English term or phrase: frequency Up/Down

(controllo in frequenza unit¨¤ interna di condizionamento)

PI Control (Determine ***Frequency Up/Down*** by ∆D Signal)

1. P control
Calculate a total of the ∆D value in each sampling time (20 seconds), and adjust the
frequency according to its difference from the frequency previously calculated.
2. I control
If the operating frequency is not change more than a certain fixed time, adjust the frequency
up and down according to the ¦²∆D value, obtaining the fixed ¦²∆D value.
When the ¦²∆D value is small...lower the frequency.
When the ¦²∆D value is large...increase the frequency.
3. Limit of frequency variation width
When the difference between input current and input current drooping value is less than 1.5
A, the frequency increase width must be limited.
4. Frequency management when other controls are functioning
When each frequency is drooping;
Frequency management is carried out only when the frequency droops.
