Abstract

The invention provides a miniature gas-turbine generator set control system. Through voltage transformation and filtering of a voltage transformation module and a filtration module, electricity is controlled to be supplied to a control system; command / switching signals are connected with the signal input end of a center control module through an optocoupler isolated-input module; temperature sensor signals are connected with the signal input end of the center control module through a signal adjusting module and an operational circuit module in sequence; rotate speed / frequency signals are connected with the signal input end of the center control module through a frequency measurement module; and the output end of the center control module controls the actions of a magnetic valve through a magnetic valve driving module. Due to the adoption of a fuzzy reasoning method, on-line automatic adjusting to generator set running PID parameters can be achieved, therefore, a fuzzy parameter automatic adjusting PID control algorithm used for starting control and power generation frequency control of a gas-turbine generator set is designed, therefore, the purpose of controlling to self adaption of different target generator sets can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gas turbine control, and in particular relates to a micro gas turbine generating set control system. Background technique [0002] The control system is an important part of the gas turbine generator set, which is mainly responsible for unit status monitoring, start-up control, power generation control, fault detection, shutdown control, etc. Therefore, the control system must not only have logic control, but also complex process control and various strict protection controls. [0003] Gas turbine startup control and power generation control are two important links in the operation of the unit, and the key point of the control of these two links is the control of the solenoid valve in the fuel system. [0004] In the traditional gas turbine control system, the conventional PID control method is usually used to control the fuel solenoid valve. That is to say, the engineers first set an initial PID contro...
