Kinematic modelling of the tracking system for parabolic trough collector

摘要

Sun is the main source of renewable energy. Sun energy can be transformed into thermal energy or electric energy by using solar collectors of trough type. These collectors are provided with mono - axial tracking systems. The paper presents the kinematic modeling of a tracking system with linkages driven by three linear actuators. The following independent parameters are considered to determine the actuators strokes: the rotation angle of the trough collector, the transmission angle and the constant stroke of one actuator.
