With industrial control level microcontroller 80 C552 as the core, the company has developed a dual microcomputer type electric regulator integrating frequency measurement, speed regulation, power adjustment, on and off operation, fault diagnosis and communication with host computer, Strong ability, high positioning accuracy, small amount of oil leakage stepper motor pilot valve and mechanical hydraulic follow-up device with the match, constitute a new type of governor: stepper turbine governor. The test results show that the governor has a good static and dynamic performance and high reliability, the performance indicators have reached the national standard GB / T9652 .1-1997 requirements.
