Description
Generators for diesel engines are synchronous machines for diesel generator sets that cover peak loads and provide emergency and standby power for critical facilities: hospitals, airports, satellite centres, data centres and plants with continuous processes. The main engineering challenge is that the piston engine transmits significant cyclic loads to the generator and causes strong vibration. The manufacturer designs rotors and stators with allowance for these loads; rotor dynamics and stator strength are calculated by the finite element method. Catalogue parameters: rating 1–32 MVA, voltage up to 15 kV, frequency 50/60 Hz, speed 187–1800 rpm, class F insulation with temperature rise to class F or B, design ambient temperature 40 °C (can be changed for the site). Rolling or sleeve bearings, protection degree IP23–IP54, terminal box at the side, top or bottom. The shaft end is cylindrical, flanged or with an SAE flange. The rotor is salient-pole or non-salient-pole; excitation is brushless or static; PMG, slip rings and an automatic voltage regulator mounted on the machine are available. Marine generators certified by Lloyd's Register and the Indian Register of Shipping (IRS) are produced separately; the website mentions marine diesel generators up to 200 MW. For marine environments, corrosion-resistant materials and coatings, protection IP55 and IP65, auxiliary terminal boxes and stainless steel cable glands are used. A hydraulic rotor lifting device for slow turning, a rotor earth-fault monitoring system (GDS) and online partial discharge monitoring are provided. Explosion-proof versions for Zone 2 / Division 2 (Ex e, Ex p) are possible. An example delivery: six 2.5 MVA generators and four 3.75 MVA generators at 1000 rpm for a diving support vessel of the Indian Navy built by Hindustan Shipyard. Manufacturing takes place at the plants in Bangalore and Turkey; the manufacturer is certified to ISO 9001, ISO 14001 and ISO 45001; deliveries to Europe are marked CE/UKCA, and GOST R and TR CU certificates are also available.
