Abstract
The entire wind farm is regarded as a large-capacity wind turbine for modeling double-fed wind farm. The influence of flow field characteristics in the wind farm has been ignored. In order to reflect the influence in double-fed wind farm equivalent modeling, an equivalent modeling method of double-fed wind farm based on the flow field characteristics has been proposed. A calculation model of the double-fed wind farm flow field has been built considering the influence of terrain and wake. The wind speed was calculated at each wind turbine installed point based on the flow field calculation model, and using the wind speed as the input wind speed for each wind turbine, the dynamic characteristics of the wind farm production process has been studied. The simulation analysis has been done for the proposed modeling method, and the simulation results show that the proposed modeling method can reflects the dynamic characteristics of the wind farm production process more accurately.
期刊介绍：
We would like to inform you, that iJOE, the ''International Journal of Online Engineering'' will accept now also papers in the field of Biomedical Engineering and e-Health''. iJOE will therefore be published from January 2019 as the ''International Journal of Online and Biomedical Engineering''. The objective of the journal is to publish and discuss fundamentals, applications and experiences in the fields of Online Engineering (remote engineering, virtual instrumentation and online simulations, etc) and Biomedical Engineering/e-Health. The use of cyber-physical systems, virtual and remote controlled devices and remote laboratories are the directions for advanced teleworking/e-working environments. In general, online engineering is a future trend in engineering and science. Due to the growing complexity of engineering tasks, more and more specialized and expensive equipment as well as software tools and simulators, shortage of highly qualified staff, and the demands of globalization and collaboration activities, it become essential to utilize cyber cloud technologies to maximize the use of engineering resources. Online engineering is the way to address these issues. Considering these, one focus of the International Journal of Online and Biomedical Engineering is to provide a platform to publish fundamentals, applications and experiences in the field of Online Engineering, for example: Remote Engineering Internet of Things Cyber-physical Systems Digital Twins Industry 4.0 Virtual Instrumentation. An important application field of online engineering tools and principles are Biomedical Engineering / e-Health. Topics we are interested to publish are: Automation Technology for Medical Applications Big Data in Medicine Biomedical Devices Biosensors Biosignal Processing Clinical Informatics Computational Neuroscience Computer-Aided Surgery.
