INDUSTRIAL INTEGRATED ELECTRO-MECHANICAL FACTORY FOLK-LIFT RICE LOADING AND TRANSIENT CONTROL USING SYNCHRONOUS MACHINE DRIVE

Abstract

Industrial integrated electro-mechanical factory folk-lift rice loading and transient control using synchronous machine drive is presented. Electro-mechanical fork-lift was powered using electrical and mechanical processes for factory rice handling in the ware-house for better performance instead of the traditional internal combustion engine using rechargeable batteries due to the mechanical movement causing an electrical output transient and an emission of carbon dioxides and leakage of fluid on food meant for human consumption and constituting negative impact on rice used as food and on environmental system. Synchronous machine drive is an AC electrical motor that has a steady state, the rotation of the shaft that is synchronized with the frequency of the supply current, the rotation period is equal to an integer number of AC cycles. Experiment was carried out in standard research laboratory. The dc excitation of factory folk-lift was adjusted to ensure that and  is equal. The factory folk-lift synchronizing switch was closed and the current   was recorded as 0.3 ampere. Closing the factory folk-lift synchronizing switch when all the lights are dark, the stator current jumps quickly to 0.3 ampere and return to zero at the moment of the closure because the two-line voltage are not equal in phase with each other. Electrical and mechanical models of the factory fork-lift synchronous machine drive were obtained by solving synchronous machine equations governing electrical and mechanical using Runge-Kutta method. MATLAB/SIMULINK software with the Mathematical characteristics was used to model the factory folk-lift machines by setting its component transients to zero to obtain the complete reduced transients. Results presented graphically show that the factories fork-lift performance is very highly sensitive to load variation and recommended for factories fork-lift designers and fork-lift industrial operators.
