control system, the generator excitation control system, and the generator protection system were all replaced by the HIACS-MULTI 700 system. This retrofit project was very successful, and the HIACS-MULTI system is now operating smoothly at the PUSRI site. TABLE 1. Overview of the HIACS-MULTI SeriesGenerator Inspections, Failures Get a grip on stator-core, rotating-field damage mechanisms Generator stator cores are deceptively simple devices. But there's a lot that can go wrong with the 10 acres of insulated surface in a typical 200-MW unit. Rotating fields present their set of problems, some of which have led to catastrophic failures.

AC excitation systems utilize AC machines for generator excitation. Exciter is typically placed on the same shaft with the turbine. AC is rectified by controlled or non-controlled rectifiers, to provide DC to the generator field winding. Also AC excitation systems may differ by output control method and source of excitation for the exciter ...The magnetic field of the exciting generator 10 is created by permanent magnets 11 and 12. The exciting generator 10 includes a three-phase Y-connected armature 9 which provides the field excitation for a power generator 20, as will be further described. A tubularly shaped rotor 13 is common to the two generators.

Control Cubicle. The generator set control cubicle is located at the rear top of the generator set and contains controls and instruments for operating the engine and the generator. The control panel is grounded to protect the operator from electrical shock in the event of a short in the equipment. The generator section ofThe unit has a full wave rectifier. The input of this bridge rectifier is given from the output of the generator through the adjustable field rheostat housed in the termination box to provide the excitation current to the field coil for sufficient field strength. THE STATOR It consists of an outer frame, the field pole, and field coil, which ...

Other arrangements for field excitation are also used, one being a separate alternator mounted on the rotor shaft with direct rectification of the ac voltage. This eliminates the need for slip rings. Even though large generators have efficiencies well in excess of 90%, the energy dissipated (as heat) per second may amount to several megawatts.US9597567B1 US15/144,794 US201615144794A US9597567B1 US 9597567 B1 US9597567 B1 US 9597567B1 US 201615144794 A US201615144794 A US 201615144794A US 9597567 B1 US9597567 B1 US 9597567B1 Authority US United States Prior art keywords container handle membrane liquid shape Prior art date Legal status (The legal status is an assumption and is not a legal …
