Abstract

The invention provides a control device a control method for the stable running of a gas turbine, belonging to the technical field of the control of the gas turbine. The device comprises a start control module, a revolving speed control module, a revolving speed load control module, an acceleration control module, a temperature control module, a load shedding control module, a maximum value control module, a minimum value control module, a minimum value selector and a maximum value selector. According to the invention, the safety and the stability of the running process of the gas turbine can be guaranteed, the joint debug time of the gas turbine can be shortened, and the gas turbine debugging cost for the debug control system can be reduced; and a master control system is designed by the method adopting the minimum value selector, and the control system is debugged in cooperation with a simulated mathematical model, so that the rationality and the safety of the control system can be guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of gas turbine control, and in particular relates to a stable operation control device and control method of a gas turbine. Background technique [0002] The gas turbine control system is generally divided into a sequence control system, a protection system and a main control system. The main control system is the core of the control of the gas turbine. The gas turbine controls the start of the gas turbine by adjusting the amount of fuel by the main control system. Control of the entire process of stopping and running. Therefore, the algorithm of the main control system plays a decisive role in controlling the safe and stable operation of the gas turbine, and the reasonableness and stability of the algorithm can only be verified when the control system and the gas turbine are operating in conjunction, which greatly extends the fuel consumption. Commissioning time and commissioning costs incurred. Summary of the...
