Disclosed is a system for supporting creation of a system plan to change a configuration of a power system including a power transmission system and a power distribution system. The system stores information on a configuration of the power transmission system and information on a configuration and a load of the power distribution system. The system determines, based on the information on the configuration and the load of the power distribution system, a load accommodation capacity between power distribution substations which indicates a power supply capacity allowed to be compensated for between the power distribution substations through a configuration change of the power distribution system. The system creates a system plan proposal including a change in system configuration of the power transmission system and the power distribution system based on the load accommodation capacity. The system outputs information on the system plan proposal to an output device.

Provided is an apparatus for integrating log that integrates logs in a series including a plurality of instruments each generating a log. The series includes: a log acquisition section that collects a plurality of logs from the plurality of instruments; a message ID time stamp processing section; a time stamp adjustment processing section; and a time stamp orders-of-sending-and-receiving confirmation processing section that confirms whether time reversal is present in the time stamps of the sending/receiving pair of the broadcast messages having the identical message ID in the plurality of time-base-adjusted logs. The time stamp adjustment processing section adjusts the time bases of the plurality of logs in such a manner as to resolve the time reversal in a case of presence of the time reversal in the time stamps of the sending/receiving pair of the broadcast messages.
