Distributed Power Generation System and Its Remote Monitoring System

Abstract

The invention provides a remote monitoring system for a distributed power generation system, the power generation system includes one or more DC power supplies and matching inverters, communicators and databases; the inverters are connected to bus cables; one end of the communicators It is connected to the bus cable, and the other end is connected to the database through the Internet; the remote monitoring system includes a monitoring terminal, a local computer and a mobile application device; the mobile application device and the communicator are connected through a local area wireless communication network, and through a wide area mobile communication network Connect to the database through the Internet; the monitoring terminal is also connected to the database through the Internet to obtain monitoring data; the local computer is connected to the communicator to make related settings on the communicator and display relevant information in the communicator. The invention establishes a two-way transmission and information display mechanism between the communicator and the database, can be connected without a network port device, and can accept remote monitoring. In addition, the information in the database can be sent back to the communicator and displayed, which is convenient for customers to use.

Description

technical field [0001] The invention relates to the technical field of monitoring of power generation systems, in particular, the invention relates to a distributed power generation system and a remote monitoring system thereof. Background technique [0002] In the existing distributed power generation system, the power generation unit (DC power supply and inverter) is connected to the communicator to transmit data, and the communicator is connected to the Internet to transmit the data to the database, thereby providing monitoring account usage and realizing remote monitor. [0003] figure 1 It is a schematic diagram of a module connected to a distributed power generation system and its monitoring terminal in the prior art. Such as figure 1 As shown, the power generation system includes multiple DC power sources 101 and their associated inverters 102 , network port equipment 103 , communicator 105 , database 107 and local computer 109 . Wherein, each inverter 102 is conn...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing technology requires the communicator 105 to connect to the Internet 106 through the network port device 103, otherwise it cannot have such a remote monitoring function, and some customers do not have the network port device 103, so this function cannot be realized

In addition, the account information and other data of the monitoring terminal 108 are only stored in the database 107, and other devices such as the communicator 105 do not have the account information of the monitoring terminal 108, which is inconvenient for customers to use, and it will be troublesome if customers forget it.

In addition, in the prior art, the communicator 105 transmits the operating data to the database 107 in one direction, without reversely obtaining and displaying data information from the database 107, especially when the communicator 105 is not connected to the Internet 106
