Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 変動する外気温度においても、同期発電機の 過負荷を防止するとともに高効率にて発電設備の自動運 転が可能なガスタービン発電設備の制御装置26を得るこ とにある。 【構成】 ガスタービン13と直結された同期発電機11の 運転出力を検出する発電機出力演算装置21と、同期発電 機11機内を冷却する冷媒の温度を検出する冷媒温度測定 装置23と、この冷媒温度測定装置23により得られた冷媒 温度に基づいて同期発電機11の出力限界値を演算する出 力限界演算装置24と、発電機出力演算装置21により得ら れた同期発電機11の運転出力が出力限界演算装置24によ り得られた出力限界値を越えたときは同期発電機11を出 力限界値内で運転させる出力調整装置25とを備えたこと を特徴とする。 (57) [Abstract] [Purpose] To obtain a control device 26 for a gas turbine power generation facility that can prevent overloading of a synchronous generator and can automatically operate a power generation facility with high efficiency even when the outside air temperature fluctuates. is there. [Arrangement] A generator output arithmetic unit 21 for detecting an operation output of a synchronous generator 11 directly connected to a gas turbine 13, a refrigerant temperature measuring unit 23 for detecting a temperature of a refrigerant for cooling the inside of the synchronous generator 11, and The output limit calculation device 24 for calculating the output limit value of the synchronous generator 11 based on the refrigerant temperature obtained by the refrigerant temperature measuring device 23, and the operation output of the synchronous generator 11 obtained by the generator output calculation device 21. And an output adjusting device 25 for operating the synchronous generator 11 within the output limit value when the output limit value obtained by the output limit calculating device 24 is exceeded.
