    • A valve fault test system is disclosed. The system tests for leakage in a valve within a turbine system having a gas turbine and a steam turbine sharing a common shaft, by performing actions including: placing the gas turbine in a control mode; determining a power output for the steam turbine corresponding to the control mode of the gas turbine; preventing steam flow to the steam turbine by providing instructions to close at least one of a steam turbine control valve or a steam turbine stop valve; determining a power output for the steam turbine corresponding to the steam flow being prevented to the steam turbine; and comparing the power output for the steam turbine corresponding to the closed at least one of the control valve or the stop valve to an expected power output for the steam turbine to determine whether a leakage in the valve exceeds a predetermined threshold.
    • 公开了一种阀故障测试系统。 该系统通过执行包括将燃气轮机置于控制模式的动作来测试具有燃气轮机和共用公共轴的蒸汽轮机的涡轮机系统内的阀的泄漏; 确定对应于燃气轮机的控制模式的蒸汽轮机的功率输出; 通过提供关闭蒸汽轮机控制阀或汽轮机截止阀中的至少一个的指令来防止蒸汽流向蒸汽轮机; 确定对应于蒸汽涡轮机的蒸汽轮机的功率输出被阻止到蒸汽轮机; 以及将与所述关闭的所述控制阀或所述截止阀中的至少一个所述关闭的所述汽轮机的功率输出与所述汽轮机的预期功率输出进行比较,以确定所述阀中的泄漏是否超过预定阈值。
