Taiwan First Large-Scale Offshore Wind Farm Connection - A Real Project Case Study

Abstract

The west coast and islands of Taiwan have abundant wind resource, which offers a great opportunity for large-scale offshore wind power generation. In Taiwan, the first stage of offshore wind farms at Jhang-Bin and Peng-Hu areas have been planning. Particularly, the Jhang-Bin wind farm would become the first and one of the largest wind farms in Taiwan. Therefore, its impacts on the system operation and security have to be investigated and studied in advance. Following a general connection design discussion, this paper comprises four major system impact analyses: load flow, fault current, voltage variation, and transient stability. Moreover, three types of typical wind turbines have been adopted respectively in this study in order to compare their performances on the wind farm integration system. From the simulation results, some significant conclusions and recommendations have been extracted, which would contribute to the first off-shore wind farm development in Taiwan.
