8. the propagation of error method of a full digital electric power observation and control equipment, be characterised in that: the propagation of error method of this full digital electric power observation and control equipment adopts the error verification device of full digital electric power observation and control equipment complete or realize, namely the modulus type standard power measuring and controlling equipment of the error verification device of full digital electric power observation and control equipment and accredited full digital electric power observation and control equipment is adopted to complete or realize, the signal processing module of described modulus type standard power measuring and controlling equipment reads the primary voltage and current digital amount information that are stored in orderly framing in power supply and control information memory module when it is upwards traced to the source again, calculating is re-started to it, process, complete the metering to observing and controlling information, and exported by its observing and controlling message output module and meet digital stream that various high-rise standard digital communication stipulations comprise measured observing and controlling information to the electric power observation and control parameter error comparer meeting various high-rise standard digital communication stipulations and comprise the digital stream input interface of observing and controlling information, meet comprising with the digital stream of the voltage and current digital information of measured observing and controlling information equivalent to accredited full digital electric power observation and control equipment of specific low layer standard digital communication stipulations by the output of its digital communications module simultaneously, the digital stream comprising primary voltage and current digital amount information meeting specific low layer standard digital communication stipulations that this accredited full digital electric power observation and control equipment is exported by its interface circuit input modulus type standard power measuring and controlling equipment, calculate through himself, process, complete the metering of observing and controlling information and exported by its interface circuit and meet digital stream that various high-rise standard digital communication stipulations comprise measured observing and controlling information to the electric power observation and control parameter error comparer meeting various high-rise standard digital communication stipulations and comprise the digital stream input interface of observing and controlling information, through comparing two-way observing and controlling information with meeting the electric power observation and control parameter error comparer that various high-rise standard digital communication stipulations comprise the digital stream input interface of observing and controlling information, draw the difference of the observing and controlling information that the modulus type standard power measuring and controlling equipment of the error verification device of full digital electric power observation and control equipment measures and the observing and controlling information that accredited full digital electric power observation and control equipment measures, simultaneously the signal processing module of modulus type standard power measuring and controlling equipment is by observing and controlling information error value when being stored in upwards tracing to the source in power supply and control information memory module and subtracting each other by with meeting the current observing and controlling information error value tape symbol that parameters of electric power error comparator that various high-rise standard digital communication stipulations comprise the digital stream input interface of observing and controlling information exports of inputting from its error in dipping value input interface, error between conventional criteria electric power observation and control equipment more high-grade when can draw accredited full digital electric power observation and control equipment and upwards trace to the source, namely the error testing to accredited full digital electric power observation and control equipment is realized, that is the error going down realizing or complete accredited full digital electric power observation and control equipment, for there being display panel, be with or without the accredited full digital electric power observation and control equipment of high-rise standard digital communication stipulations interface, also the parameters of electric power error comparator with meeting various high-rise standard digital communication stipulations and comprise the digital stream input interface of observing and controlling information can be dispensed, and directly the various electric power observation and control information that modulus type standard power measuring and controlling equipment display panel shows and the corresponding various electric power observation and control information shown on accredited full digital electric power observation and control equipment display panel are carried out real time contrast, and be stored in store in the power supply of modulus type standard power measuring and controlling equipment and control information memory module upwards trace to the source time corresponding various electric power observation and control information error in dipping tape symbol subtract each other, thus draw the measuring error of the various electric power observation and control information between tested full digital electric power observation and control equipment and more high-grade conventional criteria electric power observation and control equipment, complete error going down.
