Digital Protection System of the Engine-Generator Based Microcontroller AT89C51

Abstract

This paper describes the design and implementation of the engine-generator protection circuit based microcontroller AT89C51, which is very popular and is used in a huge number of applications in professional systems and amateur projects. This digital electronic circuit shows further possibilities of improvements, and is employed as a device to protect the engine-generator from the fault type that may occur during operation of the generator such as over heat; oil alert; over speed; and over voltage that will damage the engine and exciter of the generator. It is also used to protect all devices that are connected to the generator. The engine–generator protection can be done by gathering data from the sensors attached to the microcontroller and some other electronic circuits.
