Technical Requirements:
Software design of microcomputer excitation regulator
PIC microcomputer excitation regulator software using PIC16F877 assembly language and C language mixed programming, human-machine interface friendly, simple operation. In addition, using the modular design idea, with the main program as the core, the design of each function module subroutine, so that a large number of functions in the subroutine to realize, simplify the software design structure. Subroutine module mainly includes system initialization and power-on self-test module, PID adjustment module, running mode tracking module, overexcited and underexcited control module, start and stop module, communication module and so on.
The system provides three different operating modes, namely constant voltage regulation, constant excitation current regulation and constant reactive power regulation. Different running modes can be switched by keyboard and set a given value. In addition, the system also sets a running mode tracking module, that is, the standby running mode outputs the tracking of the current running mode output, in order to achieve no disturbance when switching running modes.
Because the excitation system has inertial and hysteretic control objects, and requires higher control accuracy and faster response speed, the improved PID adjustment mode is adopted in this design, that is, the integral separation algorithm is used to eliminate the integral saturation benefit and reduce the overshoot. Meanwhile, the gain variable method is used to increase the proportional effect in the dynamic response and reduce the proportional effect in the steady-state process. To eliminate the large deviation and speed up the transition process, the excitation regulator has better regulation characteristics.
In order to improve the reliability of the entire system, in addition to the self-check during power-on, fault detection, fault tolerance processing and software watchdog are carried out during each calculation cycle.
