Description
The IS200EPSMG1ABB consists of several large components. This includes a transformer in a frame and a large inductor marker Bicron B9309 0912. There is another smaller inductor coil (L2.) On the circuit board there are 5 transistors with heat sinks. They are located directly behind the front panel. Four additional cooling elements are installed on the surface of the plate. IS200EPSMG1ABB uses high voltage and axial electrolytic capacitors. There is a single-disk capacitor in the upper right corner of the board. Other capacitors are also located on the board. The plate uses a metal film and a carbon composite resistor. Nine fuses are located on the circuit board surface. Most of these are located in the upper left quadrant, but fuse 7 is located on the right side of the board. The board also includes several integrated circuits, TP test points, and two backplane connectors.
Function description:
The main role of excitation system IS200EPSMG1ABB is to supply DC power to the excitation winding of synchronous generator. Its role in synchronous generator can be reflected in the following aspects:
1. Adjust excitation to maintain voltage stability.
2. The reactive power can be reasonably distributed among each unit.
3. The perfect excitation system and its automatic regulating device can improve the transmission power limit and expand the range of static operation.
4. In case of short circuit, forced excitation is beneficial to improve dynamic stability.
5. In the transient process, the behavior of the synchronous generator depends to a great extent on the performance of the excitation system.
