A brief discussion on energy-saving transformation scheme of motor monitoring system

1. Introduction

According to the "2017-2022 China Electric Power Industry Special Survey and 13th Five-Year Market Opportunity Analysis Report", from the perspective of my country's current electricity consumption structure, industrial and commercial users account for about 80% of electricity consumption, of which motor power consumption accounts for about 75% of industrial power consumption and 60% of the country's total power consumption, which is a relatively large proportion of user terminal power consumption. Therefore, motor energy saving will become a key step in reducing industrial energy consumption and achieving carbon peak and carbon neutrality as soon as possible.

2. Two departments: carry out energy-saving transformation of existing motors

In order to promote energy conservation, carbon reduction and green transformation in major industrial fields, resolutely curb the blind development of "two high" projects across the country, and ensure that the carbon peak target is achieved as scheduled. On October 29, 2021, the Ministry of Industry and Information Technology and the State Administration for Market Regulation jointly issued the "Motor Energy Efficiency Improvement Plan (2021-2023)". The notice proposes to carry out energy-saving transformation of existing motors. Encourage major industrial industries such as steel, nonferrous metals, petrochemicals, chemicals, building materials, and textiles to carry out energy-saving diagnosis of energy-consuming equipment, and evaluate the promotion and application potential of advanced energy-saving technologies and equipment based on the energy efficiency level and operation and maintenance of the equipment. Guide enterprises to implement the renewal and upgrading of major energy-consuming equipment such as motors, give priority to the use of reasonable energy-saving motors, and accelerate the elimination of backward and inefficient motors that do not meet the requirements of the current national energy efficiency standards. Encourage enterprises to carry out matching energy-saving transformation and operation control optimization for inefficient motor systems such as fans, pumps, and compressors.

3. How to carry out energy-saving transformation of motors

The notice proposes to promote the intelligentization and digitalization of motor systems. It promotes the intelligentization and automation of motor manufacturing, accelerates the application of motor intelligent sensor series products, multi-sensor data unification technology, etc., and promotes the integration of motor system operation data collection, calculation, storage, and communication. It encourages the establishment of a digital collaborative manufacturing platform, promotes the reasonable interaction of data between systems such as production planning, process technology, material distribution, equipment monitoring and maintenance, quality control, and logistics tracking, and centrally controls process manufacturing and production control data.

4. Ankerui Motor Monitoring Platform helps enterprises to transform their motors into energy-saving ones

Under the dual carbon policy, facing the carbon reduction and emission reduction needs of industrial enterprises, Ankerui provides comprehensive hardware products and system solutions in energy efficiency management, upgrading and transformation, equipment maintenance, energy conservation and consumption reduction, etc., to help enterprises achieve energy-saving transformation.

The Ankerui Motor Monitoring Platform monitors various electrical parameter data of low-voltage motor circuits and feeder circuits at industrial sites in real time, and can help users dynamically monitor and digitally manage the power parameters, energy consumption, power quality and operating status of motor equipment and important distribution circuits, and realize visual management, intelligent monitoring and real-time supervision of the company's important production equipment. It can not only realize real-time monitoring and automated management of low-voltage electrical equipment and feeders, but also reduce manpower waste and improve production efficiency.

The system consists of three major parts: motor monitoring system, equipment operation and maintenance management system, and asset management system. The underlying access equipment includes: motor protector, anti-sway device, line protector, multi-function instrument, inverter, soft starter, temperature measurement equipment, vibration equipment, camera, and some third-party equipment that customers need to access.

System features

● Motor monitoring

The system conducts centralized monitoring of connected devices, and checks the electrical parameters of the motor circuit and the power distribution circuit, as well as the operating status of the equipment in real time. Through motor monitoring, it can identify equipment with low operating efficiency and low load rate, and provide data support for energy-saving transformation.

●Fault warning

Monitor the motor alarm status in real time, generate operation reports for repair when alarm information appears, and manage fault information to facilitate fault diagnosis, such as electrical parameters and fault waveforms at the time of fault, and support various fault record report inquiries.

●Energy consumption analysis

The system can perform energy consumption analysis, including energy consumption overview, year-on-year analysis, month-on-month analysis, energy consumption report, energy consumption forecast and other functions, and make a comprehensive analysis of motor energy consumption to provide a basis for subsequent energy optimization.

Health analysis

The system analyzes the health status of the motor and the electrical circuit, establishes a motor health model, and manages the thresholds and weights of each influencing factor.

●Equipment operation and maintenance management

Generate equipment maintenance reminders according to the maintenance schedule, temporary maintenance, emergency maintenance and other maintenance, and can automatically link with the equipment health and life cycle management functions to generate corresponding repair letters. The system can manage and customize the access equipment, establish equipment records, and formulate regular inspection plans.

●Production efficiency optimization

Through comprehensive analysis of equipment operating hours, operating efficiency, load factor, energy consumption, health status and other data, the real production efficiency can be reflected, facilitating adjustment and optimization.

5. Conclusion

The emission reductions from the improvement of single-machine technology are still relatively limited, and more consideration should be given to the application scenarios of motor products. From the perspective of energy supply, the use of new energy and distributed energy can be increased in the application scenarios of motors; from the perspective of energy demand, in the application scenarios where motor products are used on a large scale, by changing the line planning and overall layout, smart microgrids can be introduced to monitor the energy consumption of equipment in real time and reasonably allocate it. Through the motor monitoring system, scientific analysis of production efficiency optimization plans can be carried out to make the motor operate as reasonably as possible.
