摘要： It is possible to increase power generation efficiency by optimally tracking sunlight while minimizing an installation space when compared to a facility of a two-axis rotation type by moving a PV panel in all directions by adjusting only slopes in an x-axis (horizontal axis) and a y-axis (vertical axis) of the PV panel so that the PV panel is perpendicular to incident sunlight without rotating the PV panel according to an azimuth.

摘要： Embodiments of the present disclosure include a retrofit auxiliary nacelle yaw position control system that enables advanced nacelle yaw position control of a wind turbine by comparing a desired nacelle yaw position signal with the actual nacelle yaw position and generating a virtual relative wind direction signal that is provided to the existing turbine control unit. This method and system enable implementation of wake steering, collective yaw optimization and dynamic yaw optimization of a collection of wind turbines referred to as a wind plant. Modification of the existing turbine control unit is not required, greatly simplifying the implementation process of advanced yaw control strategies on existing wind plants.

摘要： Driving-evaluation-apparatus evaluating driving-status of driver driving mobile-body, includes: microprocessor and memory. The microprocessor functions as: information-acquisition-unit acquiring location/travel-speed-information of mobile-body based on GPS-signals received by driver's mobile-terminal; entry-direction-calculation-unit calculating entry-direction in which mobile-body enters determination-area based on location/travel-speed-information; entry-direction-determination-unit determining whether angle formed by entry-direction and predetermined-reference-entry-direction is predetermined-angle or smaller; state-determination-unit determining whether there is stop/deceleration-state in which travel-speed is predetermined-travel-speed or lower within time-period from time-point when mobile-body enters determination-area to time-point when mobile-body exits determination-area based on location/travel-speed-information when angle is predetermined-angle or smaller; and driving-evaluation-unit evaluating driver's driving-status in determination-area based on determination-result. The determination-area is area inside determination-circle centered on reference-point predetermined-distance before the predetermined-location and having predetermined-radius. The angle is angle formed by: straight-line along the reference-entry-direction and passing through the reference-point; and straight-line connecting plot representing location of the mobile-body before entering inside the determination-circle based on location/travel-speed-information and the reference-point.

摘要： A material moving machine includes a chassis, a dual-sensor position sensor system including a master and a slave, and a controller. The master and the slave are each configured to generate independent position signals representing a machine position. The controller is programmed to determine whether the machine is tramming, determine whether the master and the slave are operational, determine a center of rotation (COR) of the chassis when the machine is not tramming, and determine heading(s) based on a pair selected from the COR, an operational master, and an operational slave. The controller is further programmed to determine a prioritized heading based on at least one of the operational master and the operational slave and based on an order of priority that ranks the heading(s), use the prioritized heading to generate the machine heading when the machine is not tramming, and operate the machine based on the machine heading.
