International Classification:

F24J 2/38

Abstract:

A network topology for powering and communicating with groups of heliostats in a concentrated solar power plant. Heliostats are arranged in rows and wired together with inter-drive cables that distribute power and data from a field electrical system and plant network. Data is transmitted to and from heliostat drive control boards via network switches connected to intelligent power distribution units. Power is transmitted from battery banks to said intelligent power distribution units. Communication interface modules supply a connection between intelligent power distribution units and the heliostat control boards of non-adjacent heliostat rows to create communication and data loops having improved redundancy and robustness in the event of single point component failures.

Abstract:

A drive assembly for a heliostat and a method of determining the drive's home position are described. The drive assembly comprises at least one mechanical hard stop for impeding the motion of an output gear of at least one gear transmission driven by a motor. Each hard stop may be built into the housing of a gear transmission or may be made integral with an output gear. The method for determining the drive assembly's home position comprises the steps of iteratively actuating an output gear towards, and then away from, a hard stop feature while monitoring the input torque of the driving motor. When the motor input torque is registered to be higher than a predetermined trip torque, the stepper motor is commanded to stop and the home position of the drive assembly is determined.
