| Abstract: | Introduction was made to the composition of electrical energy measurement and design principle of digital substation. The substation adopted the electricity energy measurement of analog quantity sampling value transmission technology based on IEC 61850 standard, digital signal processing technology and electricity energy management technology based on communications service reflection. Error comparison was carried out between traditional substations and digital ones. The result shows that the correctness of... |
