A Phasor Measurement Unit And A Method Of Publishing Current And Voltage Signals As Synchronized Phasor Values
Abstract: The invention relates to an method of integrating IEC 61850 communication protocol with a phasor measurement unit, comprising the steps of time synchronization of the internal clock with 1 PPS signal [312]; accessing wired field data from a plurality of current and voltage transforms as analogue inputs in real-time [321], samples the inputs [322], compute synchrophasors and related parameters as per C 37.118.1 protocol [323], format the message frame and publish C 37.11.2 and RSV packets [324]; polling for the status signals from a switchgear [331] as digital inputs [332], formatting as C 37.11.2 packet [333] for transmission, and processing for transmission as RGOOSE publish messages [334]; subscribing to the RGOOSE messages [344], decrypting the message for binary outputs [343], and activating the corresponding binary output hardware for control action [342] sent to the field switchgear [341]; and time and date synchronization of the internal real-time clock for synchrophasor messages [352] from the PTP server [351]. { FIGURE 3 }
