改善燃气轮机系统中的停机吹扫流的系统及机器可读介质
摘要：
本实用新型涉及改善燃气轮机系统中的停机吹扫流的系统及机器可读介质。一种系统包括发电系统的控制器(36)，其包括储存指令的存储器(38)和执行指令的处理器(42)。指令促使控制器(36)控制发电系统以在燃气轮机(12)的减速期间将入口放气热流提供至燃气轮机(12)。该指令还促使控制器(36)接收第一温度、燃气轮机(12)的转速、以及入口放气热流速。此外，该指令促使控制器(36)至少基于第一温度、转速、以及入口放气热流速来计算排气流速。而且，该指令促使控制器(36)控制发电系统以在足以在燃气轮机(12)的减退期间达到吹扫体积的燃气轮机(12)的正常操作速度的一部分下使燃料源与燃气轮机(12)隔离。
摘要（英）：

A system includes a controller of a power generation system including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to control the power generation system to provide inlet bleed heat flow to a gas turbine during deceleration of the gas turbine. The instructions also cause the controller to receive a first temperature, a rotational speed of the gas turbine, and an inlet bleed heat flow rate. Additionally, the instructions cause the controller to calculate an exhaust flow rate based on at least the first temperature, the rotational speed, and the inlet bleed heat flow rate. Further, the instructions cause the controller to control the power generation system to isolate a fuel source from the gas turbine at a portion of normal operating speed of the gas turbine sufficient to achieve a purging volume during coast down of the gas turbine.
