基波功率的英文
例句与用法
- It is deduced theoretically that non - linear load , rather than linear load , generates harmonics , which translates part of fundamental reactive power absorbed from power system into harmonic reactive power injected into the power system . the rationality of electric power measurement for linear and non - linear load is studied , and as a result some rational advices are addressed here
从理论上推导了线性负载不产生谐波，非线性负载将吸收的部分基波功率转化为谐波功率注入系统，并对电能计量准确性和合理性做了一些探讨，最后提了一些无功的收费意见。 - 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。
