Abstract

The invention relates to a method for controlling automatic start of a combustion turbine. The method comprises that: rotating speed of the combustion turbine is measured through a rotating speed measurement device of the combustion turbine; an inlet temperature of the combustion turbine is measured by an environmental temperature measurement device; a rotating speed signal and a temperature signal are both transmitted to a programmable controller; the programmable controller calculates corrected speed through the rotating speed signal and the temperature signal, and adjusts the opening capacity of an oil supply valve through a fuel controlling device according to oil delivery of the corrected speed at 15 DEG C; and after the combustion turbine is fed with fuel to achieve balanced rotating speed, the combustion turbine drives a load to work. The method can realize that automatic start of the combustion turbine can be controlled at different environmental temperatures, and can lead the combustion turbine to automatically start to the balanced rotating speed.

Description

[0001] Field [0002] The invention relates to a control method for automatic starting of a gas turbine. Background technique [0003] The start-up process of existing gas turbine generator sets mostly adopts open-loop control, that is, the oil supply volume of the gas turbine is adjusted according to the rising speed value, and the fuel supply volume gradually increases with the increase of the speed, and finally reaches the equilibrium speed of the gas turbine Effect. However, during the start-up process of the gas turbine, the characteristic curves of the rotational speed and the fuel supply amount will have certain differences depending on the ambient temperature. The low-temperature characteristic curve will easily cause the exhaust gas temperature of the gas turbine to be too high when the ambient temperature is high, while the characteristic curve suitable for higher temperature often has insufficient oil supply under low temperature conditions, resulting in the gas tu...
