MGS Series

RELIABILITY AND QUALITY IN POWER GENERATION

The growing strength of the Mitsubishi Brand name: MITSUBISHI MGS series DIESEL GENERATOR SET
The core of the MGS Gen Set is now -S typed diesel engines for MGS Power Rating

MITSUBISHI DIESEL ENGINES

Ranging in capacity from 0.5 to 56,400 horsepower, Mitsubishi brand diesel engines offer a series of versatile power generating systems. Mitsubishi Heavy Industries, Ltd. has continually introduced upgraded its engine products since the inception of business in 1917, and now the MITSUBISHI MGS series DIESEL GENERATOR SET provides a higher generating power rating and more advanced control systems than ever before, with proven reliability based on the continued research and development.

The best performance-matched engine system configured with Mitsubishi diesel engines and Mitsubishi turbochargers, which are engineered and manufactured in the same facility, is certain to result in the high productivity and improved fuel economy in the MGS Power Generation. Every unit is inspected and tested before leaving the factory and the test report is sent with the Gen Set. MITSUBISHI MGS - All Mitsubishi assembled, tested and supported.

DEPENDABILITY & DURABILITY IN POWER GENERATION

The best performance-matched engine and generator systems give world-class performance
Response and stability designed to exceed user expectations in a variety of applications

AC GENERATOR

4 pole, screen protected, drip-proof IP23, self-exciting, self-regulating and brushless with fully connected damper windings, salient pole rotors, A.C. exciter and rotating rectifier unit. The insulation system is Class 'H'. All windings are impregnated in either a triple dip thermo-setting moisture, oil and acid resisting polyester varnish or vacuum pressure impregnated with a special polyester resin. Electrical design in accordance with BS5000 Part 3, VDE0530, UTE51100, NEMA MG1-32, CEMA, IEC34-1, CSA22.2 and AS1359.
6 and 12 wire*1 reconnectable windings provide a wide range of 3 phase voltage. The exciter field system remains at full strength, sustaining a high level of short circuit current at the ac generator output terminals by means of the excitation voltage via AVR powered by the independent winding, Permanent Magnet Generator (PMG) as a standard feature in the MGS Gen Set, which is electrically isolated from the main alternator stator windings.
The fully sealed, three phase*2 RMS voltage sensing AVR maintains the voltage within the limits of +/-0.5%*3 from no load to full load including cold to hot variations at any power factor between 0.8 lagging and unity allowing for a 4% engine speed variation, suitable for applications with greatly unbalanced or high non-linear loads associated with UPS systems. The AVR has built-in protection against sustained over-excitation, caused by internal or external faults. This de-excites the generator after a minimum of five seconds. THF (as defined by BS4999 Part 40) is better than 2 % and a TIF (as defined by ASA C50.12) is better than 50. Radio interface: Suppression is in line with the provision of BS800 and VDE Class G and N.
Note: *1 12 wire reconnectable windings are the features up to Code H6 models.
  *2, 3 Up to Code K5 models have single phase voltage sensingand the voltage regulation within +/-1.0%, for 4% engine speed variation.
Turbo-filter is standard and paper element dry type air-cleaner is available as an option.

ADVANCED SOLUTION IN POWER GENERATION
