Txoj kev los txhim kho lub zog zoo

There are many devices and measures to improve power quality. New devices with high-power power electronic devices as core units can be used to effectively suppress or offset various short-term and transient disturbances in the power system, while conventional measures are well suited for steady-state voltage adjustment. Power quality control devices can be divided into the following three categories according to their functions: reactive compensation devices, filters, and ua kom muaj zog ua kom zoo (UPQCS) uas tsom rau kev tswj hwm cov khoom siv hloov chaw, nws yog qhov tsim nyog los txais cov ntaub ntawv muaj tseeb thiab kev tswj hwm}} Txheeb xyuas cov ntaub ntawv hluav taws xob, thiab tom qab ntawd txheeb xyuas cov ntaub ntawv no hauv lub sijhawm thiab nrawm nrawm} Cov ntaub ntawv tswj tau tsim nyog siv los ua cov nyiaj uas xav tau tsim nyog
1. extraction ntawm kev cuam tshuam ntawm kev cuam tshuam
Rau cov teeb meem muaj zog xws li kev sib txuas lus thiab cov kev sib raug zoo, cov sijhawm siv tau yooj yim, thiab cov sijhawm ua kom haum xeeb Lub sijhawm ntev, thiab tsis tuaj yeem ua tiav qhov tiag tiag-{4}} Tsis muaj kev tswj hwm lub luag haujlwm hauv kev tswj hwm lub teeb meem ua lub hauv paus ntawm spectrum tsom xam thiab kev txheeb xyuas kev ua kom zoo {{}}
Rau cov kev ntxhov siab zoo xws li Volfage poob, hluav taws xob muaj kev cuam tshuam nrog lub sijhawm, thiab siv hluav taws xob luv luv, yog li cov teeb liab kev hloov pauv tau, ua ke cov qauv tshuaj ntsuam tseem yog ib qho qauv hauv kev tshawb xyuas cov teeb meem kev tshuaj xyuas cov teeb meem zoo .
Kev tshawb nrhiav thiab tsom xam ntawm cov qauv kev ntsuas lub zog muaj zog, cov kev kuaj pom kev sib cav sib ceg raws li cov kev ntsuas lim dej kev tshawb xav, thiab lwm yam . Txuas ntxiv cov txheej txheem raws li cov txheej txheem kev saib xyuas tam sim no raws li kev sib cais ntawm theem et al. Nyob rau hauv 1984 muaj qhov kev hloov pauv ntawm cov khoom siv hluav taws xob uas tsis yooj yim harmonic tam sim no muaj tseeb dua thiab hauv lub sijhawm tiag tiag.
2.} Tswj lub tswv yim
Thaum cov ntaub ntawv muaj zog tau raug kuaj pom zoo thiab tshuaj xyuas cov ntaub ntawv no {{} Txoj kev tswj hwm tau cuam tshuam nrog hom teeb meem zoo thiab cov khoom tswj.
Qee cov khoom siv tsoos siv rau cov teeb meem hluav taws xob-kev hloov kho, muaj cov khoom siv shunt kev . Lawv cov tswv yim tswj hwm suav nrog kev tswj hwm qhib-voj thiab ntse tswj .
Muaj ntau txoj kev tswj hwm rau cov kev tswj hwm cov khoom siv hluav taws xob muaj zog ntawm cov hloov pauv), Dynic parter generator), UPTQC, etc {{} Lub PWM tswj cov thev naus laus zis rau Cov hloov pauv tam sim no yog cov kev tswj hwm feem ntau} los ntawm cov teeb meem thiab cov teeb meem hluav taws xob tsis sib haum xeeb yog txiav txim siab . tam sim no, tus tswj txoj kev uas tau kawm dav thiab thov yog li nram no:

a.PID tswj: Qhov no feem ntau siv cov qauv hauv lub zog kev lag luam, thiab yooj yim rau kev tswj hwm kev txhim kho, thiab yooj yim txhim kho kev ua haujlwm zoo thiab khov kho ntawm lub system . Txawm li cas los xij, muaj peev xwm tswj tau xws li kev sib txuas ua ke thiab tswj tau cov kev sib txuas nrog cov qauv hluav taws xob tswj tau tshwm sim.
b.Hysteris piv kev tswj: Tam sim no, feem ntau siv tus qauv ntawm kev hloov pauv ntawm lub sijhawm nrawm nrawm nrawm, kev tswj hwm siab tau raug, yooj yim Kev siv thiab tsis tas yuav nkag siab txog kev thauj cov yam ntxwv; Qhov chaw tsis zoo tseem ceeb yog tias qhov hloov zaus tsis tas kho, muaj lwm txoj kev sib txuas nrog Vector kev tswj hwm thaum siv tau zoo rau cov neeg ua haujlwm tau zoo .
