Reactive Power Optimization Analysis of HVDC Converter Station Based on RTDS Simulation

Comparing voltage and reactive power exchange before and after reactive power optimization, the effect of reactive power optimization of converter station is verified. This article presents reactive power balance method of converter station on account of reactive power compensation equipment at low voltage side of main transformer, and proposes a strategy of changing reactive power control region. Taking one local converter station as an example, the real operation condition is simulated in RTDS, and the two proposed methods are applied to reactive power control. The simulation results verify the beneficial effect of the proposed methods on optimizing the switching of reactive power equipment and improving the voltage control ability of converter station. It provides important reference for engineering application of reactive power control strategies optimization.
