Real-time control device and method for angles of inlet guide vanes of gas compressor

Abstract

The invention provides a real-time control device and method for the angles of inlet guide vanes of a gas compressor. The real-time control device and method aim to solve the existing problems that the angle control precision of the inlet guide vanes of the gas compressor of an gas turbine or an aero-engine is not high, and the real-time performance is poor. According to the real-time control device, an angular displacement sensor and a guide vane adjusting mechanism are additionally arranged in a gas turbine or aero-engine control system, in the working process of an inlet guide vane device of the gas compressor, the angle values of the guide vanes are measured in real time through the angular displacement sensor, the angles of the guide vanes are fed back to a gas turbine controller in real time, the gas turbine controller adjusts the angles of the inlet guide vanes of the gas compressor in real time through a control program, and therefore the inlet air flow can be changed, the working margin of the gas compressor can be guaranteed, and surge can be prevented from occurring. The device and the method have a wide application value.
