| 摘 要： | 针对采油平台电网谐波检测和补偿的不足,提出基于瞬时无功功率理论的检测方法,并对该方法进行分析。仿真和试验证明,该检测法不仅动态响应速度快,而且精度好。对于补偿控制策略,建立了并联型三相三线制有源电力滤波器的数学模型,对空间电压矢量PWM控制基本原理进行研究。仿真和样机结果表明,基于空间电压矢量PWM技术的补偿电流控制方法的补偿效果最佳。

| Abstract: | In order to meet the demand of harmonic current detection and compensation of active power filter(APF) in power system of oil production platform,the harmonic current detection method based on the instantaneous reactive power theory was proposed and analyzed.The simulation and experiment show that this detection method not only has fast dynamic response speed,but also has very good accuracy.For the compensation control strategy of APF,a mathematical model of the three-phase three-wire parallel APF was built and then the basic PWM control principles of the space voltage vector were studied.The simulation and prototype experimental results show that the space voltage vector PWM control strategy has the best compensation effect. |
