CONTROL AND PROTECTION SYSTEMS


GENERAL

The gas turbine has a number of control and protection systems designed for the reliable and safe operation of the unit. This section presents the general operating characteristics of turbine control and protection. For settings and adjustments refer to the, Control Specifications Included in the manual. The Turbine Control Sequence Programme Diagrams, sent to the Installation, will provide additional Information.
Control of the turbine is done mainly by startup, speed, acceleration, synchronization, and temperature control. Figure CPFR-1 illustrates the three control modes, and the means of fuel control in relation to the fuel command signal. Sensors monitor the turbine speed, temperature, and compressor discharge pressure to determine the operating conditions of the unit. When it is necessary for the turbine control to alter the turbine operating conditions because of changes in load or ambient conditions, it is accomplished by modulating the flow of fuel to the turbine. For example, if the exhaust temperature starts to exceed its permitted value for a given operating control condition, the temperature circuit will cause a reduction in the fuel supplied to the turbine and thereby limit the exhaust temperature.

控制与保护系统一般燃气轮机有许多控制和保护系统，为机组的可靠和安全运行而设计的。本节介绍了水轮机的控制和保护的一般工作特性。对于设置和调整指的是，控制规范包括在手册中。的涡轮控制序列程序图，发送到安装，将提供额外的信息。汽轮机的控制主要是通过启动、速度、加速度、同步和温度控制来完成的。图cpfr-1说明了三种控制模式，并对燃料的燃料控制指令信号的方法。传感器监测涡轮转速、温度和压缩机的排气压力，以确定机组的运行状况。当有必要为涡轮机控制改变涡轮机的操作条件，因为在负载或环境条件的变化，它是通过调节燃料的涡轮机的流动。例如，如果排气温度开始超过其允许值对于一个给定的操作控制条件，温度电路将导致减少在提供给涡轮机的燃料，从而限制了排气温度。
