Solar photovoltaic industry will occupy an important position in the future world energy consumption, which will not only replace some conventional energy sources, but also become the main body of world energy supply. The future energy internet will be based on the existing power grid and realize the two-way flow of energy and information through advanced power electronics technology and information technology.
With the increase of the proportion of fluctuating power sources such as photovoltaic power generation, the power supply side is required to have greater regulation ability, distributed energy storage will be popularized, and active distribution network will emerge as the times require. Solar power generation is a new application form of solar power generation, which complements other renewable energy sources and energy storage, forming a microgrid that can be connected to the power grid and run in isolation from the load. It is not only suitable for power supply in remote farming and pastoral areas and islands, but also suitable for networked operation of controllable generator sets in power grid.
With the continuous development of photovoltaic industry, various industries also use their own advantages to carry out applications, such as photovoltaic agriculture, photovoltaic fisheries, photovoltaic pumps, photovoltaic parks, photovoltaic charging piles, photovoltaic intelligent street lamps and so on.
Expounding the future development mode of photovoltaic industry from the perspective of digitalization;
Real-time monitoring of operation status in the process of large-scale outdoor photovoltaic power generation is realized, and information such as power station load and equipment management and control is interconnected. Digital pairing of photovoltaic power plants in different environments. Reduce the manual operation cost and harm of outdoor photovoltaic power station operation and maintenance control, and realize a new situation of unattended outdoor photovoltaic power station.
Through live shooting, satellite images, etc. Set up the scene, manually place the heliostat model, and distribute the heliostat from the power tower to truly restore the distribution effect of the installed machine. The scene looks like a huge sunflower from top to bottom, the power tower is the center of the scene, and the mirror is the medium that reflects sunlight. The power generation tower is equivalent to a large heat absorber, which receives the heat refracted by hundreds of heliostats at the same time at one time, and then exchanges heat energy to promote the turbine engine to generate electricity. Through the rendering function of the robot engine, the heat absorption effect of the power tower is truly restored.
Information monitoring of thermal power plant
Click on the power tower model in the interactive scene, and the relevant information of the power tower pops up in the form of a two-dimensional pop-up window, which is linked with the background data to access the real data, show the power generation situation of the power tower and the running state of the engine, and realize real-time monitoring and management.
Information monitoring of photovoltaic power station
The data of junction boxes in each array (including bus voltage, cabinet temperature and current) can be monitored through the docking data interface. When an alarm occurs, the model can be displayed by flashing red, which is convenient for the operation and maintenance personnel to quickly locate and troubleshoot the problem. You can check the related indicators of equipment in real time without leaving home, and realize data analysis by combining algorithms. When abnormal data changes in a short period of time, you can give an alarm in advance to remind relevant personnel to make decisions in time.
At the same time, access the relevant data of box transformer (including oil temperature, voltage and current of box transformer), inverter (including today's power generation, total active power, total reactive power, total power factor and inverter efficiency) and booster station to comprehensively monitor the operation status of the power station. Because the scene is large, the viewing angle of clicking the device model is enlarged, and the related information of the device can be viewed more intuitively.
In the past, the concept of energy saving and carbon reduction should be changed to more use of renewable energy. Many solar photovoltaic companies have been developing an integrated system of light storage and charging, which can be organically combined with the use of office buildings, carports, electric vehicles and other technology companies such as the Internet. Science and technology enterprises can also participate in the construction, operation, management and maintenance of carbon-neutral digital platforms and Internet of Things equipment.
To strengthen the policy support for the new energy economy strategy, the relevant national ministries and commissions launched the solar roof plan. Solar roof is to install a solar power generation device at the top of the house, and use solar photovoltaic technology to generate electricity in urban and rural building areas to achieve the purpose of energy saving and emission reduction.
Using lightweight three-dimensional modeling technology, 1: 1 high simulation restores the photovoltaic industrial park. Three-dimensional scene superimposes BIM building data into the map scene to realize the joint display of BIM and GIS.
The 2D data panel digitally displays the operation, safety equipment and surrounding dynamic environment of each area in the park. It also supports rendering oblique photography model files in 3D Tiles format. Hightopo implements an interactive Web 3D scene, which can be scaled, translated and rotated, and all devices in the scene can respond to interactive events.
