With the digital scheme of both soft and hard work, the whole process simplified and full-time efficient distribution operation and maintenance experience is achieved

2023-12-08
With the increasingly complex structure of the electrical system and the increasing dispersion of the project, all links in the whole life cycle from design to construction, from operation to maintenance will face great challenges. How to ensure the safety and stability of the electrical system, efficient operation in the whole life cycle, and flexibility and scalability has become one of the most urgent problems to be solved for stable operation and development of various industries. Due to the low degree of digitization, the traditional distribution operation and maintenance mode does not have the ability to check the potential hazards of power supply and distribution system at any time and in time, which will not only increase the total holding cost of the project, but also seriously restrict the efficiency and safety of equipment operation in case of problems. As an expert in the field of energy management and power supply and distribution, Schneider Electric believes that the power supply and distribution system, as an important support for the construction and development of all walks of life, needs to make changes in all links of the whole cycle of design and selection, installation and commissioning, operation and maintenance, and even expansion and upgrading, so as to realize the whole process simplification, full-time efficiency, and finally create a convenient experience of the whole life cycle for users. 2 The product combination of software and hardware creates a convenient experience in the whole life cycle Throughout the whole life cycle of a project from design, construction to operation, maintenance and upgrading, OPEX expenditure in the operation, maintenance and upgrading stage often exceeds the design and construction cost of the project. Taking the operation and maintenance stage as an example, the operation and maintenance of a large number of equipment usually needs to be carried out in conjunction with manual patrol inspection, which requires the deployment of more manpower at the same time. However, in the face of tens of thousands to hundreds of thousands of sensor acquisition points, the manual mode based on operation and maintenance experience obviously no longer has advantages, which will also bring huge operation and maintenance costs and inefficient management. Therefore, how to make the operation and maintenance of distribution system more simple and efficient has become the focus of more projects. At the same time, with the penetration and extension of electrical system in more subdivided fields and the in-depth application of digital technology, customization needs began to emerge in large numbers. In the previous traditional distribution system, if the project needs to upgrade and deploy new optimization functions, products or systems, it is necessary to temporarily interrupt the work of some lines, or abandon the original system and directly connect to the new replacement scheme. The former will affect the continuity and stability of project operation; The latter means huge cost expenditure and waste of resources. Then, if the electrical product or system has certain scalability and can synchronously realize update optimization and uninterrupted operation, it can bring the best of both worlds. "Easy to use" software and hardware product portfolio is indispensable to maintain the reliable and stable operation of the whole distribution system in the process of operation, maintenance, expansion and upgrading for more than ten years or even decades after the project is delivered for use. Therefore, Schneider Electric can provide an intelligent software and hardware product portfolio in the operation stage, fully integrate the attributes of easy operation, strong interconnection and scalability, ensure the safe and reliable operation of power supply and distribution system at all times and for a long time, further help customers optimize the level and efficiency from operation and maintenance to expansion and upgrading, and finally realize pre-test maintenance and continuous power upgrading. Make the operation, maintenance and upgrading of the project simplified and efficient all the time. Help simple operation and efficient maintenance with "soft power" The rapid growth in the number of distribution equipment and people's higher requirements for distribution quality are bringing great challenges to the operation and maintenance of equipment. In the past, it was done by manual inspection, but with the advancement of the digital process, there are tens of thousands or even hundreds of thousands of digital products in the equipment. Obviously, the traditional mode will bring high operation and maintenance costs. Moreover, the traditional mode often does not have the ability to check the potential hazards of the power supply and distribution system at any time and in time. It can only be checked passively when problems occur, which will not only affect the normal operation of the power supply and distribution system, but also reduce the operation and maintenance efficiency. In order to help customers improve the operation and maintenance efficiency of distribution system. Schneider Electric has launched four kinds of software respectively applied to the scene of on-site maintenance of distribution equipment, monitoring of distribution system, asset management and upgrading and optimization of distribution facilities - ecostruxure power device (EPD) mobile application, facility expert Qianliyan operation and maintenance expert, digital logbook Qianliyan Zhilian log and go digital online mall.