c.Chaw Chaw Vector Tswj: Tus txheej txheem ntawm qhov chaw Vector yog kom tau txais cov kev ntsuas ua kom muaj kev sib koom tes ua ke, thiab muaj kev sib koom tes zoo nkauj. kev ua haujlwm, uas feem ntau ua los ntawm DSP; Txhawm rau kom luv luv lub sijhawm ua haujlwm tiag tiag thiab txo cov kev cai rau cov khoom siv, qee cov txheej txheem yooj yim tuaj yeem siv .
d.Kev tswj lub luag haujlwm: K . p} Kuv lub ntsiab lus tseem ceeb los ua kom tiav cov zis kom muaj nuj nqis rau cov lus tawm tswv yim kom muaj nuj nqis}. tus Kev siv cov kev tswj lub plhaw tuag tuaj yeem tshem tawm cov kev ua tsis ncaj-hauv lub xeev thiab xaus cov kev hloov pauv hauv lub sijhawm luv luv; Txawm li cas los xij, nws tseem muaj qhov tsis zoo xws li kev tswj hwm lub hnub nyoog uas muaj kev cuam tshuam nrog kev tswj hwm lub hnub tuag lossis kev ua tau zoo tshaj plaws ntawm kev tswj hwm lub hnub tuag.
e.Cov lus tawm tswv yim linearization: Tus qauv ncaj qha Linearization (DFL) los hloov cov kab ke ntawm cov kab ke tsis yog los ntawm kev tswj hwm txoj kev xav .
f.Nonlinear tswj: xav tias smes (superconducting zog txoj cai lij choj, thiab tom qab ntawd txoj cai tswjfwm tsis muaj peev xwm siv tau los tswj; lossis lub zog tswj kev xav tuaj yeem siv ncaj qha los tsim cov maub los yog H∞ tswj hwm kev ua haujlwm ntawm Canada thiab tau dhau los ua cov cuab yeej ua kom muaj zog rau kev txheeb xyuas thiab tsim kev tsis paub meej Tshuab .
g.Kev Tswj Xyuas Kev Lag Luam: Qhov tseeb smes system yuav cuam tshuam los ntawm kev hloov pauv ntawm txoj kev hloov pauv tau los ntawm kev ua haujlwm zoo rau kev ua haujlwm hauv lub sijhawm ua haujlwm hauv online, thiab tom qab ntawd hloov kho cov qauv tsis hloov hauv online thiab tswj cov txuj ci kom ua tiav qhov siab-precision tswj .
h.Fuzzy logic tswj: Thaum tsim ib tus maub los siv txoj kev tswj hwm thiab kev tswj hwm tus kheej tau muaj txiaj ntsig zoo ntawm cov ntaub ntawv raug cai, lawv xav tau kev tswj hwm tus kheej ntawm cov ntaub ntawv ua ntej thiab xav tau kev txheeb xyuas tus kheej online ntawm cov qauv . cov algorithm yog cov qauv kev tswj hwm ua lej, uas tau hais kom muaj cov yam ntxwv zoo thiab muaj cov yam ntxwv zoo nkauj thiab cov yam ntxwv zoo txo qis . fuzzy tswj tau muaj zog rau kev tswj hwm sab nraud, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev tswj hwm tau ua ke, xws li cov qauv kev sib hloov, xws li cov qauv kev sib hloov, xws li cov qauv kev hloov pauv thiab cov khoom siv cuav neion networks, txhawm rau txhim kho kev ua tau zoo ntawm fuzzy tswj .
i.Cov khoom siv neural neural (Ann): Kev sib raug zoo nkauj tsis muaj kev sib raug zoo thiab cov zis raws lawv yam tsis muaj kev xav tau tus qauv lej ntawm cov qauv; Qhov txhaum kev kam thiab hloov kho tau ntawm Ann tuaj yeem tiv nrog ntau cov kev ua haujlwm ntawm kev ua haujlwm ntawm kev tawm tsam kev cuam tshuam ntawm cov kab ke; Lub hauv paus ntxig sib piv thiab ua kom muaj peev xwm ua tau cov peev xwm ntawm Ann pab nws kom cov txheej txheem sai sai
Nyob rau hauv luv luv, cov nyiaj tsis txaus thiab tsis txaus ntseeg yog ib qho tseem ceeb ntawm cov kev txwv tsis pub siv cov kev txwv {}} e {}, lub zog saib xyuas thiab kev txhim kho System {{4 4}} nws tau tsim ib qib kev tswj hwm zoo li cas, thiab tom qab ntawd nws siv tau cov kev ntsuas hluav taws xob zoo thiab tswj hwm thiab kev sib txuas lus siv thiab kev sib txuas lus thev naus laus zis rau achieve management and control of all power distribution and power system facilities at the user end, including power supply lines to terminal power equipment, at an economically reasonable cost, greatly improving the operation and management efficiency of power distribution and power systems and facilities, and reducing operating costs.
