Yintoni uKhuseleko lwaMandla okubuyisela umva weSeti yeGenereyitha

Njengomnini kunye nomsebenzisi wesethi yejenereyitha, umsebenzisi kufuneka aqonde yonke imiba yesethi yejenereyitha, ukuze alawule ukusebenza kunye nokusetyenziswa kweendlela zeseti yejenereyitha.Namhlanje inkampani ye-Dingbo Power yabelana ngokukhusela umva wokhuseleko kwiseti yejenereyitha.

Iseti yejenereyitha umva ukhuseleko lwamandla ikwabizwa ngokuba ngukhuseleko lwesalathiso samandla.Ngokuqhelekileyo, ulwalathiso lwamandla ejenereyitha kufuneka lusuke kwijenereyitha ukuya ebhasini.Nangona kunjalo, xa i-generator ilahlekelwa yi-excitation okanye ngenxa yesinye isizathu, i-generator inokutshintsha ekusebenzeni kwe-motor, oko kukuthi, ukufunxa amandla asebenzayo kwi-system, eyi-reverse power.Xa amandla angasemva efikelela kwixabiso elithile, ukhuseleko lwejenereyitha lusebenza, okanye lusebenze umqondiso okanye uhambo.

Ukusebenza ngokunxuseneyo kweeseti ezimbini zejenereyitha yedizili ziya kuhlangabezana neemeko zesigaba esifanayo sombane wejenereyitha, amaxesha afanayo ijenereyitha yombane kunye nokulandelelana kwesigaba esifanayo sesethi yejeneretha.Kusetyenziso lokwenyani, xa iiseti ezimbini zejenereyitha yedizili zihambelana ngaphandle komthwalo, kuya kubakho ingxaki yomahluko wefrikhwensi kunye nomahluko wombane.Ngamanye amaxesha awona mandla angasemva aya kufunyanwa kunye nesixhobo sokubeka iliso, esingamandla angasemva abangelwa ngumbane ongalinganiyo.Omnye ngumsebenzi obuyela umva obangelwa yisantya esingahambelaniyo (i-frequency).Ngokubhekiselele kwesi siganeko, uhlengahlengiso oluhambelanayo kufuneka lwenziwe.

1.Ukulungelelaniswa kwamandla okubuyisela umva okubangelwa ngumahluko wombane.

Xa isalathiso semitha yamandla kuzo zombini iiseti ezivelisayo inguziro kwaye iammeter isenayo isalathiso sangoku, iqhoshana lohlengahlengiso lombane lweseti yejenereyitha yedizili inokulungelelaniswa ngokwesalathiso seammeter kunye nesixhobo samandla.

2.Ukulungelelaniswa kwamandla okubuyisela umva okubangelwa rhoqo.

Ukuba ii-frequencies zeyunithi ezimbini zihluke kwaye umehluko mkhulu, i-current unit enesantya esiphezulu ibonisa ixabiso elihle kwaye imitha yamandla ibonisa amandla afanelekileyo.Ngokuchasene noko, okwangoku kubonisa ixabiso elibi kwaye amandla abonisa ixabiso elibi.

Ngeli xesha, lungisa isantya senye yeesethi ze-diesel generator kwaye ulungelelanise isalathisi semitha yamandla kwi-zero.Nangona kunjalo, xa i-ammeter isenayo isalathiso, le yimeko yamandla ebuyela umva ebangelwa ngumahluko wombane.

Kwiimeko ezininzi, udibaniso olunxuseneyo lweeseti zejeneretha yedizili aluyi kuvelisa amandla abuyela umva.Zimbalwa kuphela iijeneretha ezine-voltage ephantsi yokuphuma ngenxa yolawulo olungafanelekanga xa uqhagamshelwe kwigridi.Kufuneka sihlalutye oonobangela ngokukhawuleza kwaye sithathe amanyathelo afanelekileyo okulungisa.

Yintoni umsebenzi wokhuseleko lwamandla umva wejenereyitha?

