Problems solved by technology
[0005] However, the existing photovoltaic power station monitoring system is mainly provided by the inverter manufacturer with the equipment. It mainly starts from the inverter of the factory to monitor some parameters of the power station operation. It is difficult or impossible to directly control the operation status of the inverter, and it is also impossible to obtain The information and control of other equipment in the power station cannot meet the real-time monitoring requirements of the power grid dispatching system for the power station
In addition, large-scale power stations will use products from different manufacturers, and the products of these different manufacturers are not compatible with each other, resulting in "island" systems, unable to form a unified monitoring system

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] figure 1 It is a block diagram of an intelligent monitoring system based on a photovoltaic microgrid according to an embodiment of the present invention, and the following refers to figure 1 Now, the intelligent monitoring system of this embodiment will be described in detail.
[0026] The intelligent monitoring system of this embodiment adopts a three-level network architecture, which is respectively a local controller 1, a central controller 2 communicating with the local controller 1, and a local device connected to the local controller 1 (such as an inverter 3, an environment acquisition instrument 4, combiner box 5, sun patrol device 6 and camera 7, etc.). In addition, the intelligent monitoring system also includes a storage device 8 connected to th...

The invention discloses an intelligent monitoring system based on a photovoltaic microgrid. The system includes: at least one local controller, which controls various local devices connected to it in the photovoltaic microgrid and adapts to different communication protocols, and sends classified and collected information from the local devices, wherein the local control The controller has the function of expanding different communication protocols; the central controller receives the information sent by the local controller through Ethernet, and analyzes the information received from the local controller to remotely monitor and troubleshoot the photovoltaic microgrid diagnosis. The intelligent monitoring system of the present invention can remotely manage and monitor local devices using different communication protocols by using local controllers and central controllers that can expand multiple protocols, thereby avoiding the "island" system formed by each power station, A unified and complete real-time monitoring of the photovoltaic microgrid is realized.
Description
technical field [0001] The invention relates to the field of solar power generation, in particular to an intelligent monitoring system based on a photovoltaic microgrid. Background technique [0002] In today's world, fossil energy sources such as coal and oil are frequently running out, and the problem of environmental pollution is becoming increasingly serious. As the most potential renewable energy, solar energy is more and more favored by people because of its unlimited reserves, universality of existence, cleanness of utilization and practical economy. Vigorously developing the photovoltaic industry and actively developing solar energy have received unprecedented attention worldwide, and have become an important part of the sustainable development strategies of various countries. Photovoltaic industry, also known as solar cell industry, is an industry that uses solar-grade semiconductor electronic devices to absorb solar radiation and convert it into electrical energy....
