Abstract

The invention discloses a method for stabilizing output power of a vaneless turbine. An ultrasonic generation module is arranged on the inner side of a shell, ultrasonic waves emitted by the ultrasonic generation module are perpendicular to the flowing direction of a medium, the ultrasonic generation module corresponds to the radius length of a disc and generates ultrasonic waves on the rotating disk in response to a received control signal; based on obtained medium parameters of the vaneless turbine and the geometric structure and size of the vaneless turbine, characteristic data of output power are calculated, a characteristic function of an acting medium is fitted, and when it is detected that the output power of the vaneless turbine is smaller than a preset value, the control signal is sent to start the ultrasonic generation module; when it is detected that the output power of the vaneless turbine is larger than the preset value, the control signal is sent to start the ultrasonic generation module; and when it is detected that the output power of the vaneless turbine is equal to the preset value, the output power of the vaneless turbine is stabilized.

Description

technical field [0001] The invention relates to the technical field of turbine control, in particular to a method and system for stabilizing the output power of a bladeless turbine. Background technique [0002] A gas turbine is a rotary power machine that uses continuously flowing gas as a working medium to convert heat energy into mechanical work. As an advanced thermal power device, gas turbines have been widely used in various industrial fields such as aviation, ships, locomotives, electric power, and petroleum. Traditional heavy-duty, high-power gas turbines are mainly used as aviation power plants and generator sets. With the development of distributed power supply systems and the demand for new types of power with high power density and low fuel consumption, micro and ultra micro gas turbines have received great attention from all over the world. [0003] The simple circulation system of a gas turbine is mainly composed of three major components, such as a compresso...
