Problems solved by technology
[0004] As the gas turbine system becomes more and more complex, the traditional gas turbine control algorithm mostly uses fixed PID parameters to control the entire working process of the gas turbine, which may easily lead to poor adjustment accuracy of the gas turbine control system and overshoot phenomena; in addition, the traditional gas turbine control algorithm uses PID parameter setting mostly adopts engineering test, and it needs repeated iterations in the engineering test to obtain the final parameters, which increases the design cycle of the gas turbine control system and easily causes equipment damage during the test run

The invention discloses a method for adjusting PID parameters, a main controller and a storage medium, which are used to solve the technical problem that the PID parameter adjustment period of the gas turbine control system is long in the prior art. The method includes: obtaining the current rotational speed of the gas turbine; when the first difference between the current rotational speed and the target rotational speed of the gas turbine is greater than a set threshold, obtaining the current rotational speed from a preset scheduling table based on the current rotational speed. PID parameter value; wherein, the set threshold is used to make the current speed follow the target speed, and the preset schedule is the corresponding relationship between each speed of the gas turbine and the PID parameter value used; using the The current rotational speed corresponds to the PID parameter value to adjust the first difference, so that the first difference is smaller than the set threshold.
Description
technical field [0001] The invention relates to the field of gas turbine control, in particular to a method for adjusting PID parameters, a main controller and a storage medium. Background technique [0002] With the widespread use of power plants with gas turbine technology as the core, gas turbine control systems that ensure the safe and reliable operation of gas turbines are becoming more and more important. [0003] In the gas turbine control system, the main controller is responsible for starting, controlling and monitoring the gas turbine, so as to give full play to the maximum advantages of the gas turbine. [0004] As the gas turbine system becomes more and more complex, the traditional gas turbine control algorithms mostly use fixed PID parameters to control the entire working process of the gas turbine, which may easily lead to poor adjustment accuracy of the gas turbine control system and overshoot. PID parameter tuning mostly adopts engineering test, which requi...
