Using 10KV power supply is no problem! The usual starting method is an LCI frequency converter, with a capacity of around 4500 KW; manufacturers include SIEMENS, ABB, TOSHIBA, and others!
Calculate based on the minimum short-circuit capacity of the power grid; it is best to start directly. If that doesn’t work, consider using a reactor for voltage reduction or an autotransformer for voltage reduction. These are usually included in the design manuals. Variable-frequency starting is used only when all other calculation methods fail. Variable-frequency starting is expensive and the control is complex. Moreover, large units generally start only once per maintenance cycle. If an inverter is left unused for a long time, it requires proper maintenance; otherwise it will break down when needed.
