Txheej txheem cej luam

Load hom:

Cov khoom siv hluav taws xob feem ntau yog nonlinear load.Switching cov khoom siv fais fab, khoos phis tawj, tshuab luam ntawv, tshuab luam ntawv, tshuab luam ntawv, TV, elevator, lub teeb txuag hluav taws xob, UPS, cua txias, LED zaub, thiab lwm yam., uas yog cov khoom siv hluav taws xob tseem ceeb hauv kev faib hluav taws xob system ntawm kev lag luam thiab pej xeem chaw.cov khoom siv no muaj lub peev xwm me me, tab sis muaj qhov loj, nws muaj kev cuam tshuam zoo rau lub zog zoo.Muaj ntau cov khoom siv ib-theem, thiab nws cov khoom siv hluav taws xob muaj txog li 70% ntawm tag nrho cov peev txheej.Kev siv cov khoom siv hluav taws xob ib zaug ua rau tsis sib npaug ntawm peb theem kev faib khoom, ntau dhau tam sim no hauv cov kab nruab nrab, thiab offset ntawm qhov nruab nrab.Nonlinear loads muaj cov ntsiab lus siab sib haum xeeb thiab tsis tshua muaj zog.

Txais kev daws teeb meem:

adopting series reactor + fais fab capacitor txoj kev, uas tuaj yeem cuam tshuam kev cuam tshuam ntawm kev sib haum xeeb ntawm lub hwj chim capacitor thiab txhim kho kev pab cuam lub neej thiab kev ntseeg siab ntawm cov khoom.Nws raug nquahu kom siv cov ntse ntse ua ke los tiv thaiv kev sib raug zoo tsis tshua muaj hluav taws xob hluav taws xob hluav taws xob hluav taws xob (Kev daws teeb meem 1), Raws li lub zog zoo ntawm cov ntawv thov tshwj xeeb, siv cov lim dej (APF) / static reactive fais fab generator (SVG), reactive zog them thiab lub zog zoo. kev tswj hwm yuav zoo dua (Kev daws 2).
