Embodiment Construction

[0238]Below in conjunction with accompanying drawing, the present invention will be further described;

[0239] When the gas turbine (referred to as the gas turbine) is running, the combustion control device conducts online identification of the parameters of the gas turbine and controls it in real time, requiring concise software codes and high execution efficiency. In order to meet this requirement, we use assembly language to program the combustion control device. The control method of the combustion control device is divided into five modules: initialization and self-inspection of the control device, ignition of the gas turbine, closed-loop power adjustment, shutdown control, and real-time monitoring of gas turbine performance indicators.

[0240] 1. Control device initialization and self-test module

[0241] This part of the program should be prepared for the normal operation of the gas turbine, as shown in Figure (5), it is executed according to the following steps:

Abstract

The invention relates to a combusting control device of micro gas turbine and the control method. The combusting control device identifies parameters of gas turbine on line and control them in time. The control method makes use of the combination of conventional PID control and intelligent fuzzy control theory so that the control device has on-line parameter self-tuning function, which comprises initialization and self-check for control device, combustor ignition, power closed-loop adjustment, shut-down control and on-line monitoring index of gas turbine function. The invention is provided with high control accuracy, safety, stability and low development cost.

Description

technical field [0001] The invention belongs to the technical field of micro gas turbines, and in particular relates to a combustion control device and a control method of a micro gas turbine. Background technique [0002] Micro gas turbines will play an important role and strategic significance in my country's electric power, power and other national economic fields and national security in the future. Advanced gas turbine technology is the core key technology in the energy power system in the 21st century. The development of high and new technologies in the national economy and national defense construction such as aerospace, ships, vehicles, and military affairs is of great significance. The micro gas turbine is composed of a high-speed rotating impeller, and the energy generated by the combustion of fuel is used to do work through the turbine to generate electrical energy to supply power to the load. It is mainly composed of compressors, combustion chambers, turbines, so...
