针对游梁式抽油机电动机运行过程中功率因数低、对电网波动大的状况,应用电容器分时投切无功补偿技术,采用C8051F系列单片机,配合交流采样方法,软、硬件结合构成无功补偿系统装置。实验波形和实验结果分析表明,系统实现了提高网侧功率因数、降低损耗及节约电能的目的。 Aiming at the low power factor and large fluctuation of the power grid during the operation of the beam pumping unit motor, the capacitors were switched on and off by reactive power compensation technique. C8051F series single chip microcomputer was used. With AC sampling method, the combination of software and hardware Compensation system installation. Experimental waveforms and experimental results show that the system achieves the goal of improving the network side power factor, reducing the loss and saving power.
