PERANCANGAN KENDALI AUTOMATIC CHANGE OVER SWITCH GENSET 2500 VA BERBASIS MIKROKONTROLER (APLIKASI PLTA SINGKARAK)

Abstract

Automatic Change Over Switch (ACOS) is an automatic switching system or device that can move the main supply of emergency generators to supply emergency backup generator if the supply of the second network system using its own network (PLN) is trauble and the main generator can not generate electric power with good , ACOS can only be used at the power station which has two generators as a backup supply emergency.like in Singkarak hydropower plants  which has two generators as an emergency supply in case of disturbances in the system use their own network. But this time when generator I at the singkarak  Hydro power plants  can not operate the generator II can only be operated manually in  the control panel of the generator. In this study designed a control system ACOS in 2500 Va backup generator that will work to move the power supply to the generator II if there is a failure in the generators first start in 3 seconds. Furthermore ACOS control system design will be applied to the control circuit 700 KVA generators in singkarak hiydropowerplants
