One day of last September, a row of large container trucks, load♥ed with more than 100 wind turbine inverters, filed out of Zhejiang HIT•E Renewable Energy’s gate, heading for the destination-Xinj®iang.

 

This order was by no means big, but it’s the most special one among¶ a considerable number of orders last year.

 

The reason lied in the fact that a new component, the→ palm-sized smart card, was added in the control system of each wind turbine inverter.

 

"It means a 'personal health consultant' to each machine, and an extremely responsible₽ 'intelligent staff' to the company." Seeing this b©atch of special products off, Ji Jianqiang, the deputy general manager of R&D Depart ment of Zhejiang HITE Renewable Energy, seems expectant anεd excited.

 

What on earth is special about this smart card with dual ‍function?

 

They made it in advance while their peers are still thinking about it

 

The last decade saw a hot trend of domestication of wind power installation and scale§ expansion of wind power generation in China. HITE Renewable Energy started 7 yearσs ago, and is one of the older wind power enterprises in China.

 

HITE Renewable Energy products stretched over most regions of th♥e country during the past 7 years, of which Chen Chaofeng, the de♦puty general manager of HITE Renewable Energy Co., Ltd., is directly aware.

 

On a map of China, more than a hundred colorful pushpins were thumbtacked on provinces‌ and regions from Northeastern China to Hainan Island and> from Xinjiang to Yunnan. "Our products are mainly soβld in Inner Mongolia, Xinjiang, Ningxia, Shaanxi, Yunna"n and etc." Chen Zhaofeng was rather proud to introduce tha→t HITE Renewable Energy’s market share was among the top three in China."

 

The first simulation test platform, the first enterprise granted low voltage ride ↑through test certificate by China Electric Power Research Insti♣tute, the first domestic enterprise awarded 1.5 MW low voltage ride through (LVRT¶) converter test certificate by German MOE authentication company…... attitude and ef÷forts of HITE Renewable Energy to excellence are visible from R&D, testing to manuf↓acturing.

 

Ideas will blossom finally once conceived. HITE Re newable Energy embarked on the research work since early 2014, and the first b§atch of products realizing this idea were finally delλivered by HITE Renewable Energy last September.

 

Winder turbines under monitoring a thousand miles away

 

Business opportunities are everywhere, but transient.

 

Last May, the State Council officially issued the "Made  in China 2025", a strong impetus to the manufacturing indu≈stry undoubtedly. Promoting the digitization, networking and intelligentization o←f manufacturing has been put on the agenda. Whether en∏couraged by the policy or led by “Internet Plus" fervor, the initial conc<eption of HITE Renewable Energy enabled caught up with the upsurge transforming fro≤m "Made in China" to "Made with Wisdom" right in ti&me.

 

After the first batch of new products came off the☆ assembly line, the assembly plants of HITE Renewable Energy are still busy. Workers responsible f↑or installing and debugging wind turbine converter control s©ystem have one more task to embed a palm-sized netwo≥rk communication adapter in control system of each wind turbine inverter.

 

An assembled wind turbine inverter has the similar shapeφ of a quarto wardrobe. Opening one of the doors, you can see that the motherboard bearingβ the whole control system is clear at a glance and∏ that the network communication adapter is fixed at one corner of the £motherboard.

 

This network communication adapter is referred to as "smart card". The function and role it plays ¥is proportionate to the network adapter embedded in the computer mainframe box.

 

Nowadays, the civil use of network adapter is common. But its industrial use i¥s subject to tight restrictions on access requirement.

 

“Due to the particularity of the place where a wind turbine works, the> reliability and continuity of the whole control system> are strictly required." As far as Ji Jianqiang is conc♠erned, the network adapter embedded in wind turbine inverter is reqΩuired to withstand not only high temperatures, but al∏so the extremely cold weather.

 

This network adapter helps to achieve a bi-directional co↓nnection between human and machines. The biggest benefit is to put the whole wind turbine under fβine management. “Previously, our staff can't carry out regular insp​ections on wind turbine after it is transported to the site for formal operation, except ✔knowing whether it is in normal operation or not.

 

The Internet and Internet of Things link people, produc↓ts and data. The “personal health consultant” ​to wind turbine is also the most responsible "intelligent staff" of the enterprise.

 

Imagine this: every day, data from thousands of wind tφurbines dotted in the vast country is collected and i✔ntegrated. How operation and problems vary under the circumstances of different areas', altitudes and temperatures…... these resu≈lts out of big data analytics can provide design basis and reference for the enterprise to© develop and optimize the next generation of products. It is the next step HITE RenewaΩble Energy will take to set up a monitoring center within the enterp§rise to realize real time and all-weather monitoring of all products.
