Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0049] A distributed power system, such as a photovoltaic power generation system or an energy storage system, mainly includes: a main controller, multiple power devices, and at least one slave device. When multiple distributed power systems are arranged in a similar area, the method for suppressing communication crosstalk of the distributed power system provided by the embodiment of the present invention can be used.

Abstract

The invention provides a distributed power supply system and communication crosstalk suppression method thereof, which are applied in the technical field of communication control. In the method, the main controller sends the first command to the slave device in the form of broadcast through wireless communication or power line carrier communication; and then by The slave device analyzes the first instruction; the slave device internally stores the first characteristic code, and only when the slave device judges that the analysis result includes the first characteristic code, the slave device will execute the first instruction, so as to realize the corresponding power supply device The operation control, that is, the distinction of the instructions of the main controller in different distributed power supply systems through different implementations of the first feature code, thereby avoiding the problem of communication crosstalk between different distributed power supply systems in the prior art.

Description

technical field [0001] The invention relates to the technical field of communication control, in particular to a distributed power supply system and a communication crosstalk suppression method thereof. Background technique [0002] A distributed power system refers to a system with multiple power sources, such as a photovoltaic power generation system with multiple photovoltaic modules and photovoltaic inverters, or an energy storage system with multiple batteries and power control systems. Multiple devices in a distributed power system (such as power supply equipment, monitoring equipment, protection equipment, etc.) are usually under the centralized control of a main controller, for example, in a photovoltaic power generation system with multiple photovoltaic inverters, all photovoltaic inverters The controllers are all controlled by a main controller (sometimes called station controller) to realize switching on and off, active and reactive power scheduling, etc. In view...
