Description

technical field

[0001] The invention belongs to the field of monitoring, diagnosis and operation and maintenance of the whole life cycle of a photovoltaic power station, and is specifically a system for collecting main performance parameters of a solar power station and intelligently processing the parameters. Background technique

[0002] Solar photovoltaic power station is a new green and environment-friendly power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Usually solar photovoltaic power plants include solar panel arrays, combiner boxes, low-voltage power distribution cabinets, grid-connected photovoltaic inverters, AC power distribution cabinets, transformers and other components to achieve grid-connected power generation in a straight line.

[0003] In order to ensure the normal operation of the solar photovoltaic power station, a monitoring system is used ...

Examples

Embodiment 1

[0038] A photovoltaic power station operation and maintenance system, including a local server, a centralized control center server, a data acquisition module, a communication module, a data storage module, a monitoring module, and a fault alarm module;

[0039] Wherein, the local server is provided with a first communication module, the local server is connected with the data acquisition module, and the data acquisition module is used to collect the power generation data of each photovoltaic power station in the system, and sends the data information to the centralized control center through the first communication module on the server;

[0040] The centralized control center server is connected to the monitoring module, the fault alarm module, the video module, the second communication module and the central data storage module;

[0041] The monitoring module controls the operation of each photovoltaic power station through the data in the data storage module of the centrali...

Embodiment 2

[0049] like figure 2 As shown, on the basis of Embodiment 1, the photovoltaic power plant operation and maintenance system also includes a video monitoring module composed of several video devices. The video monitoring module is connected to the centralized control center server and divides the photovoltaic power plant into several areas. The video equipment is distributed in each area, and the number of the area is matched with the number of the video equipment and stored in the database, so that the video information of the corresponding area can be quickly called out from the video monitoring module.

Embodiment 3

[0051] like image 3 As shown, on the basis of Embodiment 2, the photovoltaic power station operation and maintenance system also includes an asset management module and an operation and maintenance management module. The asset management module is used to record the attributes and information of each photovoltaic power station asset equipment and generate a statistical table , so that the operation and maintenance management module can uniformly allocate the assets of each photovoltaic power station. The operation and maintenance management module provides remote control functions to realize unattended on-site; the asset management module also provides scientific and credible information for the financing, transfer and bondization of photovoltaic power plants.

[0052] The main function of the operation and maintenance management module is to solve the problem through remote direct control or issue a work order to notify the on-site personnel to deal with the problem after th...
