The development of offshore wind power is a crucial step in China’s energy transition and the achievement of carbon peaking and carbon neutrality goals. This paper first introduces a wireless communication technology for independent networking. Its applicability in the field of relay protection is analyzed, and a security encryption scheme for its use in relay protection services is designed. Considering the primary wiring form and protection function configuration of offshore wind power, a multi-terminal wireless differential protection method suitable for offshore wind power collection lines is proposed, achieving synchronization error less than 3° and typical delay of wireless self-organizing network communication less than 12ms. Utilizing multi-terminal data synchronization technology and differential protection algorithms, a scheme for fault isolation and recovery of non-faulty wind turbines is established, thereby achieving minimal range isolation of offshore wind power collection line faults and precise fault section location. The action time of multi-terminal differential protection is less than 40ms. Finally, experimental results confirm that this technology’s various metrics satisfy the demands of engineering applications and hold promotional value, offering a reference for the practical application of wireless communication technology in offshore wind power collection line protection services. |
