　　Main practices of "systematized management of intelligent substation operation and maintenance"

　　The basic idea of systematic management for the operation and maintenance of intelligent substations is to follow the principles of systematization, control according to the PDCA process, adopt the 5W1H working method, and implement the operation and maintenance work of intelligent substations in stages and levels according to standards and specifications. The main approach is to carry out systematic and standardized management from six aspects: data management, equipment acceptance, security management, operation and maintenance management, equipment management, and training work. Drawing on the mature and complete management methods of existing conventional stations, we will supplement and improve the series of intelligent station operation and maintenance management methods that are different from conventional stations.

　　1、 Introduction to Substation Operation and Maintenance Cloud Platform

　　According to the statistics of State Grid Corporation of China, there are over 2 million industrial and commercial users with a power supply voltage level of 10kV and above. The property rights of such "user side substations" belong to the power users (industrial and commercial enterprises, residential communities, schools, etc.). Although there are many of them, the daily operation and maintenance work is relatively traditional, and there are generally the following pain points:

　　High labor costs: manual inspections, paper records, telephone communication, lack of intelligent means

　　Low work efficiency: low video inspection rate, inability to locate inspection tasks, non-standard inspection process, lack of closed-loop tracking of inspection defects;

　　Safety hazards: Some electricity consuming units face difficulties such as lack of maintenance electricians, inability to promptly identify electrical hazards, and difficulty in inspecting hidden engineering hazards; Long repair time: There are many types of substation equipment, which are also scattered in distribution, making it difficult to identify and locate fault information in real time. Users need to notify and confirm on-site;

　　Lack of analysis in running big data: Some users do not have a data aggregation and analysis platform, and even have not installed power instruments, resulting in operation and maintenance personnel not understanding the on-site power parameter information and unable to determine whether the power system is operating normally.

　　Function:

　　With the gradual promotion and implementation of the national grid reform policy, the ordinary offline operation and maintenance mode has been unable to meet the market demand, and it is urgent to support the intelligent online operation and maintenance management and service platform. The operation and maintenance cloud platform of Ankeri substation (AcrelCloud-1000) provides supporting online operation and maintenance services for power operation and maintenance companies based on market demand feedback, using the Internet and big data technology. This platform serves as a link between operation and maintenance units and power consumption enterprises, monitoring the operation status and power data of user distribution systems, providing customers with better operation and maintenance services. The platform provides system overview, power data monitoring, power quality analysis, power consumption statistical analysis, daily/monthly/annual power statistics reports, abnormal warning, accident alarm and event recording, operating environment monitoring, operation and maintenance inspection dispatch, and supports multi platform and multi terminal data access.

　　3、 Main functions of the substation operation and maintenance cloud platform

　　Comprehensive Dashboard

　　Through the comprehensive dashboard, the overall operation of the platform can be understood, and multiple templates are pre-set for users to choose from. It is the window and centralized control center for the platform to display to the outside world

　　Power monitoring

　　Real time monitoring of substation electricity usage through vector distribution diagrams, with screen response to remote signal displacement and remote sensing limit alarm. Clicking on a distribution circuit allows for the query of various detailed electricity parameters, including real-time values, small values, values, and average values;

　　environmental monitoring

　　Real time monitoring of the operating environment of the substation, including environmental temperature and humidity, water immersion, door magnets, smoke detectors, cable temperature, etc., and can achieve video monitoring and video playback;

　　Fault Alarm

　　Configurable remote signal displacement alarm (water immersion, smoke, door magnetic, switch tripping, etc.), telemetry limit exceeding alarm (overvoltage, undervoltage, overcurrent, cable temperature too high, winding temperature too high, etc.), operation alarm (instrument offline, gateway offline, etc.), and the received alarm can be pushed through SMS and web pages. The upper and lower limits of the alarm can be flexibly configured according to the on-site situation;

　　energy efficiency analysis

　　Collect hourly, daily, monthly, and annual electricity consumption data based on distribution circuits, regions, departments, and sub items (lighting, air conditioning, power, etc.), and conduct month on month analysis; Calculate the electricity consumption and amount of each distribution circuit according to peak, off peak, flat, and valley; Monthly statistics on the demand and occurrence value of each circuit, providing a basis for demand declaration;

　　Equipment File

　　The system can configure equipment information such as transformers, incoming cabinets, outgoing cabinets, metering cabinets, high-voltage cables, etc. in each substation, record the manufacturer, model, commissioning date, etc. of the equipment, and can use reports to count the equipment that needs maintenance or replacement in the near future;

　　Inspect and eliminate defects

　　Develop an inspection plan through the system and distribute it to the inspectors' mobile phones. The inspectors will perform inspection tasks at the substation site according to the inspection requirements. If defects are found during the inspection process, they can record the defects and generate a defect elimination task in the system;

　　User Report

　　The system automatically summarizes the operational data of the substation for one month, conducts statistical analysis on transformer load, distribution circuit electricity consumption, power factor, alarm events, etc., and lists various defects and their handling situations discovered during the inspection period;

　　On site hardware configuration

　　5、 Business model of substation operation and maintenance cloud platform

　　1) Data hosting method

　　Ankrui guides users to complete the installation and debugging of intelligent instruments, current transformers, residual current transformers, temperature sensors, door magnets, network cameras, wireless modules, etc. Users upload data to the Ankrui substation operation and maintenance cloud platform, entrust Ankrui to manage, and charge software basic fees and hosting fees according to regulations/agreements.

　　2) User built platform

　　Support platform self construction

　　Allocate resources according to need

　　One of the characteristics of cloud computing technology is that resources can be allocated dynamically on demand. This is mainly reflected in two aspects: One is set when the virtual machine to establish all kinds of virtual resource value is not in the virtual machine just start the physical machine is assigned the corresponding amount of hardware resources to the virtual machine, but with the resources needed to actually run the virtual machine, the physical resource dynamically allocated to the virtual machine in order to assure its operation, so that the physical machine to create more virtual machine, The value of the specified VM resource value can be greater than the actual dedicated machine resource value to improve the dedicated machine resource usage. Second, the virtual resource values set for VMS can be flexibly adjusted based on service requirements. In traditional systems, hardware resources need to be expanded as the service volume increases. The expansion process is long, requiring process approval and taking a long time. In addition, the expansion may be limited by hardware devices and cannot meet the expansion requirements. However, in the cloud platform, it is very easy to expand the capacity of virtual machines. You only need to adjust the size of virtual resource values, and you can quickly create new virtual machines on the cloud platform according to users' new business requirements, which can save a lot of time compared with the traditional system.
