The invention relates to a resonance suppression method and device in a flexible direct current control system, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring an active power reference value and a reactive power reference value of the flexible direct current control system; acquiring current reference values on different axes in the flexible direct current control system according to the active power reference value and the reactive power reference value; when it is judged that resonance occurs according to the frequency of harmonic waves in the flexible DC control system, determining a resonance suppression strategy according to the resonant frequency, and obtaining a filtering voltage value corresponding to the determined resonance suppression strategy; obtaining voltage reference values on different axes according to the current reference values on the different axes in the flexible direct current control system and the filtering vol
