一.A Review of 30-600kw Electric Generator.
30-600Kw TFW series three-phase brushless synchronous generator is a self-designed and developed new model by introduction, digestion and absorption of advanced generator technology over the world.
The technical performance and installation dimension of TFW series generators accord with international standard IEC and national standard GB/T15548-95“General Technical Conditions for Reciprocating Internal Olefins Machine-Driven Three-Phase Brushless Synchronous Generator ”Products are of excellent performance, reliable quality, exquisite appearance and up to international standards.
二．30-600kw Generator Features
Excellent electrical properties
Steady-state voltage regulation rate ≤ ± 1.0%
Transient voltage regulation rate ≤ + 20% -15%
Voltage setting range ≥10% UN
Line voltage sinusoidal waveform distortion rate ≤5%
Three-phase asymmetric load voltage deviation rate ≤5%
Efficiency average reaches advanced international level
Excellent structure design
Integral salient pole rotor is covered directly with pole winding. Unique core ventilation design to ensure good heat dissipation effect and larger temperature margin of winding. Rotor is equipped with integral damping winding which will ensure steady parallel operation. Cylinder-shaped steel base features an exquisite appearance, small volume, light weight, and novel style. The AVR is of high accuracy and integral sealed. Overall structure has two kinds: single type (with excitation box) and small self-contained style (with control box). End cover also has two kinds: one kind is with flange spigot, another is casted together with connecting base so as to facilitate the installation of generator sets.
