This application relates to a control method for parallel operation of an energy storage converter and a generator set to withstand impact loads. The method includes: establishing a control framework for the energy storage converter based on the circuit topology of the energy storage converter and a rotating coordinate system DQ-axis voltage-current control method; connecting a voltage and frequency error droop loop in parallel to the current setpoint of the phase-locked loop current-source inverter within the energy storage converter control framework; and controlling the operation of the energy storage converter after the current loop using an SVPWM modulation strategy. This application achieves stable operation of the energy storage converter and the system, ensuring that when the system starts up with wind turbine-type impact loads, the converter participates in the stable control of the AC bus, dynamically and evenly distributes the impact current, enabling smooth load startup and operation; and dynamically adjusts the power of the energy storage converter in steady state, allowing the diesel generator set to operate at economical power.

The application discloses a kind of radio frequency signal source output power control method, the method includes: the output power range of standard radio frequency signal source and the numerical control attenuation range of numerical control attenuator are divided to obtain multiple control regions, the boundary point of each control region corresponds an output power, a frequency and a numerical control attenuation quantity;Each control region is constructed standard corresponding relationship based on the numerical control attenuation quantity corresponding to the voltage control attenuator;Based on the standard corresponding relationship, target frequency and target power, control the radio frequency signal source to be controlled, can accurately control the power required by radio frequency signal source output, avoid the larger error of output power.
