General Description

The Hydroelectric Power Plants Application with Pelton Turbine, "AEL-HPPP", has been designed by EDIBON with a double purpose: inone hand it allows to study the mechanical characteristics of a Pelton turbine (designed by EDIBON) and, on the other hand, it allows tostudy the operation of real hydroelectric power plants.

This application consists of real mechanical and electrical elements (reduced scale) for testing in laboratories.

Study of mechanical characteristics of the turbine:

  • The "AEL-HPPP" Application consists of a water tank (water reservoir) from which the water is propelled via pipe through a highpower water pump (potential energy) up to an injector in which is installed a pressure sensor. Injector injects water into the Peltonturbine, which consists of 16 appreciable vanes from the transparent cover of the turbine. This application offers the advantage ofcontrolling the water pressure of the injector via pump speed control (flow/pressure variations). The pipe output of the water pumphas a flowmeter that allows measure the water flow injected into the turbine. On this way different pressures can be got to analyzeseveral operation regimes of the Pelton turbine, as well as power generation variations.
  • Thus, it is included a torque sensor, abraking system and a load cell to measure the turbine torque. This allows to obtain the characteristic curves of the turbine.

Study of hydroelectric power plants:

  • Because its versatility and flexibility, this application permits to study the operation of both large hydroelectric power plants, thatprovide energy into the grid (parallel operation mode), and mini hydroelectric centers that provide energy to an isolated grid (standaloneoperation mode).
  • A 1kW three-phase induction generator is coupled to the Pelton turbine shaft in order to synchronize the generator to the laboratorygrid (50 Hz or 60 Hz).
  • The "AEL-HPPP" has an automatic grid connection device with pre-insertion resistors, to avoid sudden torque changes in thegenerator and turbine at the time of synchronization.
  • A network analyzer is connected to the induction generator terminals to monitor the power generation parameters such as activepower, reactive power, apparent power, phase currents, frequency and power factor. In addition, this application has a capacitorbench that provides reactive energy to the generator when user works with the application as mini hydroelectric central (stand-alonemode), providing power to a local electric load (included).
