| 摘 要： | 提出了一种基于软件滤波实现计算基波功率的方法,理论上论证了单纯对电压通道滤波后计算基波功率的合理性,通过相位校准算法对滤波造成的相位差进行补偿,最终实现对基波功率的高精度测量。软件仿真结果及样机精度试验数据表明,该方法计算基波功率简单,且准确度较高。

| Abstract: | A new calculation method of fundamental wave power based on software filtering was poposed.The rationality of the calculation fundamental power after purely filtering voltage channels was verified theoretically.The phase difference resulted from filtering was compensated through phrase alignment algorism.A high precision measurement for fundamental power was realized.Both the Simulation and the test results of prototype demonstrated that the proposed new measurement method was simple to realize with high de... |
