| Abstract: | A Programmable Computer Controller based stepping motor driven governor for Kaplan turbines is proposed. The governor generates directly pulses to control the rotation of the stepping motors, measures frequencies of the unit and network with its internal high speed counting pulses. The performance testing function is integrated into a PLC based governor at the first time. Its software is developed by a high level language, instead of Ladder Diagram. It features high reliability of a PLC, programming flexibility of C language, and short real time of IPC. |
