In this case it is found that the RF energy is transferred to the beam at a constant rate regardless of the local signal amplitude. Thus if the device is designed of the correct length then all the power is transferred. H. 5. The travelling-wave convertor with distributed DC retardation. ratio between the beam current and the input power level. Both these problems can be overcome by special design and by proper control but are accepted disadvantages. It is also necessary that the DC retarding field is not uniform because its amplitude follows that of the attenuating RF field.

In principle all the system parameters can be identified in this manner. In practise this would involve excessive computer time and a combination of test methods and parameter estimation techniques has been adopted. Test methods are designed so as to identify the role of particular parameters having eliminated others. Determination of Wind Turbine Generator Parameters Conventional test procedures involve driving the generator at synchronous speed. In the case of the wind turbine generator this was impracticable due to the requirement for high torque at low speed in addition to the inaccessibility of the shaft.