Xa iiseti zejenereyitha zedizili ezingaphezu kwezibini zisebenza ngokunxuseneyo, ukuba i-injini yedizili yomnye iseti yedizili ayisebenzi ngokuqhelekileyo okanye iparalleli phakathi kwenjini yedizili kunye nejenereyitha yonakaliswe, iyunithi yejenereyitha ayinakukhupha amandla asebenzayo, kodwa ifunxa. amandla avela kwinkqubo yonikezelo lwamandla, kwaye ijenereyitha ehambelanayo iba yimoto ehambelanayo, oko kukuthi, ijenereyitha ehambelanayo isebenza kumandla angasemva.

Ukuba ijenereyitha ehambelanayo isebenza kwimeko yamandla ebuyela umva, ayilunganga kwinkqubo yonikezelo lwamandla, okukhokelela ekukhubekeni okugqithisileyo kwezinye iiyunithi ezithatha inxaxheba ukusebenza ngokunxuseneyo kunye nokuphazamiseka kombane.Ngoko ke, amanyathelo aya kuthathwa ukubuyisela umva ukhuseleko lwamandla.

Sinokusebenzisa isixhobo sokukhusela umbane we-transistor.

Kuba umva ukhuseleko lwamandla lukhuselo lwendlela yombane esebenzayo, isiginali yokufumanisa kufuneka ithathe imiqondiso yombane kunye neyangoku kunye nobudlelwane besigaba, kwaye iyiguqule ibe ngumqondiso wolawulo lombane weDC obonisa isalathiso kunye nobukhulu bamandla asebenzayo.

Isignali yokukhusela umbane yesixhobo ithathwa kwi-voltage kunye ne-current yesigaba se-S sejeneretha ukuze kubonwe umbane wesigaba esinye.Kwisekethe yokwenziwa kwamandla ombane, amacala aphambili eziguquli zamandla ombane i-M1 kunye ne-M2 aqhagamshelwe kwiinkwenkwezi ezilinganayo, kwaye i-voltage Uso' ikhutshwa njengophawu lombane.Kwaye wenze Uso' kwisigaba kunye nesigaba sombane we-USO ophumayo ngujenereyitha.Isignali yayo yangoku ifunyenwe yi-S-phase transformer yangoku kwaye ihlaziywe ngamacandelo amabini okulungisa ibhulorho yesigaba esisodwa VD1 kunye ne-VD2.Kwi-voltage ye-U1 ye-resistor R3, i-voltage U2 ye-resistor R4 kunye nekhonkco lokubona amandla, umgaqo wokuthelekisa ixabiso elipheleleyo liya kusetyenziselwa ukufumanisa.Xa i-R1 = i-R2, i-DC yolawulo lwe-voltage yesignali ye-UNM iphuma ngekhonkco lokubona amandla ilingana ngokuthe ngqo kumandla asebenzayo P kwaye ibonakalisa isalathiso se-P. Ngamandla angasemva, i-DC yolawulo lwe-voltage yesignali ye-UNM ayilunganga, oko kukuthi, i-N -Ithuba lenqaku liphezulu kunesakhono se-m-point.Xa amandla angasemva afikelela kwi-8% yamandla alinganisiweyo we-generator, i-triode VT1 ivuliwe kwaye i-VT2 icinyiwe.Umbane osebenzayo ubiza i-capacitor C ngokusebenzisa i-resistators R15 kunye ne-R16, kunye nokulibaziseka kokutshaja malunga ne-5s.Xa i-voltage yokutshaja ye-capacitor C ifikelela kwi-voltage yokuqhawula yombane wokuzinzisa ityhubhu W1, ityhubhu ye-W1 ivuliwe, i-diode VD3 kunye ne-triode VT3 ivuliwe, i-outlet relay D1 ivuliwe kwaye isebenza, kwaye umbane wokuhambisa umbane uhamba ngokuzenzekelayo, ngoko ke. ukuphumeza injongo yokhuseleko.
