| 摘 要： | 针对交流电力的有功功率,首先探讨了参数定义测试法,进而基于相关性原理并结合工程实际详细地研究了功率定义测试法,提出了它固有的抗干扰特性,然后分析并比较了两种测试方法的测试性能。实验表明,相对于参数定义测试法,功率定义测试法可减少2倍多的用于分析的采样点数,干扰幅值的要求从小于信号幅值的3%可放宽到信号幅值的12%。

| Abstract: | For active power of AC power,parameterized-definition test method is discussed.The approach for testing the active power according to power definition in engineering application is researched based on correlation analysis theory in detail and its inherent antinoise characteristic is proposed.Test performances of the two approaches are analyzed and compared.Experiment results show that compared with the parameterized test method,the approach based on the definition of active power can reduce number of the sa... |
