SYSTEM STABILIZATION DEVICE

摘要

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.

主权项

1: A power system stabilizer that issues a control command to a first storage battery among a plurality of first power generators and said first storage battery that are connected to an independent system for power supply via a first tie-line,
the power system stabilizer comprising: a parameter determination unit that obtains a rate-of-change limit value on the basis of operation information that includes information regarding those of said first power generators that are in operation, said rate-of-change limit value indicating a limit to be imposed on a total value of changes in an overall output of said first power generates in operation; and a control block unit that generates a command value to be given to said first storage battery on the basis of an interconnection point power flow value measured on said first tie-line and said rate-of-change limit value obtained by said parameter determination unit, said interconnection point power flow value being a total value of outputs of said first power generators and said first storage battery.
