EV SYNCHRONOUS MOTOR-GENERATOR SET Mod. MGS-1/EV

Features

This control module contains all the supply and control devices for generator set mod. MGS-1/EV and enables students to learn and experiment with electric power production and the relevant protection systems, using real industrial components. The various installed electric devices, partially connected with each other and with safety terminals, are set at work with very simple and quick operations and they enable to create, modify and check the quality of the output power. All the protection and control devices of the electric machines used in the module are exactly the same as in industrial power plants. Hence, the sequence of management operations of this laboratory power station is exactly the same as necessary in industrial power plants. As this is a training and testing system, the starting operations of the generator set and the possible parallel with the mains are intentionally left to the operator, in order to let him understand the method. This generator set consists of a common base, that is a DC motor (which simulates a turbine or an endothermic engine) and a rotary-inductor synchronous generator connected with each other. The prime mover is provided with a tachometer to control and stabilize the speed of rotation.
Product Details

TECHNICAL CHARACTERISTICS:

The set consists of a base and of the electric rotary machines, it may be positioned an any working top or close to the control module. The base is made of chemically treated sheet steel, painted with many epoxy coats; the base is provided with rubber feet and it enables to couple the machines in a very quick way.

It is also provided with safety covers to be put over the couplings so that moving parts become inaccessible, and it includes an accessory to lock the shaft of the machine for tests with locked rotor (short circuit).

The electric rotary machines have structural shape B3 and a protection degree IP 22.

TRAINING PROGRAM:

Training refers to the study of machines for power generation and to control and regulation devices. The range of application of these devices is related to both big high-voltage power plants and small autonomous and/or low-voltage co-generation plants.

Main subjects dealt with:

  • Determination of resistance of the windings of a synchronous machine
  • Detection of mechanical losses, iron losses, copper losses, etc…
  • Determination of efficiency of a synchronous machine
  • No-load characteristic or magnetization characteristic of an alternator
  • Short circuit characteristic of an alternator
  • Determination of synchronous impedance
  • External characteristic of an alternator
  • Control characteristic for different power factors
  • V curves of a synchronous motor
  • Using a synchronous motor as compensator for power factor correction
