Embodiment Construction
[0020] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] The rated output current of the active power filter in this embodiment is 60A, the target temperature value of the power device is 90°C, and the target temperature value of the reactor is 120°C.
[0022] The specific implementation steps are as follows:
[0023] In the first step, according to the rated compensation current 60A of the active power filter, set 4 fan speed regulation gears.
[0024] In the second step, the rated compensation current 60A of the active power filter is used as the output current of the fourth gear, and the current of the other three gears is calculated by dividing the rated compensation current by the product of the gear number and the gear value , were obtained: 15A, 30A, 45A.
[0025] The third step is to determine the reference speed of the gear with the output current of 60A. As shown in Table 1, af...
