CONFIGURATION AND SCOPE OF SUPPLY

GENERAL

The generator is designed to operate together with a diesel or a gas engine. CONSTRUCTION

The stator frame is a rigid welded steel structure construction. The stator core is built of thin electric sheet steel laminations which are insulated on both sides with heat-resistant inorganic resin. The radial cooling ducts in the stator core ensure uniform and effective cooling of the stator. The rotor consists of a shaft, a hub and poles fixed on the hub. The shaft is machined of steel forging. The poles are manufactured of 2 mm sheet steel and bolted to the hub. The pole laminations are pressed together with steel bars which are welded to the end plates. All windings are completely vacuum pressure impregnated with high quality epoxy resin. The windings are provided with very strong bracing which withstands all expected mechanical and electrical shocks and vibrations as well as chemicals. For more information ask for brochure "MICADUR-Compact Industry Insulation System". The stator frame and pedestals are made of fabricated steel. The stator frame is closed with steel panels that guide the ventilation air and provide the degree of protection required. The pedestals are integrated to stator frame. According to IM7303 the machine has two pedestal bearings. The feet are raised. Conical shaft end. FOUNDATION

The machine can be mounted using shimming, machined blocks, chock fast or on grouted sole plates or bed plate. Before using other mountings, contact us. COOLING

The machine has two shaft mounted fans inside. The surrounding air is used for cooling. The cooling air is drawn in through air filters (self charging electrostatic panels) and blown out to the surrounding environment. CONTROL SYSTEMS

A three phase transformer supplies the excitation power to the field winding of the shaft driven three phase exciter under the control of the digital automatic voltage regulator (AVR) type ABB UNITROL 1000. A three phase voltage feedback is supplied by the voltage transformer. A current feedback is provided by the current transformer. The transformers are installed in the generator. Thanks to a permanent magnet pole in the exciter no external power source is required for initial excitation at start-up. The permanent magnet pole is already magnetized by the generator manufacturer. Should the re-magnetization of the permanent magnet be necessary, rated values for re-magnetization given on the main connection diagram of the generator are used. Thanks to Soft Start function it is possible to avoid over shooting at start-up.

Excitation power at short circuit is supplied by the CTs through rectifier. At normal voltage the contactor is shorting the output of CTs (and preventing over excitation from these CTs). At a line short circuit AVR will notice the voltage drop and connect CTs to give full short circuit excitation. ECL-10 current limiter limits sustained short circuit current approx. 250 - 300 % of rated current. The circuit breaker protects the field circuit and the AVR against thermal overload and short circuit. The over voltage relay will trip the circuit breaker in excess of pre-set limit of over voltage and thus interrupt the supply of the excitation power to the AVR. Auxiliary supply can be 9 to 250 Vac (3-phase), 50 to 250 Vac (1-phase) or 18 to 300 Vdc. UNITROL 1000 AVR can be operated using digital and analogue I/O signals, from local panel or with CMT1000 PC software. CMT1000 is a commissioning and maintenance tool running under Microsoft Windows. With CMT1000 the tuning of the AVR can be done easily, also by using preset parameter files. The operation of a synchronous machine can be monitored and controlled by an on-line power chart, four channel oscilloscope and by several measurements and status indications with trending and memory functions. Measured data and parameters can be saved to a file for future use and analysis.
