| Abstract: | A variable voltage variable frequency(VVVF) control device for beam-pumping unit was developed.It is based on high-power switch IGBT and its input is three-phase AC 380 V,the core of its control circuit is the PWM control IC SA866AE.The SPWM is adopted in the device,its maximum output power is 55 kW,and its frequency of output voltage can be varied continuously at the range of 0~63.5 Hz.The operation and test results of the devices in Shengli oilfield show that the power factor of AC asynchronous motor is up to 0.98 and its energy-saving result of total efficiency achieve 26.58 %,exhibites a good effect on energy saving. |
