　　Analyze each link from top to bottom. In terms of data collection, it is necessary to use remote terminals to obtain various required indicators, such as harmonics, deviations, etc. This is the basis for subsequent steps and places strict requirements on the accuracy of monitoring. Next, two aspects of analysis will be conducted. If each indicator is analyzed one by one, it can be called a one-way indicator evaluation process; In addition, each indicator * ultimately needs to form a whole, so comprehensive evaluation is also essential, which is the comprehensive evaluation process. *Finally, by integrating the two dimensions of evaluation, a more comprehensive evaluation result can be obtained, which is the evaluation conclusion stage. *Finally, based on the conclusions drawn and taking into account the actual situation of the rail transit system, corresponding strategies are formulated to provide transportation support.

　　The user side consumes 80% of the electricity in the entire power grid, and intelligent electricity management on the user side is of great significance for reliable, safe, and energy-saving electricity consumption. Build an intelligent electricity service system, comprehensively promote user side intelligent instruments, intelligent electricity management terminals and other equipment electricity management solutions, and achieve a two-way benign interaction between the power grid and users. The research content urgently needed to be solved on the user side mainly includes advanced meters, intelligent buildings, intelligent appliances, value-added services, customer electricity management systems, demand side management, and other topics.

　　The power management solution subdivides and statistically analyzes the electricity consumption of the user end, and displays the usage and consumption of each sub item of electricity to management personnel or decision-makers through intuitive data and charts. This facilitates the identification of high energy consumption points or unreasonable energy consumption habits, effectively saving energy and providing accurate data support for users to further energy-saving renovations or equipment upgrades.

　　(1) Lack of awareness of energy conservation and electricity saving.

　　University faculty, staff, and students are direct users of electrical energy, and their awareness of energy conservation directly determines the level of energy conservation awareness in the entire school, while also serving as a model and guide for the overall social atmosphere. But it is an undeniable fact that some teachers and students have a weak awareness of energy conservation, and the phenomenon of offices and classrooms being empty but brightly lit is common. The idea of "using electric lights casually and the school paying for them" is widely prevalent, and even some teachers and students have a strong resistance to energy conservation under the pretext of affecting scientific research and learning. In summary, the weak awareness of energy conservation is the fundamental reason why energy conservation management is difficult to implement effectively.

　　(2) The level of operation and management teams varies greatly.

　　The maintenance team of university power systems is usually composed of external workers with generally low knowledge levels and no relevant learning or training. They are only responsible for repairing and replacing damaged parts on a daily basis. However, the level of management team is generally not high, and the phenomenon of "outsiders and experts" is common. It is only necessary to ensure the normal operation of the power system. And there are multiple departments and multiple heads of management, lacking cooperation. Some management problems are even passed on to each other, let alone updating energy-saving equipment and designing and implementing deeper energy-saving solutions with a long-term vision.

　　Fine grained and graded management permissions.

　　The smart supervision platform for college electricity usage is divided into three levels of management permissions based on different users. The first level management is the school management department, which has all system permissions and authority allocation rights, including remote centralized monitoring, management and maintenance tracking of electricity safety, real-time access to warning and alarm information provided by the system, remote monitoring of electricity hazard parameters, hazard analysis and supervision. The secondary management includes dormitory management personnel, counselors, and college management departments, which implement fault warning, online query of real-time data, historical data, alarm logs, and statistical information of electrical circuits, locate electrical equipment faults, conduct hidden danger physical examinations, hidden danger investigation and rectification, and daily inspections. By using timely alarm functions and warning mechanisms, abnormal situations in the distribution system equipment and surrounding environment can be detected in a timely manner, and inspections and maintenance can be arranged to prevent accidents and electrical fires from the source. According to the scope of dormitory management, have the rights to set electrical circuit parameters, read data, download and print reports, and set time for all target dormitories within the scope. The third level management is for students, who have the right to view the electricity usage status and data of each circuit in this dormitory, but do not have control. You can decide whether to grant remote switch permissions based on management needs. Dormitory and office energy-saving management.

　　Through the intelligent electricity supervision platform, real-time monitoring of energy consumption sub items, time distribution, timing and quantity, power setting, and flexible allocation of energy consumption for lighting in various dormitories, teaching buildings, classrooms, and public areas in student dormitories is carried out. The comprehensive electricity consumption data is automatically summarized for intelligent analysis, timing control, remote control, etc., effectively reducing equipment power consumption during unmanned periods. Implement time management for lighting in student dormitories, classrooms, and public areas to achieve energy-saving and consumption reducing management. Provide data on voltage, current, and electricity consumption of lighting lines in various apartments, classrooms, and public areas. The fluctuation of electricity consumption data and electricity consumption are clear at a glance, promoting an environmentally friendly, low-carbon, energy-saving, and green lifestyle.
