Abstract

A temperature collection device of micro-size gas turbine is prepared for connecting output ends of thirteen thermocouple temperature compensation circuits separately to input ends of thirteen thermocouple converters, connecting output ends of thirteen thermocouple converters to A / D port of digital signal processor and applying TM320LF2407A as said digital signal processor.

Description

Technical field [0001] The invention belongs to the technical field of gas turbines, and particularly relates to a temperature collection device of a micro gas turbine. Background technique [0002] Domestic research on micro-gas turbine power generation and control technology has just started, and is currently in the stage of introduction, absorption, research and development. Foreign countries have taken a step ahead in the research of micro-gas turbine generator sets and power conversion control systems, and have a more advanced and complete micro-gas turbine power supply system. Due to the needs of energy-saving work in our country, the large demand for industrial heat, the rapid increase of civil heating and domestic heat, and the development of small heat and electricity in rural areas, the micro-gas turbine power generation system has a very broad market application prospect. However, the current temperature collection of micro gas turbines for short gas turbines mostly ad...
