A method for upgrading a gas turbine control system

Abstract

The invention discloses an upgrading method of a gas turbine control system. The upgrading method comprises the steps that the integrated gas turbine control system is introduced, control software isunified and centralized in a controller, and one set of PLC control system is used for achieving all control functions; brand-new control logic is used for controlling a gas turbine; the complex gas turbine control system is divided into multiple independent modules, and mode control is achieved according to the work condition state stepping sequence; multiple kinds of control algorithms are introduced into the control logic to optimize the gas turbine control system; and multiple independent modular command algorithms cover all states of a turbine generator set, and control of each equipmentadjusting component is expressed through a module equation. The existing gas turbine control system is modified and upgraded, the modular stepping process control logic and the advanced control algorithms are adopted for achieving the processes of starting, running and fuel switching control of the gas turbine, and meanwhile precise control of the process of fuel switching control is guaranteed.

Description

technical field [0001] The invention relates to an upgrading method of a gas turbine control system. Background technique [0002] The gas turbine control system is the nervous system of the power station to ensure the safe and reliable operation of the unit. In addition to being equipped with advanced host equipment, the perfect regulation and control system can give full play to the greatest advantages of the gas turbine, and the gas turbine starts, runs, stops and protects The control has the characteristics of different and general variable working conditions, and is an important part of the gas turbine control system. Its characteristics are of great significance for improving the service life of the gas turbine; the overall requirements of the gas turbine control system: the gas turbine control system makes the gas turbine from stationary to cranking, Drive the turbine to the cleaning speed, which is about 20% of the rated speed, and then ignite. When the turbine speed...
