【摘要】 文章以瞬时无功功率理论为基础,提出一种谐波电流的离散检测方法。该方法用复化积分算法取代传统的低通滤波器[1],具有截止频率特性好,检测结果稳定,易于编程实现等优点。通过对不同检测方法的单位冲击响应进行对比分析,结果表明:该方法比传统的检测方法具有更快的响应速度。实验也验证了该方法的正确性。更多还原

【Abstract】 This paper shows a new discrete method to detect harmonic current base on the Instantaneous reactive power theory. This method use complex integral algorithm instead of common low pass filter, So it has several advantages, such as a better limiting frequency, steadier result and more easy realization by programming. This paper illuminate the new method has a rapider response speed through contrasting with several other detection methods. And several experiments have prove it too. Furthermore, it can be used in the detection of three-phase harmonic voltage.更多还原
