(3) ”4 PowerContr” menu: relative functions of active, reactive power control

and over-frequency derating, including “ActiveContr(%)”, “RePowerContr”

and ”FreqDeratCtrl” menus.

1. “ActiveContr(%)” menu: adjust the active power of AC output, the

range is 0~100.0%.

2. “RePowerContr” menu: set up the reactive power control mode,

including 6 submenus: “1. None”, “2. Dispatch”, “3. Q Set”, “4. PF Set”, “5.

PF(P) Set” and “6. Q(U) Set”.
