Automatic generation control and monitoring the mechanism of micro hydro power plant with impulse turbine and synchronous generator

This paper presents automatic generation control and monitoring operation of Micro Hydro power plant (MHPP), based on Impulse Turbine, synchronous motor with permanent magnet and a servo control spear valve. The key objective of this system is to show the benefits of automatic generation control and Human Machine Interface (HMI) for MHPP. Mainly, turbine governing system covers the automatic generation part. A deflector and a servo valve are used for turbine governing system and PID controller is used to adjust with the generator output. The PID controller is used for the deflector and servo valve. The PLC is used to control the whole mechanism and SCADA is combined with PLC for monitoring and supervising the system. The proposed scheme is verified with severe MATLAB simulation result and finally a small project confirmed the feasibility of this model. The output results of both simulation and real model proves that this model can work properly in real system.
