The invention discloses a phase modifier control method, a phase modifier control device and a phase modifier system. The method comprises: acquiring a direct-current side voltage Edc and an alternating-current side reactive power Qg of a converter in the phase modifier system; judging whether the direct-current side voltage Edc of the converter is in a voltage dead zone or not; if not, obtaininga d-axis current reference value of the converter through calculation and amplitude limiting; if so, taking a previous value of the d-axis current reference value of the converter as the d-axis current reference value of the converter; calculating to obtain an initial value Igqref1 of a q-axis current reference value of the converter according to the alternating-current side reactive power Qg of the converter; performing amplitude limiting on the preliminary value Igqref1 of the q-axis current reference value of the converter, and obtaining a final value Igqref2 of the q-axis current referencevalue of the converter; and outputting a final value Igqref2 of the d-axis current reference value and the q-axis current reference value of the converter, wherein the final value Igqref2 of the d-axis current reference value and the q-axis current reference value of the converter is used for controlling the phase modifier. According to the embodiment of the invention, voltage, inertia and frequency adjustments are realized.
Description
technical field [0001] The present invention relates to the field of camera controllers, in particular, to a camera controller control method, device, camera controller system and storage medium. Background technique [0002] The condenser, as a reactive power compensation device, can automatically increase the reactive power output when the grid voltage drops and absorb reactive power when the grid voltage rises to maintain the voltage and improve the stability of the power system according to the needs of the system. Improve the quality of system power supply, so it is widely used in UHV DC converter stations. [0003] At present, the existing controllers all use synchronous motors, which have problems such as uncontrollable inertial support and inability to participate in the primary frequency regulation of the system during operation, making them suitable for many application scenarios, especially those with complex power grid operating characteristics (such as New ener...
