响。任何一种非线性负载所消耗的功率都可以分为两部分，一部分为从电网中吸取的基波功率，另一部分则是负的谐波功率。
