Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] An off-grid photovoltaic power supply system for high-power loads on buoys, such as figure 1 As shown, including photovoltaic power generation group, energy storage battery group, power management group; among them,

[0041] The photovoltaic power generation group, such as Figure 5 with 6 As shown, it includes 46 photovoltaic modules. The photovoltaic modules adopt a double-layer disc structure. The top photovoltaic array is divided into 2 groups of 10 photovoltaic modules to generate 2-way photovoltaic arrays. The bottom photovoltaic array is connected in parallel by every 4 photovoltaic...

Abstract

The invention provides an off-net photovoltaic power supply system for a high-power load on buoy. Through a designed double-layer disk-shaped structure, the area of a photovoltaic array is increased, the photovoltaic electric energy production is increased, and the requirement of the high-power load is met; according to the mode that an independent photovoltaic power generation module is formed by a path of photovoltaic array, one to two storage batteries and a photovoltaic controller, when the power load is changed, the number of photovoltaic power generation modules is corresponding increased, and the requirements of different loads can be met; through a designed photovoltaic control circuit, the photovoltaic output current is increased, and the photovoltaic utilization rate is increased; through high-power Schottky rectifier diodes arranged inn discharging ports of the storage batteries, the discharging ends of the storage batteries are connected with a ring network in parallel and connected to the photovoltaic control circuit, the storage batteries can be connected in parallel conveniently, the ring network can be connected reliably, and convenience and reliability are improved.

Description

technical field [0001] The invention belongs to the field of buoy power supply systems, in particular to an off-grid photovoltaic power supply system used for high-power loads on buoys. Background technique [0002] At present, the buoys used in my country's lakes and oceans are mainly used for detection and detection purposes, and the buoys are equipped with electronic equipment such as sensors, measurement tests, and communications. In the case of less equipment, the power consumption is small, and the power supply is mostly combined with several photovoltaic modules installed on the surface of the buoy or on the top of the mast and lead-acid batteries to form an off-grid photovoltaic power generation system to supply power to the equipment to ensure the normal operation of electronic equipment. With the development and utilization of the ocean, buoys used for ocean and lake resource monitoring, rights protection target identification, etc. will be placed in the ocean envi...
