ABSTRACT

A solar powered hybrid elevator system is designed to operate on solar power with grid support. The elevator’s power unit is the collection of components that raise and lower the elevator, often known as the drive machine. In remote locations, the gearless elevator drive machines are DC-powered electric motors with low speed and high torque. Separately excited direct current motors are preferred in most adjustable speed drives because of their controllability and precision. A four quadrant DC to DC converter can regulate the speed of the DC motor from 0 to rated speed in both forward and reverse directions. It may also be switched between motoring and regenerative modes. The solar panels’ energy is collected through MPPT control and utilized right away for energizing the four quadrants DC-DC converter system. The proposed elevator control is designed to run in the combination of solar and grid supply, depending on the traffic and intensity. Dedicated open-loop proportional-integral control is employed for regulating the armature voltage to achieve the desired speed. In this chapter, the separately excited DC motor drive-based solar-powered elevator system is modeled and realized in MATLAB/Simulink platform. Further, the drive system is analyzed with a real-time elevator’s load profile.
