Solar energy wind energy wave energy power generation controller and system

Abstract

The invention relates to a solar energy wind energy wave energy power generation controller and system. The power generation controller comprises at least one coil connected to the positive and negative poles of a power generating device; a magnetic induction switch disposed in the coil, connected in series to the power supply line, for supplying power to a load, of the power generating device, and configured to control the on / off state of the load power supply by being turned on or off under the effect of a magnetic field generated after the coil is energized. After the power generation, allthe current flows through the coil and generates a magnetic field. The strength of the magnetic field is proportional to the magnitude of the current. The magnetic induction switch in the coil controls the on / off state of the load power supply by being turned on or off under the effect of the magnetic field generated after the coil is energized, thereby achieving dual automatic control of the loadopening and closing and the real-time distribution of the power generation. The power generation controller does not require a battery and a peripheral circuit, is simple in structure, small in size,low in cost, and high in user satisfaction. On this basis, the controller optimizes the system, efficiently uses the electric energy, and has a practical promotion value.

Description

technical field [0001] The invention relates to the technical field of solar wind energy wave energy power generation controllers, in particular to a solar wind energy wave energy power generation controller and a system. Background technique [0002] Most of the energy needed by human beings comes directly or indirectly from the sun. According to the report of the National Energy Administration, the installed capacity of photovoltaic power generation in China ranked first in the world by the end of 2016. Due to the instability of solar energy in time and space, controllers are essential in solar photovoltaic power generation systems. [0003] In the prior art, the disadvantages of solar power generation controllers are: [0004] 1. The solar power generation controller has more components, higher cost, higher energy consumption, and lower relative reliability. Because of this shortcoming, there is not an ideal controller for small and micro solar panels (sheets) now. For...

Problems solved by technology

[0004] 1. The solar power generation controller has more components, higher cost, higher energy consumption, and lower relative reliability

Due to this shortcoming, there is no ideal controller for small and micro solar panels (sheets)

For example, using a solar cell that costs a few yuan to power a small LED light may not be bright enough on a rainy day, but the strong current at noon on a sunny day burns it out.

For example, the controller produced by the existing technology, firstly, the power and resistance of the controller itself will consume the tiny current, and secondly, the cost is high and the volume is large

[0005] 2. At present, the most common way to use solar photovoltaic power generation is that the solar panel charges the battery through the controller, and the battery supplies power to the electrical equipment. When the battery is fully charged, the power supply circuit of the solar panel is cut off. Although the stability is high, but The disadvantages are: firstly, the electric energy of the solar panel is wasted; secondly, the frequent charge and discharge of the battery reduces the efficiency of electric energy usage and shortens the service life of the battery; thirdly, the battery of the existing solar power generation system is generally indispensable, but the energy density is low, The cost is high and has adverse effects on the environment; Fourth, in fields such as national defense and aerospace that require high reliability or extreme environmental conditions, sometimes it is not suitable to use batteries, or the batteries affect the overall service life of the product, or the electronic components in ordinary controllers unable to work properly

[0006] Wind energy and wave energy, as a conversion form of solar energy, also have similar problems. The electric energy cannot be effectively used when the power generation is low or too high, and the control is more complicated. At present, there are few small-scale, low-cost and high-reliability power generation control systems on the market. have appeared, and in the plains, coastal areas and mountainous areas, this kind of new energy reserves are very rich
