Supply Chain (Value Chain)
¥
<3>Wind Turbine Manufacturers play crucial role: downstream to ensure the operation efficiency of turbine and smooth power input to grid; upstream to drag technically complete supply chain.
� TSO (Transmission System Operator) in China
<0> Consumer
- Power supply for 17.8% population
- 1 million km2
- Power supply for 82.2%population
- Cover 88% of China territory
<1> Grid Company
Though <3>Wind Turbine Manufacturers play crucial role, the requirements come from downstream<1> Grid Company . Experiencing years of reform in China, so far there are 2 TSOs with “company”legal entity, which however used to be subordinates of “administrative ministry”.

� National Norm for WF Grid Integration in Revision
Recap of this NormRecap of this Norm:
1) Max. active power variation is regulated;
2) Reactive power is required as well as relevant requests therein;
3) WF Voltage range and LVRT required;
4) WF Frequency variation range in operation and for short term;
5) Power quality requests for voltage fluctuation, flicker and harmonics.
6) Testing report for grid integration
Since most of wind farms are located in State Grid area, GB/Z 19963:2005 “Technical rule for connecting wind farm to power network” is compiled with its influence, which is in revision and expected to be implemented in 2010 upgrading to GB/T. (GB = Guo Biao: meaning National Norm; Z = Guideline / T = Recommendation)
� WF Mostly Invested by “Big 5” in Remote Area
<2> Wind Farm <1> Grid Company
<0> Consumer
China “Big 5”invested WF capacity accounts for ca. 50%.
Power generation has been commercialized for years in China, at present over 50% electricity is generated by “State Corporations” with conventional fossil fuel e.g. coal, as well as for wind. Wind resource is analyzed based on climatic data, Wind Farms are mainly in remote area.
WF is relatively “clustered” in remote area of China, where wind resource is “believed” strong. Unclear is “micro-siting ” done or not.
� State-of-the-art Wind Measure & WF Planning Needed
Resource Measure & Wind-farm Plan
Concurrently there are no revised national standards for wind resource analysis and wind farm planning. The existing standards in GB/T was back to 2002; Co-existing are some standards in “ministry level”, latest ones were in 2007. (DL = Dian Li : meaning Electricity Ministry, which not exists any more after reform)
GB/T 18709-2002 Methodology of wind energy resource measurement for wind farmGB/T 18710-2002 Methodology of wind energy resource assessment f or wind farm
DL/T 5067-1996 Code on compiling feasibility study report of wind power projectsDL/T 5191-2004 Code of construction acceptance on wind power plant projectDL/T 51383-2007 Technical specification of wind power plant designDL/T 5384-2007 Specification for construction management and design of wind power project
Regarding China as big market for wind energy and CDM, technical companies in developed countries are seeking chances incl. with software likeWAsP, WindSim, Windfarmer, Windpro etc.
Chinese government organizes revision for relevant standards, meanwhile sets up national program “863” to promote scientific R&D involving top universities in China like Tsinghua.

� Lesson Learnt – MW Installed vs. Grid Integration
Due to severely unbalance between WF and intake capability of local grid, this “bottle-neck” is de facto hindering sustainable and healthy development of wind industry.

??
In China, policy weighs!!! Looking back – insufficient coordination among different governmental sectors since 2005 makes actual “grid-ding” severely hampered so far. One of these overlooks: “Grid Integration” rule comes into force late .
� Wind Turbine Manufacturer? Assembler?
<3> Wind Turbine <2> Wind Farm <1> Grid Company
<0> Consumer
In 5 continuous “great leap” from 2005-09, both market demand and capital operation created a superficial “prosperous” in WF MW installation. Besides mentioned grid integration issue, <3> wind turbine manufacturers are somehow “assembler” with purchased “technology-transfer”.
Almost behind each “big” Chinese WTG mfg’er , there stand 1 or more “technology-transfer” company from Europe:Sinovel – Fuhrlaender, WindtecGoldwind – Jacobs, VensysDong Fang – Repower, GHMing Yang – AerodynUP – Aerodyn via. Ming YangWindey – with support from GH…
Technology developed Chinese R&D “program 863” by SUT has been “transferred”many times to “assemblers”.
In pursue of pure MW installation promoted by central & local government, there suddenly appear >80 WTG “maker” in 5 years!
Role of <3>Wind Turbine Manufacturers: downstream to ensure the operation efficiency of turbine and smooth power input to grid; upstream to drag technically complete supply chain…
Improving !
� National Standards Updating & Harmonization Needed
Updating and Harmonization of standards for “Wind Industry” is undergoing, while existing standards are 1) outdated; 2) scattered in different industry sectors; 3) lack of authority. (GB = Guo Biao: meaning National Norm; JB = Jixie Biaozhun: meaning machinery industry standard; DL = Dian Li : meaning Electricity Ministry, which not exists any more after reform)
GB 18451.1-2001 Wind turbine generator systems - Safety requirements (IEC 61400-1:1999 identical)GB/T 18451.2-2003 Wind turbine generator systems - Power performance test (IEC 61400-12:1998 identical)GB/T 20320-2006 Measurement and assessment of power quality characteristics of wind turbine generator system
(IEC61400-21:2001 identical)
Except for rotor blade (aerodynamic + composite material industry), not only GB, for machinery, also JB; for WF, electricity sys., also DL; for WF project infrastructure, foundation designing etc, CPECC/Hydro-china Corp takes role
Construction relevant codes, rules and standards
SAC TC50 is corresponding to IEC61400 TC 88

Unfortunately healthy and sustainable “close-loop”mechanism has not been set up.
In this 5-year “great leap”, everything was “purchased” (or invested) with aim to quick return, therefore: 1) technology was bought, 2) supply chain was in inflation due to large amount of capital rush-in.For healthy and sustainable development, Chinese wind industry is in “re-engineering”.

� Commercialized Component / Material Production
As to the present “surplus” supply in China, it is estimated that besides industrial “re-engineering” in 2010-2012 for domestic market, some wind turbine mfg’ers, but component/material suppliers in particular, are seeking market outside China.
The upstream sectors of wind industry in China have been much more “commercialized” than downstream ones.
These suppliers are gradually upgrading their production level with criteria required by their clients from developed countries, since global technical leading company, Vestas, GE wind, Gamesa etc. have set up production facilities and started out-sourcing from China.
With initiative to prepare for entering international market for long run, these suppliers implement directly EN, IEC etc. standards in production, process and testing, even there are relevant GB standards available.
