INTRODUCTION 1. 概述 The SPEEDTRONICTM Mark VI Gas Turbine Control System is the latest derivative in the highly successful SPEEDTRONICTM series. Preceding systems were based on automated turbine control, protection and sequencing techniques dating back to the late 1940s. The main functions of the MARK VI turbine control system are as follows: SPEEDTRONICTM Mark VI燃机控制系统是必威体育精装版推出的、最成功的SPEEDTRONICTM 系列的过程控制系统。该系统继承了GE公司自20世纪四十年代以来的燃机自动控制、保护和顺序控制技术。MARK VI燃机控制系统的主要功能如下： Speed control during gas turbine startup 燃机启动期间的转速控制 Automatic generator synchronization 发电机自动同期控制 Gas turbine load control during normal operation on the grid 发电机正常并网运行中的燃机负荷控制 Protection against turbine overspeed on loss of load 在甩负荷时燃机的超速保护 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 sensors 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 servo 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
