The trend of fluctuations in the overall economic development of the China in the past few years, the international economic situation is complex, in the next few years there will be a lot of uncertainty, coupled with the high margin market of the UPS industry, more and more enterprises will enter the UPS industry. United States, Western Europe and Chinese is the main production area of UPS.
In the next five years, the growth rate of global consumption of UPS will remain 6-8% or so. In the future, the areas where industrial UPS will grow faster will focus on power, manufacturing and so on. In manufacturing, due to the steady development of petrochemical enterprises and the large-scale application of large-scale equipment, the renewal rate of industrial grade UPS will not be too high in the future, and other areas such as light manufacturing and continuous production will develop rapidly. The installation rate of industrial UPS will be improved.
UPS product gross interest rate is very high, in China, the profit margin is above 35%. And in overseas, the gross interest rate is about 40-45%. In 2017, the scale of Chinese industrial UPS market is expected to reach more than 5 billion yuan.
With the development of UPS, the UPS industry in China has been more and more mature and advanced. Although Schneider and Emerson have great competitive advantages in China, domestic brands such as SOROTEC will also become leaders of industrial UPS in the future.

According to the results of two years’ investigation, it is known that the main inverter products in 2016 are overvoltage / undervoltage protection of AC output side, harmonic and waveform distortion. For two years, the overvoltage / undervoltage protection of the AC output side has become the most problematic project. Why is there always problems?
It is understood that the overvoltage / undervoltage protection AC output side, that is the solar power station supply power to the power grid through the solar inverter, when the inverter AC output terminal voltage exceeds (or below) the allowable voltage range of the power grid, the inverter will automatically disconnect the AC contactor, stop power supply, and also issued a warning signal. The function of the inverter is very obvious, that is, to ensure the safe power supply of the solar power station on the premise of guaranteeing the stability. For the power grid, a large number of access over the allowable voltage range is likely to cause damage to the stability of the grid. Because of the unstable characteristics of solar power station, the performance of inverter’s output voltage and undervoltage protection determines the grid friendliness of solar power generation, and its importance is self-evident.
The over voltage protection value of the solar panel power inverter is 195.5V-253V, and it is not a very difficult technical standard to realize. But why has it become a heavy disaster for solar inverter products for several years? This may be related to the uneven level of domestic power grid construction. For example, there are some problems in some parts of China, such as insufficient distribution transformer capacity, too large load / too small load, resulting in high voltage range of 270V and low 180V. In order to adapt to the complex conditions of these areas, some businesses may broaden the over voltage protection range of the inverter to enhance the adaptability of the inverter.
In addition, in the era of power generation, a wider range of over voltage and undervoltage protection will enable the power station to incorporate more power into the power grid, which will increase the power plant benefits. But if all solar power stations ignore the stability of the grid and frantically output the power beyond the safe range, this will inevitably damage the stability of the power grid and bring potential security risks. Once the stability of the power grid is affected by the access of solar power, the power limit will be inevitable.
To solve these problems, on the one hand, Chinese power grid construction still need to be improved, and according to the characteristics of new energy and electricity such as solar and wind power, we will improve the power grid technology, overcome the difficulties of new energy and power instability, and maximize access to new energy and electric power. On the other hand, it is necessary to improve the stable output of the solar power plant to ensure that the output voltage of the solar power is within the safe range.

Under the premise of ensuring information security, air traffic management, airline operation and management, airport operation management and other businesses gradually develop into “cloud data integration and innovative application”.
Power supply system from decentralization to centralization
The trouble of traditional decentralized power supply As the core system of the infrastructure, the primary concern of the construction department of the Chongqing Jiangbei International Airport’s new terminal is the power supply system of the equipment. Once a power supply failure occurs, it will cause huge losses to the airport. The traditional power supply system uses distributed power supply, that is, one device corresponds to a small UPS. For example, the security channel, check-in, boarding, baggage and other original using decentralized 20-80kVA UPS power supply. Not only is it not convenient to disperse and maintain, but once it fails, it will be difficult for manufacturers to repair and maintain time, which will bring great trouble to airport electromechanical maintenance department. The distributed small UPS is inefficient, and most of the UPS efficiency of the present network is less than 90%, which can not meet the needs of energy saving and emission reduction at present.
Trend of centralized power supply system The new terminal of the airport construction department, through the investigation of the existing scheme and after full discussion, decided to adopt the centralized power supply, to replace the original decentralized power supply system, the security channel, the original check-in, check-in, baggage and other scattered small capacity UPS power supply area with large capacity UPS centralized power supply. Considering the voltage loss and other problems, the power supply distance of the region can not exceed a certain range, and the UPS centralized power supply capacity is generally above 200kVA. Through the centralized power supply, the power supply efficiency of the system will be greatly improved and the index of energy saving and emission reduction can be realized. At the same time, centralized power supply also solves the problem of decentralized maintenance. The power supply is centralized, and the reliability of the system is higher. The 2N power supply system of power supply structure, redundant double bus system to improve the reliability of the power supply system, the fault of single equipment will not risk the system downtime.

There are a wide variety of MPPT solar controllers, and the selection of suitable models for solar street lamps needs to be taken into consideration in several aspects.
1.The power and voltage of a solar component.
If the solar panels below 120W/18V, 10A controller is OK, if 120V/18V~240W/18V solar panels, then use 20A street lamp controller.
2.Whether the LED light source has a built-in drive power. If the light source itself does not drive the power supply, then the constant current control unit with constant current should be selected. If the light source itself is powered by the power, then the ordinary type of solar street lamp controller should be chosen.
3.The light source with drive to see the arrangement of the lamp. If the 3 series is in parallel, the step-down constant current control unit is used, if it is more than 5 series, the lifting type constant current control unit is used.
4.According to the use of the environment. If it is outdoor, and there is no special sealing box, it is necessary to use the full waterproof IP68 grade solar energy street lamp controller. If there is a special sealing box, also can choose the plastic shell IP32 grade solar street lamp controller.
