The invention discloses a method for measuring the accuracy of digital quantity messages, comprising: a time synchronization device, a digital source to be measured, a protocol conversion device, a program-controlled power source, a voltage divider or a shunt, a high-precision multimeter, a switch and a server ; Output clock synchronization signals to multiple devices through the time synchronization device, and the digital source to be measured triggers the digital source to output a digital message in compliance with the IEC61850-9-2 standard after receiving the clock synchronization signal; the programmable power source receives the clock synchronization trigger After the signal is output, the set analog quantity is output. By comparing the standard digital quantity message with the measured digital quantity message, the ratio error and phase error of the output message of the tested digital source are obtained, so as to determine the accuracy of the measured digital source. , which makes up for the industry gap in the measurement method of the accuracy of the digital message output by the digital source.
Description
technical field [0001] This application relates to the field of digital metrology, in particular to a method for measuring the accuracy of digital quantity messages.
