Problems solved by technology

[0002] Gas turbines are widely used in industrial enterprises, and their stand-alone power ranges from tens of watts to hundreds of kilowatts. The basic technical feature is the radial flow impeller machinery, which is a centripetal turbine and a centrifugal compressor. The impeller is back-to-back structure, and the regenerator is generally high-efficiency plate-fin type. Some units also use air bearings, which do not require a lubricating oil system. This structure is relatively simple, and the combustion controller is an important part of the gas turbine. The current combustion controller product variety Most of them use programmable logic controllers (PLC) for integrated control in control technology. The advantages are simple structure, easy operation, and are widely used. complex

Embodiment Construction

[0140] The detailed structure of the present invention is described in conjunction with accompanying drawing and embodiment.

[0141] The structure of the gas turbine control device is shown in Figure 1.

[0142] The system adopts TMS320F2407 series digital signal processor as the CPU chip. According to the communication function (CAN bus), the TMS320F2407A chip is selected and equipped with enough external storage space. The power consumption of the controller is reduced, and the instruction cycle is shortened to 25ns, thereby improving the real-time control capability of the controller. It has up to 32K words of FLASH program memory, up to 1.5K words of data / program RAM, and 544 words of dual-port RAM (DARAM) and single-port RAM (SARAM) of 2K words, the total space of expandable external memory is 192K: 64K word program memory space; 64K word data memory space; 64K word I / O addressing space. It has two modules EVA and EVB, a timer module (WDT), a 16-way 10-bit A / D converter...

Abstract

The invention relates to a micro fuel gas turbine technology, whose structure includes turbine burning controller and control method. The controller includes PUT, detecting unit, output unit, photo-electricity coupling unit, and driving unit. The control method is realized by computer program module that includes system initialization, self-testing, burner firing, power closed loop adjusting block, stop and turbine capability index real time monitoring module. It adopts neural network PID controller adjusting method. It improves control accuracy, decreases technology cost and increases the stability and safety of the system.
