The inverter has huge market potential in the next few years

Since the "Twelfth Five-Year Plan" was promulgated, energy-saving and emission-reduction has been the key to the development of various industries. At this time, various energy-saving and environmentally-friendly products have been applied more widely and the prospects have become clearer. Benefited from the strategy of energy conservation, emission reduction and green environmental protection, inverters are important equipment in the field of variable frequency speed control, and their industries have great market potential in the coming years.

In large-scale distributed renewable energy power generation, frequency converters play an important role in both power electronics and information and communication technologies.

With frequency converters, homeowners and public operators can realize all the benefits of distributed and centralized renewable energy systems.

The inverter industry has begun to greet the changing era of technological innovation, which is also a time of chaos.

According to a survey by PikeResearch, the global market for inverters for renewable energy sources in 2011 was 7.2 billion U.S. dollars. It is predicted that the scale will be doubled in the next five years and will surpass $19 billion by 2017.

The initial use of the inverter driven by industrial energy-saving is speed control. With the development of technology and society's increasing energy efficiency requirements, it is gradually being used in the field of energy conservation.

According to calculations, the energy-saving rate of motor systems using inverters is generally around 30%, and that of some high-level applications is up to 40% to 60%. Energy-saving effects are significant. Today, inverters are the development direction of motor energy saving.

According to reports, the frequency conversion speed control technology used in the coal industry earlier is the mine hoist. At present, developed countries have used inverters commonly used in belt conveyor speed control or belt conveyor start control, fan speed control and water pump. Speed ​​adjustment. The use of frequency converters in the above devices, in addition to improving transmission performance, more importantly, can save energy.

The energy saving, emission reduction and consumption reduction in the power industry are even more severe. Since frequency converters can efficiently save energy and improve the technological level in many industries, to a certain extent, vigorously promoting the application of frequency converters in various industries can reduce the pressure on power generation indicators in the power industry, save energy, and reduce emissions. Quantity, reduce energy consumption.

“On the other hand, the electric power industry is also one of the important application fields of frequency converter products. From the control process related to frequency converters in China's thermal power plants, the drive devices for wind, coal, water, slag and exhaust gas systems are suitable for medium and low pressure. The application of frequency converter," said a technical person in charge of an inverter manufacturer in Beijing.

Frequency conversion energy-saving will become the main battlefield of the future, automation control can not be separated from the inverter, low-voltage electrical equipment is more space for the development of the inverter; the face of this trillion of "feast", the inverter industry can give birth to geometry?

The starting current of the motor using the inverter starts from zero and gradually increases. The maximum value does not exceed the rated current, which reduces the impact on the power grid and the requirements on the power supply capacity, thereby achieving the effect of energy saving and extending the service life of the equipment. Equipment maintenance costs.

Especially in the field of fine processing, through the high-speed control of the motor speed by the inverter, the manufacturing process level can be greatly improved. It can be said that the inverter is currently the most ideal and most promising motor energy-saving equipment, and almost every industry in the national economy is inseparable from the inverter.

Although the frequency converter has many advantages, due to the price issue, its large-scale promotion and use is currently restricted, and it is in an embarrassing situation of “being good or bad”.

There are more than 300 frequency converter production plants in China, but their strength and scale are uneven. Individual companies still use workshop-style production models, and the main brands are maintained at 20-30.

The domestic inverter market is developed with the entry of foreign brands. The foreign brands are predominantly in the market, and currently occupy about 70% of the domestic inverter market.

The history of the establishment of most local companies is not long. Many products enter the market for a short period of time. It is still difficult to compete with internationally renowned brands in terms of product maturity and brand awareness. Local companies mainly produce V/F control products. For products with superior performance and high technological content, such as vector inverters, most companies in China have not yet developed mature products.

In addition, the personnel and funds of domestic-funded brands have been continuously separated and many companies have been established, mainly in coastal areas such as Guangdong, Zhejiang, Shandong, and Shanghai. With the intensification of market competition, many brands will be phased out. The future inverter market will be a market with higher brand concentration and more orderly competition.

For example, the operations of some inverter manufacturers are outsourced, such as outsourcing some inverter components. Due to improper management, there are potential quality risks.

With the rise of local brands, the market share of local inverter companies is gradually expanding, especially in recent years, the trend of accelerating the substitution of foreign brands.

At present, due to constraints in technology and capital strength, the development of local companies has been “situated.” According to industry experts, the current growth rate of the installed capacity (power) of the upconverter in the Chinese market is actually around 20%. It is expected that the inverter market will be saturated and gradually mature after at least 10 years.

The market size of medium and low-voltage electrical equipment converters has increased at a level of 10% to 15%, but the growth rate in 2011 exceeded that of high-voltage converters for the first time, achieving an accelerated development of 30%. The market size is expected to be close to 20 billion yuan.

However, experts have warned that the low- and medium-voltage electrical equipment inverter industry is a strong cycle industry and is closely related to the national economic cycle. At the same time, although the driving factors of automation and upgrading of high-end equipment do not change, but under the strict national tightening policy last year, some SMEs due to raw material prices, labor costs and loan difficulties, the capital of new equipment procurement and technological transformation Sex investment is facing financial difficulties and the demand for frequency converters has slowed down. The use of acceptance bills by small and medium-sized users has also reduced the enthusiasm of channel developers for market development.

Energy-saving converter market prospects are very attractive According to statistics, China's total potential converter market space is about 120 billion to 180 billion yuan, of which atmospheric frequency inverters account for about 60% of the market share, the number of medium and high voltage inverter demand Relatively few, but because a single inverter power, high price, but also accounted for about 40% of the market. At present, there are at least 180 million kilowatts of electric motors with variable load and potential for energy conservation in China, which provides a very large market for the application of frequency converters.

The data shows that in recent years, China's inverter market has maintained a growth rate of 12% to 15%, and it is expected that at least in the next five years, the inverter market demand will still maintain a growth rate of more than 10%. After 10 years, the inverter market can gradually become saturated.

Of course, with the advancement and diversification of user requirements, the functions of the inverter products are constantly improving and increasing. The degree of integration and systemization are also getting higher and higher, and special energy-saving frequency converter products have appeared in some fields. The energy-saving principle of the frequency converter is as follows: The frequency converter enables the motor and its drag load to adjust the speed output according to the production process requirements without any modification, which reduces the power consumption of the motor and has a unique and unique advantage in the field of energy conservation and emission reduction. The goal of efficient system operation has been achieved. China's common and market-occupying inverter brands are:

Imported brands ABB, Siemens, Yaskawa, Fujitsu, Delta, Schneider, Emerson, Mitsubishi, Danfoss, Rockwell and others.

Domestic brands: I hope Senlan, Cornwall, Oerlikon, Invensys, Sine, Huichuan, Bosch Lux, and Hailipu.

As a whole, the competition in China's inverter industry is increasingly fierce. As the market is very attractive, not only the market has formed a certain scale, but also the potential capacity is very considerable. It constantly attracts new participants in the industry, and the development of frequency converter technology makes the frequency converters in power, cement, elevators, mines, metallurgy, and traffic. Unprecedented promotion and application in other modern fields, it is believed that the application of frequency converters will become more and more extensive and the market prospects are promising. Inverter companies should use the "12th Five-Year Plan" to save energy and reduce emissions to better establish the concept of energy conservation. The energy-saving performance of the product is further upgraded, which is very favorable for the future development of the inverter company.
