Construction of operation and maintenance cloud platform for industrial and mining substations

Description :

　　Analyze user needs and provide differentiated services

　　With the increasingly fierce competition in the electricity market, it is necessary to gradually transform universal services into differentiated services, that is, to continuously refine customer services and improve the efficiency of customer service. It is mainly divided into two categories: large customers and resident customers. For large customers, their electricity demand mainly includes continuously reducing the cost and consumption of energy, reducing carbon dioxide emissions, optimizing the combination of electricity prices and related electrical equipment plans, developing reasonable energy mix plans, and providing energy-saving services.

　　Construction of operation and maintenance cloud platform for industrial and mining substations

　　1、 Introduction to Substation Operation and Maintenance Cloud Platform

　　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;

　　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

　　Improve the operational quality of substation staff and whether they are proficient in it

　　The management of substation operation and maintenance mainly revolves around various substation equipment, and this control work directly affects the work efficiency that power enterprises can ultimately obtain. In order to ensure the continuity and reliability of power supply work, the current level of substation operation and maintenance management needs to be further improved. Operation and maintenance personnel should not only carry out necessary regular inspections, but also control detailed technical issues during daily patrols, maintain power equipment, and reduce erroneous operations in the operation and maintenance control process. After starting the automatic operation and maintenance management system, there should be no arbitrary handling of operation and maintenance control work. When dealing with grounding faults, work records should be kept during shift handover.

　　With the continuous deepening of China's power system reform, the electricity market is gradually opening up electricity sales to society. This requires electricity sales companies to study strategies related to bidding for electricity purchase. The opening up of the electricity sales side will transform the traditional electricity sales model, allowing users to freely choose the quantity of electricity purchased, thereby making China's electricity supply safer and more efficient.
