Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, in t...

Abstract

The invention discloses a photovoltaic phase-sequence-free power generation system which comprises a solar cell panel, a capacitor cabinet, a three-phase generator and a low-voltage cabinet which are electrically connected in sequence, wherein the three-phase generator and the capacitor cabinet are connected in a phase-sequence-free mode, a power distribution element is arranged in the low-voltage cabinet, the power distribution element is provided with an input end and an output end. The input end is connected with the three-phase generator, the output end is connected with a voltage monitor and an output cable, the output cable is provided with a control switch, and the voltage monitor is electrically connected with the control switch. Compared with a traditional photovoltaic power generation system, the photovoltaic phase-sequence-free power generation system has the advantages that an inverter is omitted, so that electric energy in the capacitor cabinet is output to the three-phase generator without passing through the inverter and then is directly output to civil two-phase power through the low-voltage cabinet, and loss of the electric energy is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic non-phase sequence power generation system. Background technique [0002] A photovoltaic power generation system is a device that converts solar energy into electrical energy. [0003] Existing photovoltaic power generation systems usually include an inverter to convert direct current into alternating current, but the inverter will cause loss of electric energy. Contents of the invention [0004] The main purpose of the present invention is to provide a photovoltaic non-phase-sequence power generation system, which aims to solve the problem that the inverter in the photovoltaic power generation system will cause a large amount of power loss. [0005] To achieve the above object, the present invention proposes. [0006] In the technical solution of the present invention, the photovoltaic non-phase-sequence power generation system has fewer ...
