Preface According to the "2017-2022 China Power Industry Special Survey and 13th Five-Year Plan Market Business Opportunities Analysis Report", from the current structure of electricity consumption in China, industrial and commercial users consume about 80% of electricity, of which motor power consumption accounts for about 75% of industrial electricity consumption and 60% of the total electricity consumption in the country, which is a large proportion of
user terminal power consumption.
Therefore, motor energy saving will become a key step to
reduce industrial energy consumption and achieve carbon peak and carbon neutrality as soon as possible.
2.
Two departments: carry out energy-saving transformation of existing motors to promote energy conservation and carbon reduction and green transformation in major industrial fields, resolutely curb the blind development of the national "two highs" projects, and ensure that the carbon peak goal
is achieved on schedule.
On October 29, 2021, the Ministry of Industry and Information Technology and the State Administration for Market Regulation jointly issued the notice
of 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 iron and steel, nonferrous metals, petrochemicals, chemicals, building materials, textiles and other industries to carry out energy-saving diagnosis of energy-using equipment, and evaluate the potential of the promotion and application of
advanced energy-saving technologies and equipment in combination with the energy efficiency level and operation and maintenance of equipment.
Guide enterprises to implement the renewal and upgrading of major energy-using equipment such as motors, give priority to the selection 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 motor systems such as fans, pumps and compressors that operate inefficiently
.
3.
How to carry out motor energy-saving transformation notice proposes to promote the intelligent and digital improvement
of the motor system.
Promote intelligent and automated motor manufacturing, accelerate the application of motor intelligent sensor series products, multi-sensor data unified technology, etc.
, and promote the integration of
motor system operation data collection, calculation, storage and communication.
Encourage the establishment of a digital collaborative manufacturing platform, promote the reasonable interaction of data between systems such as production planning, process technology, material distribution, equipment monitoring and maintenance, quality control, logistics tracking, etc.
, and centrally control process manufacturing and production control data
.
4.
Accuray motor monitoring platform helps enterprises motor energy-saving transformation Under the dual carbon policy, in the face of the carbon reduction and emission reduction needs of industrial enterprises, Accuray provides a full range of hardware products and system solutions in energy efficiency management, upgrading, equipment maintenance, energy saving and consumption reduction, etc.
, to help enterprises achieve energy-saving transformation
。 The Accuray motor monitoring platform real-time monitors various electrical parameter data of low-voltage motor circuits and feeder circuits in industrial sites, which can help users implement dynamic monitoring and data management of power parameters, energy consumption, power quality and operating status of motor equipment and important distribution circuits, and realize the visual management, intelligent monitoring and real-time supervision
of the company's important production equipment.
It can not only realize the real-time monitoring and automatic management of low-voltage electrical equipment and feeders, but also achieve the purpose
of reducing manpower waste and improving production efficiency.
The system consists of three major sectors: motor monitoring system, equipment operation and maintenance management system, and asset management system
.
The underlying access equipment includes: motor protector, anti-shaking device, line protector, multi-function instrument, frequency converter, soft start, temperature measurement equipment, vibration equipment, camera and some third-party equipment
that customers need to access.
System FeaturesThe motor monitoring system centrally monitors the access equipment, and real-time view the electrical parameters and equipment operating status
of the motor circuit and distribution circuit.
Through motor monitoring, the equipment with low operating efficiency and low load rate is found to provide data support
for energy-saving transformation.
Fault early warning real-time monitoring of motor alarm, alarm information generation operation report for repair, fault management information, easy to carry out fault diagnosis, such as electrical parameters at fault time, fault waveform, support all kinds of fault record report query
.
The energy consumption analysis system can carry out energy consumption analysis, including energy consumption overview, year-on-year analysis, chain analysis, energy consumption report, energy consumption forecast and other functions, and make a comprehensive analysis of motor energy consumption, providing a basis
for energy optimization in the later stage.
The health analysis system analyzes the health state of the motor and the health state of the electrical circuit, establishes the motor health model, and manages the threshold and weight
of each influencing factor 。 Equipment operation and maintenance management generates equipment maintenance reminders according to the maintenance schedule, temporary maintenance, emergency maintenance and other maintenance, and can be automatically linked with equipment health, life cycle management functions, generate corresponding repair letter system can be equipment management, customized management of access equipment, establish equipment ledger, formulate regular inspection plans, production efficiency optimization Through the comprehensive analysis of equipment running desk time, operating efficiency, load rate, energy consumption, health status and other data, reflect the real production efficiency, easy to adjust and optimize
。 5.
Conclusion The emission reduction generated by the improvement of stand-alone technology is still relatively limited, and more consideration should be given to the application scenarios
of motor products.
From the perspective of energy supply side, 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 of large-scale use of motor products, the smart microgrid can be introduced to monitor and rationally allocate
equipment energy in real time by changing the line planning and overall layout.
Through the motor monitoring system, the production efficiency optimization scheme is scientifically analyzed to make the motor run
as reasonably as possible.
