Hydroelectric Power Plants Application with Pelton Turbine (HPPP)
PL-581013
The Computer Controlled Hydroelectric Power Plant with Pelton Turbine, “HPPP,” by EDIBON provides a comprehensive platform for studying the mechanics and operation of hydroelectric plants that employ Pelton turbines, with particular emphasis on the turbine's specific mechanical characteristics.
Mechanical Design and Functionality: The “HPPP” unit is built with a robust aluminum and steel framework and houses a 1 kW Pelton turbine featuring dual servo-driven injectors. A simulated reservoir water tank and a pump capable of creating up to an 80-meter waterfall enable realistic hydraulic testing. The water is directed through 2-inch PVC piping from the pump to the injectors, controlled by two servomotors for precise injector adjustment, which can be managed either manually through the SCADA interface or automatically using an advanced controller. Embedded sensors track critical variables—flow rate, pressure, speed, and torque—allowing users to analyze aspects like turbine efficiency, torque fluctuations in response to injector settings, mechanical power output, water flow rates, and optimal performance conditions, along with the impact of injector asymmetry on efficiency.
Electrical Integration: For electrical performance, the unit is recommended for use with “N-REVT/1K” and “N-CAR19T/3C” resistive and capacitive loads, along with the HPPP Control and Regulation Unit “HPPP-CR.” This setup contains essential electrical components needed to regulate the Pelton turbine as a generator. Analog instruments like a voltmeter, wattmeter, and varimeter are included to measure electrical parameters, while an advanced controller automatically adjusts the injectors based on electrical output, incorporating safeguards against over-frequency, over-voltage, over-current, and reverse power. Additionally, a network analyzer allows real-time monitoring of parameters when the generator synchronizes with the main grid, with the capability to operate independently to supply power to specific loads.
EDIBON SCADA System Integration: The integrated SCADA system continuously logs both electrical and mechanical parameters, providing a detailed analysis platform for real-time graphical visualization of turbine operations. This system enables users to observe how pressure head impacts mechanical power, variations in efficiency based on injector adjustments, and the resulting effects on turbine torque, offering in-depth insights into the dynamics of hydroelectric energy systems.
