1. 概述
The SPEEDTRONICTM Mark VI Gas Turbine Control System is the latest derivative in the highly successful SPEEDTRONICTM ries. Preceding systems were bad on automated turbine control, protection and quencing techniques dating back to the late 1940s. The main functions of the MARK VI turbine control system are as follows:

The SPEEDTRONIC™ Mark VI Gas Turbine Control System employs current state-of-the-art technology, including triple-redundant 32-bit microprocessor controllers, two-out-of-three voting redundancy on critical control and protection parameters and Software-Implemented Fault Tolerance (SIFT). Critical control and protection nsors are triple redundant and voted by all three control processors. System output signals are voted at the contact level for critical solenoids, at the logic level for the remaining contact outputs and at three coil rvo valves for analog control signals, thus maximizing both protective and running reliability. An independent protective module <p> provides triple redundant hardwired detection and shutdown on overspeed along with detecting flame. This module also synchronizes the turbine generator to the power system.
MARK VI燃机控制系统采用当今最先进的技术,包括采用三冗余32位微处理器控制器,对重要的控制和保护参数采取三选二的表决方式和软件容错技术(SIFT)。用于重要的控制和保护的传感器也采用三重冗余,并由三个控制器处理器进行表决。对于像电磁阀这种开关量元件的控制,系统的输出信号是经表决的开关量信号、三个线圈的伺服阀,则需要经表决的模拟量信号,从而使得保护和运行最为可靠。系统中采用了一块独立的保护模块,
其采用硬接线方式,对超速和火焰检测信号进行停机保护。该保护模块也用作发电机并网时的自动同期控制。
The Mark VI Control System is designed to fulfill all gas turbine control requirements. The include control of liquid, gas or both fuels in accordance with the requirements of the speed, load control under part-load conditions, temperature control under maximum capability conditions or during startup conditions. In addition, inlet guide vanes and water injection are controlled to meet emissions and operating requirements. Sequencing of the auxiliaries to allow fully automated startup, shutdown and cooldown are also handled by the Mark VI Control System. Turbine protection against adver operating situations and annunciation of abnormal conditions are incorporated into the basic system.

The operator interface consists of a color graphic monitor and keyboard to provide feedback regarding current operating conditions. Input commands from the operator are entered using a cursor positioning device. Communication between the operator interface and the turbine control is through the three control processors called <R>, <S> and <T>. The operator interface also handles communication functions with remote and external devices. SIFT technology protects against module failure and propagation of data errors. A panel mounted back-up operator display directly connected to the control processors, allows continued gas turbine operation in failure of the primary operator interface.
操作员接口由一台彩色图形监视器和键盘组成,用来提供当前运行的数据信息。操作员的输入命令用鼠标完成。在操作员接口和燃机控制器之间的通讯是通过饲育x彼女<R>、<S>、<T>三个控制处理器完成,操作员接口也有和远程装置、外部装置进行通讯的功能。采用容错技术可以防止模块故障和错误数据的扩散。安装一个备用操作员显示器,而这个显示器直接连接到控制器处理器,这样,在主操作员接口组件故障时,燃机仍可连续运行。
Built-in diagnostics for troubleshooting purpos are extensive and include “power-up” an
d manually initiated diagnostic routines capable of identifying both control panel and nsor faults. The ability for on-line replacement of boards is built into the panel design and is available for tho turbine nsors where physical access and system isolation are feasible. Set points, tuning parameters and control constants are adjustable during operation using a curity password system to prevent unauthorized access. Minor modifications to quencing and the addition of relatively simple algorithms can be accomplished when the turbine is not operating. They are also protected by a curity password.
