Technology is always in the development and has now entered the digital age, the new technology to replace the old technology is the law of history, the level of competition increased significantly, which is also true in UPS power supply industry.

 

Advantages of high frequency UPS

1.Low power consumption
In the same index, such as the input power factor is above 0.95, the UPS must be applied in low frequency harmonic filter or changed to 12 pulse rectifier, that is to increase a device in the front, coupled with the output transformer, two more links than high frequency UPS. Due to the influence above, the efficiency of the low frequency UPS is 5% lower than that of the high frequency UPS. In the same capacity of 100kW, low frequency UPS consume more 50 thousand kwh of electricity each year than the high-frequency UPS! This has far-reaching significance in energy saving and emission reduction today.

2.High input power factor
Low frequency UPS is generally below the input circuit of the 200kVA, using a SCR 6 pulse rectifier, the input power factor is not over 0.8, the harmonic current is up to 30%. If use the front generator, the generator capacity of at least 3 times as much as UPS power; if it is a single-phase low power UPS, the generator capacity of at least 5 times of the UPS. Any capacity of high-frequency UPS input power factor can be 0.99 or more, the harmonic current is less than 5%, the capacity of the generator and UPS power in theory the same, greatly reducing the investment and floor area, etc., which is of great economic and social significance to make full use of the electricity market. The machine and circulation attenuation can be reduced to almost zero. The parallel of the low frequency UPS is the direct parallel connection of the transformer, and the direct parallel connection of the transformer is most likely to produce the circulation, and the path of this circulation is unimpeded.

3.Small size, light weight
Low frequency UPS because of the output transformer and the low frequency components, such as the capacitance adapt to 50Hz, and the bulk weight is very large. For example, a 200kVA low frequency UPS weight 1380kg, while the 250kVA high frequency UPS weight only 830kg.

4.Full digital technology
Low frequency UPS initially using simulation techniques, now generally developed as a combination of digital and analog technology. The reliability of simulation technology is lower than that of digital technology. The high frequency UPS is a full digital technology, obviously that the reliability is very high.

5.Small external interference
There are two kinds of interference, one is the mechanical noise can be heard, one is the electrical noise cannot be heard, low-frequency UPS have both kind of these two noise, forming the harm to people and the device. The electrical noise affects the stability of the machine, and the mechanical noise affects people’s physical and mental health and reduces the working efficiency. The high frequency UPS due to work in more than 20kHz, and it is the frequency which human ear can not hear, so that the working environment is quiet. And because of the high frequency UPS input power factor up to 0.99, almost linear, so the external interference is almost zero.

6.Strong ability to adapt to the grid
Low frequency UPS is very difficult to adapt to the change of input voltage ±15%; The high frequency UPS and even adapt to the input voltage of more than ±30% of the change, which greatly extends the battery life.

With the deterioration of the climate, renewable energy development has become the mainstream of the world. With policy guidance, government subsidy and capital investment, solar energy and other new energy companies are developing rapidly. But compared with conventional energy, under the competition of cost and technology, the survival of the fittest solar inverter companies also entered the accelerated phase. The solar energy inverter which is the key equipment of solar power plant as an example, related enterprises in 2012 Chinese market up to 300, while it is reduced to about 100 in 2015, and only more than and 10 active solar inverter companies in 2016.

2015, Chinese solar energy installed capacity exceeded Germany became the world’s first. At the same time, the transformation is happening quietly: subsidies backslide forced the technical innovation of enterprises to achieve cost breakthrough, then implement of solar “leader” plan to promote technological upgrading of enterprises and enhance the quality of products, to carve up the market by technology.

In this context, the solar energy industry accelerated the pace of technological innovation. The conversion efficiency of 2016 Chinese commercial monocrystalline silicon, polycrystalline silicon cells reached 20.5% and 18.5% respectively, centralize, distributed and string solar inverter technology route diversity, overlay maintenance and more intelligent, to promote solar electricity price become lower. While talking about the technological innovation of enterprises is not empty talk, but should be guided by the actual market. Looking at the current Chinese solar market, one of the biggest changes is the eastward shift, the earliest start in 2015, in fact, has become a foregone conclusion in 2016.

Different from the flat terrain of western, eastern with more mountain and forest, the utilization of solar energy is mainly with the distributed solar inverter. In this view, this market trend also contributed to the performance of some series solar energy inverter companies gained in 2016. Due to the complex terrain, the component is different and the shadow blocked the sunshine, the multi-channel MPPT series inverter has obvious advantages.

The 2017 solar electricity price down, but distributed solar subsidies are not adjusted, the dividend policy to continue promoting distributed solar power generation. In addition, the scale continues to expand the solar leader demonstration base has become the mainstream, combined with solar poverty alleviation, or the next solar three core markets, technological innovation of solar inverter companies will continue to extend.

At present, high frequency tower type UPS and modular UPS can achieve 96% highest efficiency value, but this can only be achieved over 50% load rate. As mentioned above, because of system redundancy and advance planning, the UPS load rate is about 20~40% under common conditions. High frequency tower UPS under this condition can only achieve the efficiency of 94~95%, while the mainstream modular UPS generally have a “dormant module” characteristics based on a certain system redundancy, can sleep a certain number of modules (can be manually or automatically), keep the work rate of modular UPS system in the relatively high area, which remain in 96% of the highest point of efficiency.

And some modular UPS manufacturers considering the module aging time may be different, develop the “rotation dormancy function”, namely every set period, rotate the dormancy module, average aging time of each module, to improve the overall UPS system life.

The Pakistan Premier Energy Consultant Zahid Mozafar said at a round table held on Tuesday which theme is that the enterprises to participate in the development of efficient hybrid energy structure, in order to develop the national alternative energy resources to alleviate the power crisis in the country, plans to switch 20000 households electricity system to the hybrid solar inverter system. He pointed out that Pakistan’s domestic natural gas production is 4 billion cubic feet per day, the gap between the domestic demand of about 8 billion cubic feet. The establishment of Pakistan’s first liquefied natural gas station has to help to increased the power supply to Pakistan agricultural fertilizer and textile industry, the country will also build more liquefied natural gas station in the next two years, to overcome the problem of energy shortage. He called on enterprises to develop a large number of domestic hydropower, coal, wind power and other alternative energy resources to reduce dependence on fossil fuels. He suggested that companies set up solar plants to meet the country’s energy needs, but also to sell surplus electricity to the national grid, to obtain substantial profits.
