  • Patent number: 9640999
    Abstract: A technique with which a change in power frequency can be suppressed. A power system stabilizer issues a control command to a first storage battery among a plurality of first power generators and the first storage battery that are connected to an isolated island system via a first tie-line. The power system stabilizer includes a parameter determination unit and a control block unit. The parameter determination unit obtains, on the basis of operation information, a rate-of-change limit value that indicates a limit to be imposed on a total value of changes in the overall output of first power generators in operation. The control block unit generates a command value to be given to the first storage battery on the basis of an interconnection point power flow value measured on the first tie-line and the rate-of-change limit value obtained by the parameter determination unit.

  • Publication number: 20160221476
    Abstract: In a case where an engagement member is assembled on an upper rail, a second rotary shaft portion is inserted to a shaft receiving bore of a first side wall portion from an inner side of an upper rail. After the insertion, the engagement member is rotated so that the second rotary shaft portion is inserted to the shaft receiving bore of the second side wall portion. At this time, because a shaft allowable length is specified to be greater than a shaft maximum rotation length, an interruption of an insertion of the rotary shaft portion because of a contact of the second rotary shaft portion with an edge portion of the shaft receiving bore at the second side wall portion is restrained.
