Problems solved by technology

Sending power limitation Since the carrier current will radiate electromagnetic waves to the space when it is transmitted on the power line, which will interfere with broadcasting and navigation services such as flight and navigation in this frequency band, so the sending power is limited.

Embodiment Construction

[0055] Below in conjunction with each embodiment, the technical solution of the present invention is clearly and completely set forth, but described embodiment is only the embodiment that the present invention is used for describing description and not all embodiments, based on these embodiments, this invention The solutions obtained by those skilled in the art without creative work all belong to the protection scope of the present invention.

[0056] A photovoltaic power generation system usually consists of a whole array of module panels and a power inverter. In a conventional scheme, a low-frequency isolation transformer is set between the inverter and the mains AC network to achieve electrical isolation between the grid-connected part and the panel array. Photovoltaic power generation systems usually also include power equipment such as combiner boxes. It can ensure that the power generation system is easy to cut off the circuit during maintenance and inspection, and reduc...

Abstract

The present invention mainly relates to a device and method for realizing data transmission, including a first device with a first processor and a second device with a second processor, the second device is connected with the first device for power transmission power line. An inductor closer to the first device than the second device is arranged on the power line, and a first switch is arranged between a DC voltage source and a certain terminal of the inductor, and then the first processor sends The main way for the carrier signal to the power line is to drive the first switch to switch between on and off at high frequency, thereby injecting a high-frequency pulse sequence carrying data information on the power line, regarded as a carrier signal.

Description

technical field [0001] The present invention mainly relates to the field of photovoltaic power generation. To be precise, a carrier communication mechanism is proposed in a power generation system involving photovoltaic cells and various types of power equipment, so as to realize information transmission between different equipment and avoid The communication carrier affects the normal power generation, and the power line carrier communication is realized under the premise of ensuring reliable power generation. Background technique [0002] In the field of new energy, photovoltaic power generation, a new energy source, has the advantages of cleanness, safety and reliability, low operating costs, simple daily maintenance, and on-site power generation, making photovoltaic power generation systems a new type of energy that is widely concerned and developed in countries around the world, especially in energy-deficient areas. The industry plays an indispensable role in solving th...
