Problems solved by technology

Mechanical fuel regulators have high requirements on shape and position tolerances and material properties, and the structure is complex
Analog circuit controller has large temperature drift and poor environmental adaptability
At the same time, the two are generally only suitable for micro gas turbines with specific performance. After the control law changes, it is difficult to adjust: the mechanical fuel regulator often needs to redesign the structural size of the internal components, and the processing cycle is long and the cost is high.

Embodiment Construction

[0029] As shown in the figure, the control method of the micro gas turbine includes the following steps:

[0030] 1) The main program starts;

[0031] 2) Turn off the total interrupt;

[0032] 3) DSP processor initialization:

[0033] 4) Whether the micro gas turbine status self-inspection is successful, if successful, go to the next step, otherwise continue the micro gas turbine status self-inspection until it succeeds;

[0034] 5) Light up the indicator light of "Enable start";

[0035] 6) Open interrupt;

[0036] 7) Do you need to modify the control parameters? If so, modify the control parameters and execute the next step; otherwise, directly execute the next step;

[0037] 8) Whether it is necessary to calibrate the analog quantity, if it needs to be calibrated, perform the next step after the analog quantity is calibrated, otherwise directly perform the next step;

[0038] 9) Whether it is necessary to read the historical data of the micro gas turbine to the host co...

Abstract

The invention relates to a control method of a micro gas turbine. A digital signal processor DSP is adopted as a central processing unit CPU in a digital control device of the micro gas turbine, and the software of the micro gas turbine is divided into a drive layer, an intermediate layer and an application layer according to the modular design idea. The drive layer is the bottommost layer of the control software, a drive layer program is called by an intermediate layer program to finish the program design of a specific function module, and the control function is performed by an application layer program according to the control requirement of the micro gas turbine. According to the control method, the working conditions such as starting, stopping, cold running, load running and the like of the micro gas turbine can be automatically adjusted, so that the requirements of the micro gas turbine in the aspects of economy and service life are met; and meanwhile, when the control law of the micro gas turbine is changed, the control parameters can be changed by the software, so that the control method can be widely applied to gas turbines with different control law requirements.

Description

technical field [0001] The invention relates to a control method, in particular to a control method of a micro gas turbine. Background technique [0002] Most of the existing micro gas turbine controllers use mechanical fuel regulators or analog circuit controllers to adjust the fuel and then control parameters such as the speed of the micro gas turbine and the exhaust temperature after the turbine. Mechanical fuel regulators have high requirements on shape and position tolerances and material properties, and their structures are complex. The analog circuit controller has large temperature drift and poor environmental adaptability. At the same time, the two are generally only suitable for micro gas turbines with specific performance. After the control law changes, it is difficult to adjust: the mechanical fuel regulator often needs to redesign the structural size of the internal components, and the processing cycle is long and the cost is high. The analog circuit controlle...
