Embodiment 1

[0039] This embodiment provides a distributed power supply power quality monitoring device, for example, the device can be installed at the grid-connected point of the distributed power supply, and the power required by the device can be provided by external network lines, such as figure 1 As shown, the device 10 includes:

[0040] The monitoring module 1 is used for real-time monitoring and recording the working status and power quality information of the distributed power at the grid-connected point;

[0041] The 4G communication module 2 is used to establish communication connections with the superior dispatching center 20 and the mobile device 30 respectively by adopting 4G technology.

[0042] The above-mentioned distributed power supply power quality monitoring device uses a 4G communication module to use the distributed power quality monitoring device based on 4G technology to monitor the power quality information at the access point of the distributed power supply, and...

Embodiment 2

[0052] This embodiment provides a method for monitoring the power quality of distributed power sources, for example, it can be applied to the device for monitoring power quality of distributed power sources in the above-mentioned embodiment 1. The method includes the following steps:

[0053] S1. The monitoring module monitors and records the working status and power quality information of the distributed power supply at the grid-connected point in real time;

[0054] S2. The monitoring module sends a message including the working status and power quality information of the distributed power supply to the mobile device after receiving the message sent by the mobile device through the 4G communication module, including a request to view the working status and power quality information of the distributed power supply .

[0055] Preferably, the method also includes the steps of:

[0056] S3. The monitoring module receives the dispatching instruction sent by the superior dispatch...

Abstract

The invention discloses a distributed power supply power quality monitoring device and method, wherein the device includes: a monitoring module for real-time monitoring and recording the working status and power quality information of the distributed power supply at the grid-connected point; a 4G communication module for The 4G technology is used to establish communication connections with the superior dispatching center and mobile devices. The invention can realize the real-time monitoring of the power quality at the access point of the distributed power supply, and at the same time interact with the superior dispatching center through the 4G communication module, and can display information such as the working status of the distributed power supply and operation instructions on the mobile device of the user.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a distributed power supply power quality monitoring device and method. Background technique [0002] In recent years, with the rapid development of my country's economy, the contradiction between energy depletion and environmental protection has been escalating. It is urgent to build a reliable, economical and environmentally friendly strong smart grid. Distributed power supply is a new energy-saving and environmentally friendly A large number of grid-connected power generation devices is the inevitable trend of smart grid engineering construction. Although the distributed power output is intermittent and random, and the use of power electronic equipment to connect to the grid will inevitably have a great impact on the power quality of the grid, but because the distributed power grid connection point is remote, scattered, and the environment is complex, currently its Power quality mo...
