发电系统及发电系统的控制方法
摘要：
本发明提供一种可防止供给于蒸汽利用设备的蒸汽压力暂时脱离容许压力范围而降低的发电系统及发电系统的控制方法。在该发电系统(20)中，当导入的蒸汽流量比规定流量多时，发电装置(32)基于排出压力传感器(30)的检测压力来控制通过该发电装置(32)的蒸汽流量，使该发电装置(32)的下游侧的蒸汽压成为比设于主配管(14)的减压阀(16)的第一设定压高的第二设定压，另一方面，当导入的蒸汽流量降低到所述规定流量时，基于所述排出压力传感器(30)的检测压力来控制通过该发电装置(32)的蒸汽流量，使该发电装置(32)的下游侧的蒸汽压成为比减压阀(16)的第一设定压低且比0kPaG高的第三设定压。
摘要（英）：

The present invention provides a power generation system capable of preventing steam pressure supplied to steam utilization apparatus from temporary deviation from allowed pressure range to be reduced, and a control method for the power generation system. In the system (20), when supplied steam flux is more than predetermined flux, the power generation device (32) controls steam flux through the power generation device (32) based on detected pressure of a discharge pressure sensor (30), such that stream pressure of downstream side of the power generator device (32) becomes a second setting pressure higher than a first setting pressure of a decompression valve (16) arranged on a main tubing (14), in another aspect, when supplied steam flux is less than predetermined flux, the power generation device (32) controls steam flux through the power generation device (32) based on detected pressure of a discharge pressure sensor (30), such that stream pressure of downstream side of the power generator device (32) becomes a third setting pressure lower than a first setting pressure of a decompression valve (16) and higher than 0 kPaG.
