<\/p>\n
<\/p>\n
Bir g\u00fcne\u015f enerji sistemi (GES) inverter arac\u0131l\u0131\u011f\u0131yla do\u011fru ak\u0131m\u0131 (DC) alternatif ak\u0131ma (AC) \u00e7evirir. Bu enerji daha sonra \u015febekeye aktar\u0131l\u0131r.<\/p>\n
Ancak inverterin \u015febekeye enerji verebilmesi i\u00e7in iki sistemin tam senkron olmas\u0131 gerekir.<\/p>\n
\u0130\u015fte bu senkronizasyonu izleyen ve koruyan cihaz \u015febeke izleme r\u00f6lesidir.<\/p>\n
<\/p>\n
\u015eebeke izleme r\u00f6lesi, inverterin \u00e7\u0131k\u0131\u015f\u0131n\u0131 s\u00fcrekli kontrol ederek \u015fu parametreleri \u00f6l\u00e7er:<\/p>\n

Gerilim (Voltage)<\/p>\n

Frekans (Frequency)<\/p>\n

Faz s\u0131ras\u0131 ve a\u00e7\u0131s\u0131 (Phase sequence & angle)<\/p>\n

Bu de\u011ferlerden biri s\u0131n\u0131r d\u0131\u015f\u0131na \u00e7\u0131kt\u0131\u011f\u0131nda, r\u00f6le inverterin \u015febekeye enerji vermesini otomatik olarak keser.<\/p>\n
<\/p>\n
<\/p>\n
\u015eebeke izleme r\u00f6lesi, inverter ile \u015febeke aras\u0131ndaki ba\u011flant\u0131 noktas\u0131nda bulunur.<\/p>\n

\u015eebeke ile inverter aras\u0131ndaki enerji ak\u0131\u015f\u0131 kesilir.<\/p>\n
<\/p>\n
Sistem, g\u00fcvenli duruma ge\u00e7er.<\/p>\n
<\/p>\n
Bu i\u015flem milisaniyeler i\u00e7inde ger\u00e7ekle\u015fir ve hem inverteri hem de \u015febeke ekipmanlar\u0131n\u0131 korur.<\/p>\n
<\/p>\n
<\/p>\n
GES sistemlerinde en tehlikeli durumlardan biri ada modu (islanding) olarak adland\u0131r\u0131l\u0131r.<\/p>\n
Bu, \u015febeke enerjisinin kesildi\u011fi h\u00e2lde inverterin enerji vermeye devam etmesidir.<\/p>\n
<\/p>\n
Bu durumda:<\/p>\n
<\/p>\n
\u015eebeke hatt\u0131nda \u00e7al\u0131\u015fan teknisyenler elektrik \u00e7arpmas\u0131 riski alt\u0131ndad\u0131r.<\/p>\n

<\/p>\n
\u015eebeke izleme r\u00f6lesi, bu durumu alg\u0131layarak inverteri devre d\u0131\u015f\u0131 b\u0131rak\u0131r ve ada modunun olu\u015fmas\u0131n\u0131 engeller.<\/p>\n
<\/p>\n
<\/p>\n
T\u00fcrkiye\u2019deki TEDA\u015e y\u00f6netmelikleri ve uluslararas\u0131 standartlar (VDE-AR-N 4105, EN 50438) GES panolar\u0131nda \u015febeke izleme r\u00f6lesi kullan\u0131lmas\u0131n\u0131 zorunlu k\u0131lar.<\/p>\n

Bu r\u00f6leler \u015fu i\u015flevleri sa\u011flar:<\/p>\n

Bu \u00f6zellikler sayesinde GES sistemi hem yasal hem de teknik gereklilikleri kar\u015f\u0131lar.<\/p>\n

Bir GES panosunda inverter \u00e7\u0131k\u0131\u015f\u0131 genellikle kompakt \u015falter (MCCB) \u00fczerinden \u015febekeye ba\u011flan\u0131r.<\/p>\n
Ancak MCCB sadece a\u015f\u0131r\u0131 ak\u0131m korumas\u0131 sa\u011flar \u2014 \u015febeke senkronizasyonunu izleyemez.<\/p>\n
<\/p>\n
Bu nedenle MCCB \u00f6ncesine bir \u015febeke izleme r\u00f6lesi ba\u011flan\u0131r.<\/p>\n
R\u00f6le, \u015febeke parametrelerini izler ve gerilim, frekans ya da faz de\u011ferlerinde bir anormallik tespit etti\u011finde MCCB\u2019yi a\u00e7t\u0131rarak inverteri devre d\u0131\u015f\u0131 b\u0131rak\u0131r.<\/p>\n

Bu uygulama, hem \u015febeke g\u00fcvenli\u011fi hem de inverter \u00f6mr\u00fc a\u00e7\u0131s\u0131ndan kritik \u00f6neme sahiptir.<\/p>\n
