The phrase "allowable frequency of" is correct and usable in written English.
It can be used in contexts where you are discussing limits or permitted rates of occurrence for something, such as in scientific or technical writing.
Example: "The allowable frequency of the signal must be maintained to ensure optimal performance."
Alternatives: "permissible rate of" or "acceptable frequency of".
When the deviation of the actual load power from the predicted value is 7.875 MW, the power balance is achieved on the condition of the allowable frequency deviation of 0.035 Hz, and ±7.175 MW spinning reserve is assigned due to accounting for the participation of loads in response to the frequency deviation.
According to the DVB-S specification [29], the maximum allowable frequency drift of the generated carrier is 5 MHz [32].
Figure 3 shows the maximum allowable frequency increment as a function of the number of array elements, M. Since Eq. (9) is just an empirical phase requirement, the high offsets shown in Fig. 2 cannot be used in practice due to bandwidth constraints.
In this formulation the allowable frequency deviation and the possible load or renewable generation curtailments are expressed in terms of variable uncertainty sets.
The allowable frequency variation range is ±0.04 Hz; ③ robust economic dispatch (RED), viz., the proposed FARED method with the system frequency fixed to the nominal value; ④ the proposed FARED method with the allowable frequency variation range of ±0.04 Hz.
We will evaluate the maximum allowable frequency offset in Section 5 by simulation.
These values correspond to the minimum frequency of the lowest allowable SW modes propagating through the respective waveguides.
The objective function is taken as the weight of the structure, and constraints consist of the slenderness of compression members, the maximum allowable drift of the structure and the natural frequency of the structure.
It is shown that the maximum power output density only depends on the maximum allowable stress of the beam and the working frequency of the device, and these two factors can be obtained by adjusting the geometry of piezoelectric layers.
