Substations tau tshwm sim txij li thaum tsim thawj lub zog muaj tseeb. Raws li ib feem tseem ceeb ntawm lub zog hluav taws xob, lawv tau hloov kho nrog rau ntau tshaj 100 xyoo. Nyob rau hauv lub xyoo pua no, substations tau hloov pauv tseem ceeb hauv qhov chaw tsim kho, qib voltage, thiab khoom siv.
Cov chaw tsim kho substation tau hloov zuj zus los ntawm qhov qub qhib- huab cua, sab nraum zoov substations mus rau sab hauv tsev thiab qee qhov chaw hauv av, txo cov hneev taw ntawm substations piv rau qhov qub qhib - huab cua, sab nraum zoov substations.
Hais txog cov qib voltage, kev tsim hluav taws xob thev naus laus zis tau hloov pauv los ntawm cov qauv sib txuas me me nrog cov xov tooj me me ntawm 110kV thiab 220kV substations ua haujlwm hub substations thiab 35kV raws li cov chaw nres tsheb hauv lub davhlau ya nyob twg rau cov qauv sib kis loj dua nrog ultra-high voltage 1000kV thiab 500kV substations thiab 200kV substations 110kV substations pab raws li qhov chaw nres tsheb substations.
Hais txog cov khoom siv hluav taws xob, cov cuab yeej tseem ceeb tau hloov kho los ntawm cov cuab yeej qhib sab nraum zoov mus rau tag nrho cov khoom siv hluav taws xob sib xyaw ua ke (GIS) thiab ib nrab -cov khoom siv hluav taws xob sib txuas ua ke (HGIS); Cov khoom siv thib ob tau hloov zuj zus los ntawm cov transistor thaum ntxov thiab kev tiv thaiv kev tiv thaiv rau microcomputer.
