A substation refers to a place in the power system that converts voltage and current, receives electric energy, and distributes electric energy.
With the continuous progress of science and technology, the power industry is gradually realizing the transformation of intelligence and automation, and the digital substation is an important embodiment of this transformation. It is highly intelligent, energy-efficient, safe and reliable, which is in line with the development trend of the power industry to transform to a clean, intelligent and efficient direction.
Yijiawei 500kV substation 3D digitization project case.
Project introduction: This project is to carry out 3D scanning and collection of the entire plant area of the 500kV substation, including the outdoor equipment of the substation, the fire pump room and the small room areaAnd through the 3D model of the data topology substation obtained by 3D scanning, the basic model data is provided for the digitization of the substation.
Advantages of 3D scanning technology to collect 3D data of substations.
It is an industry-recognized collection method to collect 3D data of substation through 3D laser scanning technology. The advantages are obvious:
1.High precision and high efficiency: 3D scanning technology can quickly and accurately obtain the spatial location information of various facilities and equipment in substations. Compared with traditional measurement methods, the accuracy is higher and the efficiency is greatly improved.
2.Non-contact measurement: 3D scanning technology adopts non-contact measurement method, which avoids the danger of traditional manual live operation, and also reduces the influence of human factors on the measurement results, making the data results more objective and real.
3.Obtain rich data results: 3D scanning technology can simultaneously capture real images of the survey area, providing real-time, reliable on-site information for staff. In addition, post-modeling allows for quick analysis of overtight or uneven cables.
4.Increased work safety: Thanks to the non-contact measurement, workers do not need to come into direct contact with high-pressure equipment, which greatly improves work safety.
3D digital solution for Yijiawei substation.
Yijiawei has undertaken substation projects for many times, and has rich experience in data collection and model making of substations, and has reasonable on-site collection and station layout to ensure that there is no omission of data. The Leica RTC 360 laser scanner collects data from the substation equipment and environment to obtain the 3D point cloud data of the substation, and takes high-definition photos of the substation nameplate and other information through the camera for model mapping.
Substation 3D scanning point cloud data processing.
After the original substation data is collected by the 3D laser scanner, the noise on the point cloud data is removed by the corresponding software, and the data of multiple stations are spliced together to obtain the complete 3D point cloud data of the substation.
3D point cloud data modeling of substation.
Through professional modeling software, make a three-dimensional true color model of the substation. The three-dimensional model can intuitively reflect the appearance of the substation equipment and realize the three-dimensional visualization of the substation.
The use of a 3D model of a substation.
1.The 3D model can provide detailed information and characteristics of substation facilities and equipment, so that managers and technicians can understand the situation of the substation more intuitively. This can greatly improve management efficiency and reduce the possibility of misunderstanding and misoperation.
2.The 3D model can be used for asset management of substations. Through the model, it is more convenient to count and manage the assets of the whole site, and improve the efficiency and accuracy of asset management.
3.The 3D model can also be used for the alteration and retrofitting of substations. Through the 3D model, possible problems can be foreseen in the design and planning stage, so as to make adjustments in advance and avoid problems in the actual construction. This not only saves costs, but also improves the efficiency of retrofits.
4.The 3D model can also be used for virtual operation and maintenance of substations and visual data management. For example, the digital signal output by the sensor of the device can be used to capture and process data on the platform to realize the display and interactive management of dynamic data. This can help implement intelligent detection and improve the efficiency and security of O&M.
