The invention belongs to a method for controlling parallel operation of two combustion turbines. By the method, automatic adjustment of fuel delivery of the combustion turbines can be realized through calculating a rotating speed signal sent by a rotating speed measuring device of the combustion turbines and a torque signal sent by a torque measuring device of a parallel mechanism and outputting calculated signals to a fuel adjusting device, wherein the signals are acquired by two programmable controllers; and automatic adjustment of fuel delivery of the combustion turbines can adjust the rotating speed of the two combustion turbines, so that automatic control of output shaft torque of the combustion turbines on the parallel mechanism can be realized. The method has the advantages of automatic adjustment of the combustion turbines, quick response speed of the signals, power optimized distribution of combustion engine load and the like, and can be widely applied to a parallel operation system ...

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 thecombustion ...
