Abstract

The invention relates to the technical field of measurement data compression transmission of a wire area measurement system (WAMS), in particular to a Beidou short message-based measurement data compression transmission method of the WAMS. The Beidou short message-based measurement data compression transmission method is a Beidou short message-based research method capable of transmitting a largeamount of main data of a power grid in real time. The Beidou short message-based measurement data compression transmission method comprises the steps of compressing and transmitting a byte space of adata frame of monitoring data by a PMU; acquiring on-line monitoring data on the PMU, and decompressing the on-line monitoring data; monitoring a working condition of monitoring end equipment of a monitoring system on line; and remotely configuring a parameter of the monitoring end equipment of the monitoring system. By the Beidou short message-based measurement data compression transmission method, high efficiency of big data transmission can be improved, and high accuracy of a transmission result is improved; and data on the power grid measured by the PMU in a substation is compressed to form a binary code, the binary code is sent to a Beidou short message server by a communication system, program decoding decompression is performed in a control center after receiving of a satellite navigation system, real-time monitoring of the power grid is finally achieved, and real-time data detection of the PMU during normal running of a power system is ensured.
