GB/T 14411-2008Control and protective system for aero-derivative gas turbine (English PDF)

3.1 Basic requirements

3.1.1 gas turbine control system should be able to meet the need for control, regulation, monitoring and protection functions, as well as a high degree of reliability, safety And availability, should be consistent with GB/T 10489 requirements.

3.1.2 digital electronic control system should be redundant, fault-tolerant and self-diagnostic function. System hardware should be modular, universal, and easy maintenance. Control software should have excellent real-time, fault tolerance and security, programming convenience, easy to use.

3.1.3 digital electronic control system should provide a good man-machine interface, convenient connection with other control devices, is scalable and open Caving.

3.1.4 digital electronic control system should have the standard communication interface. The system can exchange data through the use of open communication interface with the outside world, Standard communication protocols, should be able to easily integrate into the upper system.

3.2 Control Function

3.2.1 Start

3.2.1.1 Overview

Starting from the beginning until the gas turbine auxiliary equipment to reach the empty load speed (slow speed) the whole process of starting the process. Starting manual Start, start semi-automatic, automatic starting, etc., may have to start a program, starting times and special start functions.

3.2.1.2 Starting method

3.2.1.2.1 Manually starting device according to supply and demand sides agreed programs. Manual start requires the operator to manually start auxiliary device Equipment, and gradually complete the start-up procedure until you reach the empty gas turbine load speed (slow speed).

3.2.1.2.2 semi-automatic starting aids manually start, but by the time the operator should operate the gas turbine automatically subsequent full Unit start-up process.

3.2.1.2.3 automatic start start command is issued by the operator, automatically complete all of the gas turbine start-up process.

3.2.1.3 Starting Process

To start the process of a complete set of start-up procedure to ensure reliable ignition and fuel supply as required, so that the gas turbine rapid, stable, Reliably reach the empty load speed (slow speed). Typically, with the turbine speed or by varying the starting time of the fuel supplied to the curve. Such as Necessary, should be able to fix this by starting curve ambient atmospheric pressure and temperature. Other parameters may also change or correction curve control start burning Quantity.
