These interruptions include more current interference and more voltage disturbances, as well as paying attention to the ramping ratio. The on grid Solar Plant inverter grid device must be able to be protected from the effects caused by interruptions in the power grid because it is the main device in the on-grid Solar Plant system and is at the front of the Solar Plant installation interconnected directly to the medium voltage electrical system network. This paper emphasizes on the type and performance and completeness of on-grid Solar Power Plant protection system in Kupang with the aim of studying and investigating the completeness of the design of a security system that protects the grid device of the Solar Plant inverter. The method of analysis in the discussion of this thesis is to conduct literature studies and interviews and direct reviews to the location of the Solar Plant.} }
