MGS-1 Synchronous M-G Set Didactic Equipment Electrical Lab Equipment
This control module contains all the supply and control devices for generator set mod. MGS-1 and enables students to learn and experiment with electric power production and the relevant protection systems, using real industrial components. TRAINING PROGRAM: Training refers to the study of machines for power generationand to control and regulation devices. The range of applicationof these devices is related to both big high-voltage powerplants and small autonomous and/or low-voltage co-generationplants. Main subjects dealt with: • Determination of resistance of the windings of a synchronousmachine • Detection of mechanical losses, iron losses, copper losses,etc… • Determination of effi ciency of a synchronous machine • No-load characteristic or magnetization characteristic of analternator • 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 factorcorrection TECHNICAL CHARACTERISTICS: SYNCHRONOUS MOTOR-GENERATORSET - Mod. MGS-1 The set consists of a base and of the electric rotary machines,it may be positioned an any working top or close to the controlmodule. The base is made of chemically treated sheet steel,painted with many epoxy coats; the base is provided withrubber feet and it enables to couple the machines in a veryquick way. It is also provided with safety covers to be put over thecouplings so that moving parts become inaccessible, and itincludes an accessory to lock the shaft of the machine for testswith locked rotor (short circuit). The electric rotary machines have structural shape B3 and aprotection degree IP 22. Direct current motor: Rated power = 1100 W Armature voltage = 160 Vdc Speed of rotation = 3000 rpm Separate excitation Tachogenerator of 0.06 Vdc/rev, coupled to the motor Thermal protector integrated in the windings Three-phase synchronous salient pole alternator: Rated power = 1000 VA Armature voltage = 3 x 230/400 Vac Star delta connection Speed of rotation = 3000 rpm Separate excitation = 220 Vdc Thermal protector integrated in the windings Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
