More Information
Summary:An SC includes a determination database storing determination data. The SC includes a specific-event-occurrence detection unit that detects an occurrence of a transformer substation specific event, a data-compression-instruction output unit, a specific-event-recovery detection unit that detects an end of the specific event, and a data-compression-termination-instruction output unit. An MU and an IED each include a data compression flag setting unit and a data compression unit. The data compression flag setting unit sets a data compression flag to be ON when the MU and the IED receive a data compression instruction, and sets the data compression flag to be OFF when the MU and the IED receive a data compression termination instruction. The data compression unit starts a compression of received data when the data compression flag is ON and terminates the compression of the received data when the data compression flag is OFF.
