Embodiment Construction

[0044] 1). The sun tracking system is composed of optical tracking detector, dual-axis mechanical tracking and positioning system, clock circuit, single-chip microcomputer control system and remote monitoring system.

[0045]Among them, the light tracking detector is mainly composed of a photosensitive element, a T-shaped light-shielding plate, an element plate and a toughened glass cover. The T-shaped light barrier divides the element board into 3 areas, and each area houses a photosensitive element. The output of the 3 photosensitive elements passes through the discrimination circuit to separate 4 output signals. When the light is irradiated by the vertical T-shaped light barrier, the light intensity on the photosensitive elements in each area is equal, and their output signals are also equal. At this time, the output signals of the four channels separated are all zero, indicating that the center position of the sensor is aligned. sun. When the light deviates from the vert...

Abstract

The invention provides a maximum power tracking control method, relating to the technical field of solar energy power generating. The method comprises the following steps: a solar tracking system sends out corresponding control signals according to the detecting results of an optical tracking detector, controls running of the mechanical part of a tracking and positioning system of biaxial machinery so that sunlight always vertically irradiates a solar panel; meanwhile, the detecting results of the optical tracking detector are fed back to a maximum power point tracking controller and the maximum power point is tracked by combining the characteristics of the solar panel. By the method, conversion efficiency of the system is improved on the basis of improving the utilization factor of solar radiation energy and cost of the system can be indirectly lowered; closed-loop control of the grid-connected current can be realized so that the output current of inverters is synchronous with the line voltage (the power factor is 1), thereby avoiding the impact of the grid-connected current on power networks; system dynamics has the obvious characteristics of fast response speed, safe and reliable running, no pollution to the line voltage and low harmonic distortion of the grid-connected current, etc.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a maximum power tracking control method for solar photovoltaic power generation. Background technique [0002] In a photovoltaic power generation system, to improve the overall efficiency of the system, an important way is to adjust the operating point of the solar cell in real time so that it always works near the maximum power point. This process is called maximum power point tracking (Maximum Power Point Tracking). Point Tracking, MPPT). Another important way is to track the sun in real time, so that the solar panels are always perpendicular to the sunlight, and improve the overall conversion efficiency by improving the utilization of sunlight. [0003] Existing photovoltaic power generation systems generally only adopt one of the above-mentioned approaches, and do not organically combine the above-mentioned two approaches, which results in the ina...
