| 摘 要： | 在相角测量的相关分析法的基础上,对相关分析法进行了改进,提出了双相关分析法。通过实验,分析算法对相角测量精度的影响。与一般相关分析算法相比,双相关算法降低了采集随机性误差,而且克服了选取参考信号时带来的相位误差,具有测量精度高、抗干扰能力强等优点,借助于通信网络,可以实现电力系统相角的实时测量。

| Abstract: | Correlation analysis is applied in phase difference measurement.Correlation analysis is improved,and a sort of new method is brought forward on double correlation analysis.By experiment,the measuring error is analyzed.Compared with traditional way,gather random error is reduced,and referral signal error is overcomed.The double correlation analysis has the advantages of exactitude,speedy and anti-jamming,in virtue of computer communications network,the phase difference real-time measurement is realized. |
