  5. 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

    本課題所研究的問題是針對電力系統非線性負載用戶採用基波電度表來計量電能；而對諧波污染不嚴重的線性用戶採用基波交流參數測量的方法仍然具有較高的準確性。眾所周知，各種交流參量都包含基波和各次諧波，然而隨著電力電子技術的迅速發展，大功率的用電設備對電網的干擾也是越來越嚴重，導致電力系統諧波含量迅速增長，使電壓和電流的波形產生嚴重畸變，測量的準確性和可靠性都大大降低，同時也對電力系統和用電設備的安全運行帶來嚴重的影響。任何一種非線性負載所消耗的功率都可以分為兩部分，一部分為從電網中吸取的基波功率，另一部分則是負的諧波功率。
  6. With the broad application of the electrical and electronic technology in the industry branches and the power apparatuses, the number of non - linear loads is much more and more, and the capacity of them is biggish, so a mass of harmonic is injected into the power system, which produces the waves of voltage and current in power system to be aberrant seriously

    隨著電力電子技術在各工業部門和用電設備上的廣泛應用，非線性負荷數量越來越多，容量也越來越大，諧波大量注入電網，使電力系統電壓、電流波形發生嚴重的畸變。由於大多數儀器、儀表是針對工頻正弦波設計的，因而造成指示數據不正確。
