setting range of governor parameters

constant transformation coefficient bp=0~10%

transient slip coefficient bt=0~100%

buffering time constant Tb=0~20S

artificial failure zone IC =0~ 0.9hz

given frequency range fr=45~55Hz

1. measure the frequency of the unit and the power grid, and realize the frequency regulation of the unit when it is running without load or in isolation;

2. when no load is on, the unit frequency automatically tracks the power grid frequency, which is convenient for rapid automatic synchronization;

3. manually start and stop, increase and decrease load, and operate with load;

4. automatically start and stop the machine, and automatically adjust unit output according to permanent slip (bp) after grid connection;

5. switch automatically and manually unconditionally and without disturbance;

6. main parameters and operation status of speed regulators such as machine frequency, network frequency, guide blade opening, manual and automatic are displayed on the display screen;

7. able to set the operating parameters of the governor through the display screen;

8. when an electrical fault is detected, it can be automatically cut to manual and the load can be fixed in the state before the fault.

9. high reliability programmable controller (PLC), small size, strong anti-interference ability, and an average trouble-free time of more than 300,000 hours;

10. software frequency measurement can meet the requirements of timing and accuracy of frequency measurement;

11. PID intelligent control, with good stability and adjustment quality
