| Popis: | 101 After over ten years of hardship in the development of wind farms in Taiwan, wind farm is still in its infancy, and there are scanty researches by scholars and research institutions. Taiwan has rich wind energy resources; however, the operating efficiency of the developed wind farms is not low. According to the investigation of this study, the comprehensiveness of energy policies, complete wind farm planning, and energy policy implementation should be enhanced. This study first reviewed energy policies of wind farms development in developed countries, such as European countries and the US, as well as emerging countries, such as China. Those policies were compared with the energy polices of Taiwan for analysis, so as to provide references for the policymakers. The operating data of the developed wind farms in Taiwan indicated that the poor operating efficiency is attributed to three factors: low applicability of wind turbines, poor performance of wind farms, and high long-term loss of power transmission and distribution. A preliminary evaluation was conducted on the operating efficiency loss of the wind farms caused by those three factors. The loss of annual power generation due to low applicability of wind turbines was 12%-27%, that due to poor performance was 25%, and that due to long-term loss of power transmission and distribution was 5%. Regarding long-term loss of power transmission and distribution, the traditional transformers can be replaced by high-efficiency transformers to reduce long-term loss by 0.2%. Using a non-amorphous metal transformer can reduce the long-term loss by 0.25%. Increased investment costs can be recovered in 3 years and 7 years, and reduced CO2 emissions are 162 tons and 207 tons within 30-year life cycle. This has economic and environment benefits. Loss caused by applicability of wind turbines depends on government''s autonomy policy for the wind turbine industry, which is a major link of the renewable energy policy. The wind turbine efficiency can be improved by promoting the policy. In this paper, the classification is based on wind farm types and applicability of wind turbines, with the aim to help the wind farm developers and independent wind farm enterprises to select or develop wind turbines suitable for wind farms in Taiwan. For performance improvement of wind farms, Taipower, Infravest and other companies have accumulated ten years of operating experiences. The Institute of Nuclear Energy Research of the Atomic Energy Council, as well as the Green Energy and Environment Research Laboratories of the Industrial Technology Research Institute, has invested wind energy evaluation technology and improvement of accuracy. In continuous improvement and increase of efficiency of wind farm, application of wind energy evaluation technologies to wind farms are summarized in this paper. This is a pioneering study on the improvement of wind farm operating efficiency by reducing long-term loss of power transmission and distribution. The methods of reducing long-term loss of power transmission and distribution to improve wind farm operation efficiency include optimization of cable layout and selection of high-efficiency power transmission and distribution equipment. |
