Abstract：To balance the reactive power demand and power quality of offshore wind farms, the traditional static var generator (SVG) and the active power filters (APF) can be integrated into a new type of integrated static var generation and filtering device. Based on the actual power quality testing of an existing offshore wind farm, this paper proposes a method for analyzing the parameter selection of key components, including the capacity and voltage level of the APF valve bank, as well as the capacity, voltage level, and short-circuit impedance of the transformer. After calculating the relevant parameters of this integrated device using the proposed method, a simulation model is established. The results show that the harmonic current can be limited to the allowable range and the device can simultaneously meet the reactive power compensation requirements. It can thus be concluded that replacing traditional SVGs and APFs with this integrated static var generation and filtering device is feasible.
