Comment Compenser pour les Trois phases de D\u00e9s\u00e9quilibre?<\/h1>\n

Dans les installations industrielles, les centres de donn\u00e9es et les \u00e9nergies renouvelables, des centrales \u00e9lectriques, des “trois-d\u00e9s\u00e9quilibre de phases conduisant \u00e0 la flamb\u00e9e des pertes en ligne et de dommage mat\u00e9riel” est devenu un core mal de puissance globale des syst\u00e8mes. Selon IEEE 1159 normes, de 10% en trois phases d\u00e9s\u00e9quilibre peut r\u00e9duire le rendement transformateur de 6% et l'augmentation des pertes dans les c\u00e2bles \u00e0 200%. Cet article, bas\u00e9 sur des normes internationales telles que la CEI 61000-3-6 et ANSI C84.1, fournit une analyse en profondeur de la collaboration d'att\u00e9nuation des principes de r\u00e9acteurs et Static Var G\u00e9n\u00e9rateurs (SVG), avec inter-r\u00e9gional d'ing\u00e9nierie de validation des donn\u00e9es.<\/p>\n

Contenu<\/b><\/h2>\n

1. Les Causes de Trois-D\u00e9s\u00e9quilibre de phases et de quantifier les Pertes \u00c9conomiques<\/em><\/h3>\n

1.1 Les Causes Profondes:<\/strong><\/h4>\n
(1)Asym\u00e9trique De La Charge De La Connexion:<\/strong><\/h6>\n

Monophas\u00e9 de puissance \u00e9lev\u00e9e de l'\u00e9quipement (par exemple, des fours \u00e0 arc, machines de soudage) concentr\u00e9 sur une phase peut causer de la phase actuelle des diff\u00e9rences sup\u00e9rieures \u00e0 15%. Par exemple, un courant de phase atteint 300A, tandis que les deux autres phases ne sont 180A, ce qui entra\u00eene un d\u00e9s\u00e9quilibre de 40% (formule de Calcul: D\u00e9s\u00e9quilibre % = (Max Courant de Phase de la Moyenne Actuelle) \/ Moyenne du Courant \u00d7 100%).<\/p>\n

(2)Asym\u00e9trique De La Source De Tension:<\/strong><\/h6>\n

La grille du c\u00f4t\u00e9 de la tension de d\u00e9viations (par exemple, une baisse de 5% dans la Phase A de la tension) plomb in\u00e9gale des trois phases de distribution de l'alimentation (IEEE 1159-2019 limite standard: 2%).<\/p>\n

(3)La Faute Induite Par Le D\u00e9s\u00e9quilibre:<\/strong><\/h6>\n

Les sauts de ligne ou de mise \u00e0 la terre des d\u00e9fauts de provoquer de brusques changements d'imp\u00e9dance dans une phase, conduisant \u00e0 une hausse de la homopolaire de courant (jusqu'\u00e0 1,5 fois le courant de phase).<\/p>\n

1.2 Impacts Directs:<\/strong><\/h4>\n
(1)Neutre du Point de Maj:Surcharg\u00e9 neutre du courant de ligne (CEI 60364-5-52 stipule \u226430% de courant de phase) peut causer une surchauffe du c\u00e2ble ou m\u00eame des incendies.<\/strong><\/h6>\n
(2)Transformateur de Perte de Pouss\u00e9e:N\u00e9gatif-de la s\u00e9quence actuelle fausse la base de flux magn\u00e9tique, l'augmentation de pertes par courants de foucault de 200% (CEI 60076-1 des donn\u00e9es de test).<\/strong><\/h6>\n

\"5\"<\/a><\/p>\n

2. Fondamentaux de la R\u00e9mun\u00e9ration Principe des R\u00e9acteurs et des Strat\u00e9gies de S\u00e9lection<\/em><\/h3>\n

2.1 homopolaire R\u00e9acteur en Trois phases M\u00e9canisme d'\u00c9quilibrage de<\/strong><\/h4>\n
2.1.1 Principe Physique:<\/strong><\/h5>\n

Le z\u00e9ro-s\u00e9quence r\u00e9acteur augmente neutre imp\u00e9dance de la ligne, en limitant le flux de courant de d\u00e9s\u00e9quilibre. Lorsqu'un courant de phase est excessif, le r\u00e9acteur forces une partie de l'actuel retour par les deux autres phases, l'\u00e9quilibrage de la charge triphas\u00e9e.<\/p>\n

2.1.2 La Compensation Des Effets:<\/strong><\/h5>\n
(1) la ligne Neutre actuel de suppression:100A courant de d\u00e9s\u00e9quilibre est r\u00e9duite \u00e0 35A (65% de r\u00e9duction) avec un 50mH r\u00e9acteur.<\/strong>
\n(2) Transformateur de la r\u00e9duction des pertes:N\u00e9gatif-s\u00e9quence de composants de diminuer de 70%, r\u00e9duction de la base des pertes de 18% (IEC 60076-8 des donn\u00e9es de test).<\/strong><\/h6>\n
2.1.3 S\u00e9lection De Formule:<\/strong><\/h5>\n

Exemple: Pour supprimer 100A courant de d\u00e9s\u00e9quilibre dans une 400V, un syst\u00e8me de 6.4 mH r\u00e9acteur est n\u00e9cessaire (compatible avec la norme IEEE 3003.3 normes).<\/p>\n

2.2\u00a0Suppression d'harmoniques Effet de Filtre R\u00e9acteurs<\/i><\/strong><\/h4>\n
(1) la 3\u00e8me Harmonique \u00c9limination:<\/strong><\/h6>\n

Un r\u00e9acteur \u00e0 7% de la r\u00e9actance, en s\u00e9rie avec un condensateur, forme un 150 hz filtre coupe-circuit avec une imp\u00e9dance ratio de 20:1, la r\u00e9alisation de >85% du courant harmonique de l'att\u00e9nuation.<\/p>\n

(2) La Ligne Neutre D'Optimisation:<\/strong><\/h6>\n

Dans un centre de donn\u00e9es de cas, la ligne neutre courant a chut\u00e9 de 210A \u00e0 55A (74% de r\u00e9duction).<\/p>\n

3.1.1 Dynamique M\u00e9canisme De Compensation:<\/strong><\/h5>\n

SVG utilise des haut-d\u00e9bit puces DSP (par exemple, TI TMS320F28379D) pour \u00e9chantillonner des trois courants de phase \u00e0 10kHz, d\u00e9tecter n\u00e9gatif-s\u00e9quence de composants, et de g\u00e9n\u00e9rer de l'inverse de la r\u00e9mun\u00e9ration des courants. Par exemple, si la Phase actuelle est surcharg\u00e9, SVG injecte de la r\u00e9mun\u00e9ration des courants dans les Phases B et C \u00e0 l'\u00e9quilibre de la phase trois de vecteur somme.<\/p>\n

3.1.3 Mesures et Effets:<\/strong><\/h5>\n
(1) Supercondensateur de stockage de l'\u00e9nergie:Parall\u00e8le 48V\/165 F supercondensateur modules (par exemple, Maxwell BMOD0165) limite du bus continu les variations de tension de \u00b11.5% (solutions traditionnelles: \u00b15%).<\/strong><\/h6>\n

Signification:Un faible ratio affaiblit r\u00e9acteur de l'efficacit\u00e9, tandis qu'un ratio \u00e9lev\u00e9 peut provoquer la r\u00e9sonance.<\/p>\n
