  • Patent number: 12191661
    Abstract: 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.

  • Patent number: 11296927
    Abstract: 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.

  • Publication number: 20170010014
    Abstract: An air conditioner test operation application which allows to input control inputs for test operation of an air conditioner from a mobile terminal. Through input of a prescribed control input to a control input unit of the mobile terminal, model information pertaining to units that belong to a prescribed group to undergo test operation is not displayed on the display unit of the mobile terminal by the controller of the mobile terminal, whereas model information pertaining to the other group is displayed; and through input of a display switching control input to the control input unit of the mobile terminal, the model information pertaining to the other group that was not being displayed is displayed on the display unit of the mobile terminal by the controller of the mobile terminal, whereas the model information pertaining to the one group that was being displayed ceases to be displayed.

  • Publication number: 20100306855
    Abstract: Having received an addition notification of a piece of download content, a content processing apparatus registers the notified content as a piece of download-scheduled content. The apparatus recalculates the priority rank of the download execution by taking into consideration a change in the license information on each piece of content, including a piece of already-preregistered download-scheduled content and a piece of content whose download is underway at present. If the download-execution target content specified by the recalculated priority rank is different from the content whose download is underway at present, the apparatus changes the download-execution target to the content specified by the priority rank.
