The traditional manufacturing industry uses a large amount of manpower for processing, and today's cost is increasing. The high pressure of international competition, automation technology is increasingly accepted by the manufacturing industry. The smart factory made up of robots will become the future direction of the factory.
However, the large number of automated devices means that the plant needs to consume more power. In addition to improving production efficiency through automation technology, factories must consider how to minimize energy consumption. At present, there are many ways to save energy in the factory, but it is mainly reflected in the management savings of electric energy, such as the use of high-efficiency motors, inverters and smart energy management systems.
The ultimate goal of energy efficiency management system energy efficiency management system implementation is to achieve energy saving and improvement of existing systems through intelligent system integration. The energy efficiency management system measures the energy consumption of the main energy-using facilities and equipment, and then uses the intelligent system to save and improve.
With the increasingly fierce competition in the market and the gradual increase in energy costs, the awareness and requirements of automation equipment and energy efficiency management are gradually increasing, and the close integration of informationization and automation is proposed. High requirements. How to use the industry's innovative technology and successful application experience to help enterprises improve their information integration, operation and maintenance management capabilities and energy efficiency optimization is the mission of the majority of automation companies.
ABB's cpmPlus energy management software helps customers in all industries establish industry monitoring, management and optimization of energy efficiency and cost savings. Solve energy management business issues by developing accurate energy demand plans and applying them to energy supply planning and optimization. The software's ability to accurately prioritize energy requirements provides an important financial advantage, especially in the open electricity market, which ultimately reduces energy costs.
High-efficiency motor reduces power consumption. Most of the production machinery used in the processing industry is driven by electric motors. The motor is the main power consumption object in automation equipment. At present, China's industrial energy consumption accounts for about 70% of the total energy consumption. Energy consumption accounts for 60~70 of industrial energy consumption.
At present, the industry has introduced a new generation of high-efficiency motors. High-efficiency motors take measures from design, materials and processes, such as reasonable positioning, rotor slot number, fan parameters and sinusoidal windings to reduce losses and improve efficiency. Compared with ordinary motors, high-efficiency motors have an average loss of about 20, while ultra-efficient motors have lost more than 30 losses on average.
Inverter energy saving In addition to the development of high-efficiency motors, the use of variable frequency speed control technology is another effective energy-saving measure. High-efficiency motor and variable-frequency motor test put forward high requirements on the function and performance index of test equipment. In order to accurately obtain the efficiency of the motor, a broadband power analyzer with microprocessor and a high-precision frequency conversion power transmitter should be used. /sensor.
The energy saving of the inverter is mainly reflected in the application of fans and pumps. In order to ensure the reliability of production, all kinds of production machinery have a certain margin when designing with power drive. When the motor can't run under full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in wasted power. When using variable frequency speed regulation, if the flow demand is reduced, the speed can be met by reducing the speed of the pump or fan. The role of the motor in the frequency converter is to speed up and reduce the starting current.
Since the development of inverters in China, frequency conversion technology has achieved remarkable energy-saving effects in many production processes. The stability of product quality is gradually improved, and with the advantages of service and price, the competitiveness of domestic manufacturers will become stronger. At present, some domestic brands such as Delta, Senlan inverter, Huichuan inverter, and Yingweiteng inverter have been launched, and have already occupied a certain market share in China.
Intelligent lighting systems Effective energy-saving lighting is indispensable in traditional industries, and the dependence on light in automated plants is much lower, and even lighting systems can be used in the workshop. Intelligent lighting control systems are used to help the plant save power. Intelligent lighting control system must comply with the current concept of energy saving and environmental protection. Because lighting has always been a major city power consumer, it is a problem that must be solved if energy saving and environmental protection are realized under the premise of ensuring lighting demand.
The energy illumination system utilizes advanced electromagnetic voltage regulation and electronic induction technology to monitor and track the power supply in real time, automatically and smoothly adjust the voltage and current amplitude of the circuit, improve the additional power consumption caused by the unbalanced load in the lighting circuit, and improve the power. Factors that reduce the operating temperature of the luminaires and lines to achieve a lighting control system that optimizes the power supply.
In the next few years, the market size of China's LED light source will exceed 100 billion US dollars.
