Abstract: The substation is a crucial component of the entire wind farm, and the reliability and accuracy of its data are of utmost importance. The successful implementation of the 1 GW wind power project and its snpporting 500 kV grid connection project in Uzbekistan, both in terms of scale and technical complexity. By studying the configuration of the SCADA system in Uzbekistan’s wind power substation, we can gain an in-depth understanding of the SCADA network architecture with local characteristics, as well as optimize its configuration to meet user requirements for cyber-security and applications based on the external network. It is beneficial for us to familiarize ourselves with the local grid company requirements and accumulate experience in the related power projects in Uzbekistan, so as to perfect and improve our own technical level.
