A controller control method, device and camera system, the method comprising: obtaining a preliminary value of the reactive power reference value of the controller Q ref1 ;Preliminary value for the reactive power reference value of the rectifier Q ref1 Perform clipping processing to obtain the final value of the reactive power reference value of the condenser Q ref2 ;Get the grid frequency and judge whether the grid frequency is within the frequency dead zone, if not, calculate the initial value of the active power reference value of the condenser according to the grid frequency P ref1 ;Preliminary value for the active power reference value of the rectifier P ref1 Perform clipping processing to obtain the final value of the reference value of the active power of the condenser P ref2 ;Output the final value of the condenser to the reactive power reference value Q ref2 and the final value of the active power reference value of the condenser P ref2 . According to the technical solution of the embodiment of the present invention, the problem of poor stability of the power grid system is solved by adopting the control mode of constant active power and constant reactive power, which not only realizes steady-state voltage regulation, but also provides fast and correct reactive power response, and also controls inertia And FM plays the role of regulation.
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...
